SAFETY INSTRUCTIONS - SM15K-series
1.1
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. Delta Elektronika shall not be
liable for user’s failure to comply with these requirements.
1.2
Installation Category
The Delta Elektronika power supplies have been evaluated to installation category II (Over voltage category II).
1.3
Grounding of Mains Terminals (AC Power Terminals)
This product is a safety Class 1 unit. To minimize shock hazard, the unit must be connected to the AC Power Supply
mains through a four conductor power cable, with the ground wire firmly connected to an electrical ground (safety
ground) at the power outlet.
For units designed to be hard-wired to the mains supply, 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.
1.4
Grounding of DC Power Terminals
If the DC power terminal of a unit is specified to sink or source to a maximum of 60VDC, and either the 'minus' or 'plus'
DC power terminal is grounded, the voltage on the DC power terminals and sense connections can be considered safe.
Caution 1: If a low voltage unit has both DC power terminals floating, or if the terminals are in series with an external
high AC or DC voltage, the 'minus' DC power terminal 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
a high voltage unit! Wrong operation, a programming error or an external defect can result in an unsafe high DC output
voltage.
For more information and schematics regards Grounding & Safety, see application note "Safe operation of a power
supply" on the Delta Elektronika website.
1.5
Danger of electrical shock
Touching the contacts of the mains plug or wires directly after disconnecting from the mains, can cause an electrical
shock. And there can still be a dangerous voltage between one of the DC power terminals and the PE because of
charged X-capacitors. This can also happen when the DC power output is switched off, but the unit is still switched on!
Therefore never touch PE and one of the DC power terminals at the same time.
1.6
Connection to mains supply
Either connect to the mains supply permanently or via an industrial type plug, complying with IEC 60309.
"Permanently connected equipment" or "Pluggable equipment type B".
1.7
Fuses
Fuses must be changed by authorized Delta Elektronika service personnel only, for continued protection against risk of
fire.
1.8
AC Input Ratings
Do not use an AC Supply which exceeds the AC input voltage and frequency rating of this unit. The AC input voltage and
frequency rating of the Delta Elektronika power supply series are stated in the accompanying datasheet.
1.9

