2 SAFETY INSTRUCTIONS SM3300 Interfaces
1 Caution
The following safety precautions must be observed during all phases of operation, service and repair of this equipment.
Failure to comply with the safety precautions or warnings in this document violates safety standards of design, manufacture
and intended use of this equipment and may impair the built-in protections within. Delta Elektronika shall not be liable for
user’s failure to comply with these requirements.
2 Installation Category
The Delta Elektronika power supplies have been evaluated to installation category II (Over voltage category II).
3 Grounding of Mains Input
This product is a safety Class 1 instrument. To minimize shock hazard, the instrument chassis must be connected to the AC
Power Supply mains through a three or four conductor power cable for resp. a single or three phase unit, with the ground
wire firmly connected to an electrical ground (safety ground) at the power outlet.
For instruments designed to be hard-wired to supply mains, the protective earth terminal must be connected to the safety
electrical ground before another connection is made. Any interruption of the protective ground conductor, or disconnection of
the protective earth terminal will cause a potential shock hazard that might cause personal injury.
4 Grounding of Power Output
If the output of a unit is specified to deliver maximum 60VDC, and either the negative or positive power output is grounded,
the voltage on the power outputs and sense connections can be considered safe.
Caution 1: If a low voltage unit has both power outputs floating, or if the output is in series with an external high AC or DC
voltage, the negative power output can exceed the safe value in respect to ground as specified in the above warning!
Caution 2: Although a high voltage unit is set to a safe voltage below 60VDC, for safety it must always be considered as high
voltage unit! Wrong operation, a programming error or an external defect can result in an unsafe high output voltage.
For more information and schematics regards Grounding and Safety, see the special application note
"Safe operation of a
power supply"
on the Delta Elektronika website.
5 Fuses
Fuses must be changed by authorized Delta Elektronika service personnel only, for continued protection against risk of fire.
6 Input Ratings

8 Parts Substitutions & Modifications
Parts substitutions and modifications are allowed by authorized Delta Elektronika service personnel only. For repairs or
modifications the unit must be returned to a Delta Elektronika service facility.
Warning:
When the positive power output can exceed 60VDC in respect to the negative output, additional external
measures must be taken to ensure safety isolation of the power outputs and sense connections.
Warning:
When the negative power output of the unit can exceed 60VDC / 42.4Vpk in respect to ground, additional
external measures must be taken to ensure safety isolation of the power outputs and sense connections.
The standard LAN and Interlock connectors and optional interfaces are at ground level and can be considered
safe if the negative power output of the unit does not exceed 1000VDC / 707Vpk in respect to ground.

3 SIMULATION INTERFACE
1CONDENSATION
•During normal operation, humidity will not harm the interfaces, provided the air is not aggressive. The heat normally pro-
duced in the power supply will keep it dry.
•Avoid condensation inside the interfaces, break-down could be the result. Condensation can occur during a period the
power supply has been switched off (or operating at no load) and the ambient temperature is increasing. Always allow the
power supply to dry before switching it on again.
2TEMPERATURE & COOLING
•The storage temperature range is –40 to +85 °C.
•The operating temperature range is –20 to +50 °C.But this temperature range only holds when the air-intake and air-outlet
of the power supply are unobstructed and the temperature of the air-intake is not higher than +50 °C.
•When the power supply is mounted in a cabinet, please note that the temperature of the air-intake should be kept low and
avoid a short circuit in the airflow i.e. the hot air leaving the air-outlet
entering the air-intake again.
•Please note: a lower temperature extends the life of the interface.
3FIRMWARE
•Before hardware installation of the interface, check the firmware package is P0114 or higher. In the front menu, go to:
SYSTEM INFO -> UNIT-> VERSION.
•If an update is required, refer to the SM3300 unit manual how to do this.
4HARDWARE INSTALLATION
Warning! Never make connections to the Power Input, the Power Output or the Sense Connector when the SM3300 unit is
connected to the mains supply!
Safety covers are used to cover these in- and outputs.
INSERT INTERFACE IN THE UNIT
•Switch off the unit.
•Disconnect the unit from the mains supply.
•Wait for 3 minutes to allow internal capacitors to discharge.
•Select a none used slot at the rear side.
The Interface can be inserted in slot 2, 3 or 4. See figure 3 - 1.
•The simulation interface cannot be used in combination with an an-
alog interface. Please remove the analog interface if installed, be-
fore using the simulation interface
•Unscrew the 2 torx T10 screws and remove the slot cover.
•Insert the interface and place the 2 screws back to secure the inter-
face.
5UNIT CONFIGURATION
•The unit will automatically detect the new inserted interface.
•The interface icon will be shown in the display, see fig 3 - 2.
•For programming the voltage and/or current via the interface, set
the correct source for CV and CC respectively, see below example.
For example the interface is assembled in slot2.
To program the CV-settings via this interface, via the front menu go
to CONFIGURATION -> SOURCE -> Vsettings and set it to Slot2.
To program also the CC-settings via this interface, go to CONFIG-
URATION -> SOURCE -> Isettings and also set it to Slot2.
Instead of doing this via the Front Menu, the source can also be set
via the web interface or via Ethernet commands if the unit is
connected to the network via LAN.
•To configure the simulation interface, the power supply must be connected to the network via LAN.
6PHOTOVOLTAIC SIMULATION
6.1 CONFIGURATION PARAMETERS
•to simulate a photovoltaic curve some reference parameters are required. these parameters are often specified by manu-
facturers of photovoltaic panels. the parameters required for the simulation interface should be values under stc. stc speci-
fies a temperature of 25 °c and an irradiance of 1000 w/m2 with an air mass 1.5 (am1.5) spectrum. figure 3 - 3 shows an

