1.Introduction
This chapter describes the general characteristics and main features of the F1K5-
DISS power dissipation unit.
1.1 F1K5-DISS Overview
The FAST-PS-1K5 by CAEN ELS is an independent current- or voltage-
controlled digital bipolar power supply module. Standalone, the FAST-PS-1K5 is a
bipolar power converter able to work in the positive current/positive voltage and
negative current/negative voltage quadrants only continuously.
The F1K5-DISS unit adds current/voltage sinking capabilities to the system so
that a FAST-PS-1K5 together with a F1K5-DISS becomes a full 4-quadrant system
capable not only sourcing but also sinking up to 1.500 W.
There are two commercially available models for the F1K5-DISS unit that can be
matched to specific models of the FAST-PS-1K5 power unit:

FAST4R050030

±30 V
FAST-PS-1K5 50-30
Table 1: F1K5-DISS models
The F1K5-DISS module is compact and fits in a single 19-inch 1U standard
crate. The whole system together with a FAST-PS-1K5 fits in a 19” - 3U slot.

2.Installation
This chapter contains the main instructions for initial inspection and preparation
for use.
2.1 Preparation for Use
In order to put the system into operation, the power supply must be connected to
an appropriate AC source. The AC source voltage should be within the power supply
specification. Do not apply power before reading this manual. Table 2 Error!
Reference source not found.lists the basic setup procedure. Follow the instructions in
the given sequence to prepare the power supply for use.

2.2 Initial Inspection
Prior to shipment, this F1K5-DISS unit was inspected and found free of
mechanical or electrical defects. Upon unpacking of the power supply, inspect for any
damage which may have occurred in transit.
The inspection should confirm that there is no exterior damage to the power
supply such as broken switches or connectors and that all panels and display are not
scratched or cracked. Keep all packing material until the inspection has been completed.
If damage is detected, compile the RMA form available to the CAEN ELS web site.

2.3 Mounting
The FAST-PS-1K5 & F1K5-DISS system can be used either as a desktop unit or
as a rack-mount device since the unit form factor is designed to be installed in a standard
3U 19-inch cabinet.
This system is fan cooled, the air intake is at the front panel
and the exhaust is at the rear panel. Upon installation allow
cooling air to reach the front panel ventilation inlets. Allow
minimum 10 cm of unrestricted air space at the front and 20
cm on the rear of the unit.
Rack Mounting
The FAST-PS-1K5 & F1K5-DISS system is designed to fit in a standard 19”
equipment rack.
Use a support bar to provide adequate support for the power
supply.
Desktop Use
The FAST-PS-1K5 & F1K5-DISS system can be used as desktop unit but every
precaution must be used to avoid touching the output connectors because of the high
energy source.
CAUTION

WARNING

F1K5-DISS –User’s Manual

User shall protect output contacts by placing the FAST-PS-
1K5 & F1K5-DISS system inside a closed rack or by
restricting the access to the back side.
Thermal Management
F1K5-DISS converts electrical into thermal energy, considerable amount of heat
is generated. This fact must be taken into consideration when installing the system. Fans
cool the dissipation element by drawing air from front side and exhausting it out the
back, therefore minimum 10 cm of unrestricted air space at the front and 20 cm on the
back of the unit must be provided.
If specific application requires high power dissipation for long periods (> 800 W;
> 10 min) it is recommended to install FAST-PS-1K5 and F1K5-DISS with 1U of
clearance in between to mitigate heating problems and using blanking panels to prevent
mixing hot and cold air. Proper equipment rack ventilation shall be provided to reduce
ambient temperature not exceed 45 °C on the front of the units.
Do not touch the hot surfaces. The temperature of the back
and top-right surfaces may be high when the unit is operating
at high power.
2.4 F1K5-DISS connection
Turn off the AC input power before making or changing any
rear panel connection. Ensure that all connections are
securely tightened before applying power. There is a
potential shock hazard when using a power supply with a
rated output greater than 60 V