SICHERHEITSHINWEISE - SM15K-series
2.1
Vorsicht
Die folgenden Sicherheitsvorkehrungen müssen in allen Betriebs-, Service- und Reparaturphasen dieses Geräts befolgt
werden. Die Nichteinhaltung der Sicherheitsvorkehrungen oder Warnungen in diesem Dokument verstößt gegen die
Sicherheitsstandards im Hinblick auf Bauart, Produktion und vorgesehene Nutzung dieses Geräts und kann die
eingebauten Schutzvorrichtungen beschädigen. Delta Elektronika haftet nicht dafür, wenn der Nutzer diesen
Anforderungen nicht nachkommt.
2.2
Installationskategorie
Die Stromversorgungen von Delta Elektronika wurden der Installationskategorie II (Überspannungskategorie II)
zugeordnet.
2.3
Erdung der Netzanschlussklemmen (AC-Einspeiseklemmen)
Dieses Produkt ist ein Gerät der Sicherheitsklasse 1. Um die Gefahr eines elektrischen Schlags zu minimieren, muss das
Gerät mit einem Vierleiter-Stromkabel mit dem AC-Stromversorgungsnetz verbunden werden. Hierbei muss der
Schutzleiter fest mit einem elektrischen Erdungsanschluss (Schutzleiter) an der Stromquelle verbunden sein. Bei
Geräten, die fest mit dem Versorgungsnetz verdrahtet werden, muss die Schutzerdungsklemme mit dem
Sicherheitserdungsanschluss verbunden werden, bevor eine andere Verbindung hergestellt wird. Eine Unterbrechung
des Schutzleiters oder eine Trennung der Schutzerdungsklemme kann zu einem elektrischen Schlag führen, der zur
Verletzung von Personen führen kann.
2.4
Erdung der DC-Anschlussklemmen
Wenn die DC-Anschlussklemme eines Geräts dafür ausgelegt ist, maximal 60 VDC zu empfangen oder zu beziehen und
entweder die 'minus' oder 'plus' DC-Anschlussklemme geerdet ist, kann die Spannung auf den DC-Anschlussklemmen
und Sense-Verbindungen als sicher angesehen werden.
Warnung! Wenn die 'plus' DC-Anschlussklemme im Verhältnis zur 'minus' DC-Anschlussklemme 60 VDC
überschreiten kann, müssen zusätzliche externe Maßnahmen ergriffen werden, um die Sicherheitsisolation der DC-
Anschlussklemmen und Sense-Verbindungen sicherzustellen.
Warnung! Wenn die 'minus' DC-Anschlussklemme im Verhältnis zur Erdung 60 VDC/42,4 Vpk überschreiten kann,
müssen zusätzliche externe Maßnahmen ergriffen werden, um die Sicherheitsisolation der DC-Anschlussklemmen
und Sense-Verbindungen sicherzustellen.
Die standardmäßigen LAN-, USB- und Interlock-Verbinder sowie optionale Schnittstellen sind auf Erdpotential und
können als sicher angesehen werden, wenn die 'minus' DC-Anschlussklemme des Geräts im Verhältnis zur Erdung
1000 VDC/707 Vpk nicht überschreitet für SM70-CP-450, SM210-CP-150 und SM500-CP-90, oder 1500VDC /
1060Vpk im Verhältnis zur PE für SM1500-CP-30.
Vorsicht 1: Falls beide DC-Anschlussklemmen eines Niederspannungsgerätes potentialfrei sind oder falls die DC-
Klemmen in Reihe mit einer externen AC- oder DC-Hochspannung geschaltet sind, kann die 'minus' DC- DC-
Anschlussklemme den sicheren Wert in Bezug auf die Erdung wie in der Warnung oben spezifiziert überschreiten.
Vorsicht 2: Obwohl ein Hochspannungsgerät mit einer sicheren Spannung unter 60 VDC betrieben wird, muss es zur
Sicherheit immer als Hochspannungsgerät angesehen werden! Falsche Bedienung, ein Programmierfehler oder ein
externer Fehler können zu einer unsicheren, hohen DC-Ausgangsspannung führen.
Für weitere Informationen und Schaltpläne hinsichtlich Erdung und Sicherheit, siehe den Applikationshinweis
'Safe operation of a power supply' auf der Delta Elektronika-Webseite.
2.5
Gefahr eines elektrischen Schlags
Das Berühren der Kontakte des Netzsteckers oder der Kabel direkt nach der Trennung vom Netz kann zu einem
elektrischen Schlag führen. Und aufgrund von geladenen X-Kondensatoren, kann gefährliches Potential zwischen 'plus'
oder ‘minus’ DC-Anschlussklemme und PE bestehen oder entstehen. Auch wenn die DC-Anschlussklemmen
ausgeschaltet sind, aber das Gerät noch eingeschaltet ist. Daher niemals gleichzeitig PE und einen der DC-
Anschlussklemmen berühren mit bloßen Händen.

o
The Master has a specific location in the system, depending
on the number of Slaves. Although in a later stage the
functional assigned is done via the unit's menu, it is required
to do the physical assignment first; at which location will the
Master be and at which the Slave(s).
o
For an uneven number of units, position the Master in
between an equal number of slaves.
o
For example in a set of 7 units, the upper 3 units must be
slaves, the master in position 4, and below it another 3
slaves.
o
For an even number of units, position the master in such a
way that under it there's 1 slave more than above it.
o
For example in a set of 8 units, the upper 3 units must be
slaves, then the master, and below it another 4 slaves.