6.3 TABLE MODE
•The simulation interface also supports a table mode. With this table mode it is possible to simulate a custom curve. Or sim-
ulate a photovoltaic curve existing of multiple panels in series where some panels are shaded. In table mode the simula-
tion module uses a table of 128 data points to program the current of the power supply.
•It is possible to calculate a partially shaded photovoltaic curve with the desktop application. The resulting table can be ex-
ported to a csv (comma separated value) file.
•Custom or calculated tables are programmable via the desktop application.
6.4 DESKTOP APPLICATION
•All the parameters required for photovoltaic simulation can be configured using the desktop application which is supplied
on a CD with the simulation module. The CD can also be downloaded from http://www.delta-elektronika.nl/
•When the application is started, it will show the welcome screen, it will query a list of power supplies with a simulation inter-
face installed. Select the power supply form the drop down list and connect. Or enter a IP address and connect. Select the
desired simulation type after this and click start, after which the corresponding application will start. Figure 3 - 4 shows the
“welcome screen”.
•In the photovoltaic simulation the parameters for the photovoltaic simulation can be configured. The application also ren-
ders the photovoltaic curve calculated with the entered values. The application reads the voltage and current measure-
ments of the power supply and displays these in the graph. Figure 3 - 5 shows the “Photovoltaic Simulation” application.
•To calculate a new photovoltaic curve, enter all required parameters and click ‘Calculate’. If one of the parameters
changes in the window, the calculation will automatically take place.
•The simulation module in the connected power supply stores the parameters in its memory, to get these parameters click
‘Load’. When you accept the following dialog, the parameters from the simulation module are filled in the application.
•To store new parameters in the simulation module, click ‘Write’. The new parameters are now stored in the simulation
module.
•The simulation mode can be changed under the Tools section of the menu bar. In the ‘Photovoltaic Simulation’ window
these modes are ‘Single Panel’, ‘Multiple Panels’ and ‘Dynamic efficiency’. When the simulation mode is changed, the out-
put of the power supply is switched off.
•In ‘Single Panel’ mode, it is possible to simulate a single photovoltaic curve.
•In ‘Multiple Panel’ mode, calculation of an array of panels is possible.
•In ‘Dynamic efficiency’ mode, it is possible to start a dynamic efficiency test.
•Be sure to store the new reference parameters and dynamic test settings to the simulation module before starting the
dynamic efficiency test.

7TABLE SIMULATION
•The simulation interface can simulate a custom curve based on a table as described in chapter . A separate application is
available specifically for this mode.
•With this application it is possible to manage, load and write tables from and to the simulation interface.
•The application can read ‘csv’ files. To use this feature please use the following format:
o The columns must be separated by a comma (,).
o The rows must be separated by a new line.
o The first row must contain Index, Voltage and Current in that order.
o The first index must contain zero for either the voltage- or the current settings, where the last index must contain
zero for the opposite.
o The voltage values can only increment or decrement in value for the whole table.
o See the following example:
Index, Voltage, Current

8INTERNAL RESISTANCE SIMULATION
•The simulation interface can simulate an internal resistance with a maximum value depending on the type of power sup-
ply.
•The settings for the internal resistance can be configured trough the web interface. Within the interfaces page.
•The internal resistance simulation is very sensitive to high capacitive loads. A slow setting is available in the web interface
if the simulation is unstable.
•The internal resistance simulation is a correction of any other programming source. For example you can set the voltage
and current with the front knobs, set an internal resistance value trough the web interface, and the simulation interface au-
tomatically corrects the output voltage.
9LEADLESS SENSING SIMULATION
•The simulation interface can automatically compensate for voltage drops over the leads without using sense leads. This
simulation type has three different modes:
oCalculate resistance: In this mode the resistance of the cable is calculated by means of the materials electrical
resistivity, length and the cross sectional area.
oMeasure voltage drop: In this mode the user must measure the voltage on the output terminals of the power supply,
the voltage on the terminals of the load, and the corresponding current.
oMeasure resistance: In this mode the user must measure the resistance of the leads.
•All these operating modes are limited by the maximum configurable resistance as specified.
•The settings for the leadless sensing simulation can be configured trough the web interface. Within the interfaces page.
•The leadless sensing simulation is a correction on any other programming source. For example you can set the voltage
and current with the front knobs, set a leadless sensing resistance value trough the web interface, and the simulation inter-
face automatically corrects the output voltage.
10 FOLDBACK CURRENT SIMULATION
•The simulation interface can simulate foldback current limiting behavior to provide a higher level of protection for DUT’s. In
foldback current limiting the power supply will fold back, after being a specified time in constant current mode, to a prede-
fined current setting. Figure 3 - 6 shows an example of this current limit behavior.
•The foldback current simulation can also be used to simulate a foldforward current limit.