Power Connection
It is recommended to use original cables that are contained with the unit. If
custom longer connection is required keep wire size of main power connection at 16
mm2(AWG 6) and not longer than 1m. Strip wires insulation back 15 mm and push
them straight into the power plug and screw them tightly. Be sure that they fit well and
make a good contact.
Connect main power cable to DISSIPATIVE UNIT connector on FAST-PS-1K5
and to FAST-PS-1K5 connector on dissipation unit. Secure cable assembly with
connectors screws on both ends.
Figure 1: “Power cable”connection
Status Cable Connection
Connect the supplied coaxial cable to STATUS BNC connector on F1K5-DISS
side and AUX2 BNC connector on FAST-PS-1K5 side.

2.5 FAST-PS-1K5 Connections
For installation and connection instructions refer to FAST-PS-1K5 User’s
Manual, chapter 2.
2.6 FAST-PS-1K5 Configuration
FAST-PS-1K5 in standalone configuration has 100 W of negative power. Even
if dissipation unit is connected to main power converter 100 W limit is still active and
system will go in fault if this limit is exceeded. To achievefull current sinking capability
when using dissipative unit this option must be enabled in FAST-PS-1K5 configuration.
Power converters purchased together with F1K5-DISS dissipation unit have this option
already enabled by default.
To enable (or disable) full current sinking capability use FAST-PS-1K5’s web
server interface. Under CONFIG tab select INTERNAL MEMORY. Set Value of ID 54
(Dissipative enabled on AUX2 at start-up) to “1”. For more information on
configuration refer to Remote Control Manual.
Whenever changing this parameter FAST-PS-1K5 must be power-cycled for
new value to be valid.
2.7 Front Panel LED Indicator
The F1K5-DISS has front panel LED indicator as shown in the Figure 3.

The front panel indicator and its behaviour is outlined in the following table:

Table 3 –Front-panel LED behaviour
Status LED in green indicates the module is connected properly and fully
operational. Solid red at power-on means that wrong FAST-PS-1K5 was detected.
LED will flash orange to indicate warnings; the module is sinking current when
flashing interval is short, warning may be for the following reasons: high power, high
temperature or fan malfunction. When interval is long the module is not active, warning
indicates fan malfunction or high temperature of the module caused by just finished
power dissipation.
Solid red is reserved for major errors: thermal overload, too high input current,
too high input power or hardware failure. In all this cases dissipation unit reports error
to FAST-PS-1K5 which then disables its output and activates crowbar function to
prevent potential or further damage.
When in firmware update mode LED will be changing colours. FAST-PS-1K5
will automatically disable its output.

3.Firmware Update
If a firmware update is necessary, this can be done using Firmware-Update.exe
utility. It requires the C run-time libraries (CRT), if not already installed you can do it
by running “vcredist_x86.exe” which can be found in the same directory ad firmware
update utility on supplied USB Flash drive.
3.1 Firmware Update Procedure
Save the file to your computer and note the directory where the file is saved. A
firmware update is a file with a “.hex”extension. Preferably save it in the same directory
of Firmware-Update.exe utility.
To perform the update F1K5-DISS must be connected to FAST-PS-1K5 which
must be switched on with its output disabled. Never try to update if FAST-PS-1K5
output is not disabled.
Connect the computer's USB port to the F1K5-DISS’s USB-B port with a USB
cable.
Using Windows Device Manager identify COM port number - locate Ports (COM
& LPT) in the list, expand it and check for USB Serial Port. Open Command Prompt
(CMD) and change directory to folder where Firmware-Update.exe resides.
Launch update utility with following parameters:
•a <file> firmware update filename with path - mandatory
•p COM<num> e.g. COM9 - mandatory
•b <num> baud rate –optional
Firmware update takes ~30 seconds with default baud rate. After successful
completion front panel status led turns blinking green and the module is ready to use.