SERIAL INTERFACE

Warning! carefully read the chapter "Safety Instructions" in
this manual before connecting or operating the unit!
5.1
CONDENSATION

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, to prevent break-
down. 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.
5.2
TEMPERATURE & 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 lifetime of the
interface.
5.3

UNIT 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, current and/or power via the
interface, set the correct source for CV, CC and CP
respectively, see below example:
o
For example the interface is mounted in slot2.
To program the CV-settings via this interface, via the front
menu go to CONFIGURATION -> PRG SOURCE ->
Vsettings and set it to Slot2.
To program the CC-settings via this interface, go to
CONFIGURATION -> PRG SOURCE -> Isettings and also
set it to Slot2.
To program the CP-settings via this interface, go to
CONFIGURATION -> PRG SOURCE -> Psettings 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.
5.6
SERIAL PROGRAMMING

The unit can be programmed by using the serial programming
commands. See table 5.1 for an overview of the available
commands.

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 5.1, refer to
chapter 5 of the Programming manual for Ethernet &
Sequencer.

The manual is stored inside every SM15K unit and can be
downloaded via the web interface. It can also be downloaded
from www.DeltaPowerSupplies.com.
5.7
PROGRAMMING SPEED

Programming from a low to a high output voltage is nearly
load independent.
5.8
MONITORING VIA SERIAL INTERFACE

Via the programming command "MEASURE:" the voltage,
current or power can be monitored.

Download the manual Ethernet & Sequencer Programming
SM15K for details.
5.9
TROUBLE 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

interface 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 settings 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 SM15K manual about adjusting the limit settings.

Check that ALL values for CV, CC and CP are not zero.

UNIT CONFIGURATION

The unit will automatically detect the new inserted interface.

The interface icon will be shown in the display, see fig 7 - 3.

For programming the voltage and/or current via the interface,
set the correct source for CV and CC respectively, see below
example.
o
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
CONFIGURATION -> 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.
7.6
ANALOG PROGRAMMING

The output voltage and current can be programmed by a
voltage in the range of 0 - 5V (default setting) or 0 - 10V,
proportionally to the full output voltage and current. (see
fig. 7 - 4).
o
Note that a voltage at the I-prog input (pin3), sets both the
value for CC+ and CC-. Thus applying +5V on pin3 on an
SM500-CP-90, sets CC+ to +90A, and CC- to –90A.
o
CC+ and CC- cannot be programmed to a different value via
the analog input.
o
A negative input voltage is ignored and sets CC+ and CC-
to 0A.

The range 0 - 5V or 0 - 10V can be selected by ethernet
command only. See ethernet programming manual for
further details.

Both have a protection circuit formed by a series resistor and
a parallel zener diode. The capacitor limits the speed to a
safe value. Note that the programming inputs are floating with
regards the power output.

Turn the output on again with the OUTPUT ON/OFF button.

To program the unit by current instead of voltage, simply use
a parallel resistor as a current to voltage converter. (see
fig. 7 - 5).

The front display will show the programmed values for CV
and CC.
7.7
ANALOG MONITORING

The monitor outputs give a voltage in the range of 0 - 5V or
0 - 10V, proportional to the output current or voltage. The
output current can easily be measured using the I-monitor
(see fig. 7 - 6).

The range 0 - 5V or 0 - 10V can be selected by ethernet
command only. See ethernet programming manual for further
details.

Note that the monitor outputs are floating with regards the
power output (similar to signals from the ISO AMP).

The monitor outputs are buffered with op-amps and protected
with series resistors and parallel zener diodes.

The table in the interface datasheet shows the impedance
levels of the monitoring outputs.

The monitoring outputs can drive a meter directly (fig. 7 - 6).

Note: on a pulsating load, the current monitor will not exactly
match the output current. This is mainly caused by the current
through the output capacitors.
7.8
STATUS SIGNALS

The status outputs have a separate Ø-connection (pin 8) to
avoid unwanted offsets in the programming.

All the status outputs are logic outputs. Logic "0" means the
output is 0 V, logic "1" means the output is 5 V. This makes it
possible to drive directly: an opto-coupler, a TTL gate or a
CMOS gate.

fig 7 - 8.

It is also possible to use a relay contact or a switch to shut the
unit down (see fig. 7 - 9).

In standby mode the power supply consumes very little
power.

Note: also via Eth or other interfaces RSD can be activated.
7.10