4 ISOLATED CONTACTS
1CONDENSATION
•During normal operation, humidity will not harm the interfaces,
provided the air is not aggressive. The heat normally produced in
the power supply will keep it dry.
•Avoid condensation inside the interfaces, break-down could be
the result. Condensation can occur during a period the power
supply has been switched off (or operating at no load) and the am-
bient temperature is increasing. Always allow the power supply to
dry before switching it on again.
2TEMPERATURE & COOLING
•The storage temperature range is –40 to +85 °C.
•The operating temperature range is –20 to +50 °C.But this tem-
perature range only holds when the air-intake and air-outlet of the
power supply are unobstructed and the temperature of the air-in-
take is not higher than +50 °C.
•When the power supply is mounted in a cabinet, please note that
the temperature of the air-intake should be kept low and avoid a
short circuit in the airflow i.e. the hot air leaving the air-outlet
entering the air-intake again.
•Please note: a lower temperature extends the life of the interface.
3FIRMWARE
•Before hardware installation of the interface, check the firmware
package is P0114 or higher. In the front menu, go to:

5UNIT CONFIGURATION
•The unit will automatically detect the new inserted interface.
•The interface icon will be shown in the display, see fig 5 - 4.
•For programming the voltage and/or current via the interface, set
the correct source for CV and CC respectively, see below exam-
ple:
For example the interface is mounted in slot2.
To program the CV-settings via this interface, via the front menu
go to CONFIGURATION -> SOURCE -> Vsettings and set it to
Slot2.
To program also the CC-settings via this interface, go to CON-
FIGURATION -> SOURCE -> Isettings and also set it to Slot2.
Instead of doing this via the Front Menu, the source can also be
set via the web interface or via Ethernet commands if the unit is
connected to the network via LAN.
6SERIAL PROGRAMMING
•The unit can be programmed by using the serial programming
commands. See table 4.1 for an overview of the available com-
mands.
•To start, first the command "CH
n " must be executed to activate
the interface by setting its channel number (address).
The variable
n is a number between 1...32. For example "CH 1".
•The command "CH?" queries the channel of the active serial
interface.
•For more details about the commands in table 4.1, refer to chap-
ter 5 of the programming manual for Ethernet & Sequencer.
The manual is stored inside every SM3300 unit and can be down-
loaded via the web interface. It can also be downloaded from
www.DeltaPowerSupplies.com.
7PROGRAMMING SPEED
•Programming from a low to a high output voltage is nearly load
independent.
•Programming down to a low voltage takes more time on lighter
loads. This is caused by the output capacitors, which can only be
discharged by the load because the power supply cannot sink
current.
•With the optional Power Sink, also the programming down speed
is nearly load independent.
•With optional high speed programming, the rise and fall time is
5 to 25 times faster. Note that with this option. the output ripple is
higher.
8MONITORING VIA SERIAL INTERFACE
•Via the programming command "MEASURE:" the voltage,
current or power can be monitored.
See the manual 'Ethernet & Sequencer Programming SM3300'
for details.
•Note: on a pulsating load, the current and power monitoring will
not exactly match the output current and power. This is mainly
caused by the current through the output capacitors.
9TROUBLE SHOOTING
•Check the programming source is set to the correct slot.
•Check the output is switched ON, the Interlock is connected and
Remote ShutDown is low.
•The first programming command must be "CH n" otherwise the in-
terface will not be activated.
•Check that the communication is working; "*IDN?" must return a
value. Ensure to end the query with the termination character LF.
(LF = 0x0Ah in ASCII)
•Note: the serial interface uses the '.' (dot) as the decimal symbol
and not the ',' (comma). Check if your program is using the set-
tings in Microsoft Windows® regional settings.
•Either change your program to specifically use the '.' or else
change the decimal symbol to '.' in your regional settings (from the
control panel).

•Check that the power supply's output is not limited.
Consult the SM3300 manual about adjusting the limit settings.
•Check that both values for CV and CC are not zero.
It is not possible to program a voltage when the current control is
set to zero and vice versa.
•Check that the power supply is in the required mode (CV or CC).
When programming a voltage, the unit must be in CV-mode,
when programming a current, the unit must be in CC-mode.
