1.Introduction
1.1 User Manual Content
This manual contains basic operating instructions and installation instructions for
the FAST-PS-M monopolar power supplies; information contained in this manual refer
both to the standard and custom FAST-PS-M models.
In this manual only the local control of the power supply is covered, while for the
remote control interface the “VISUAL manual” is the reference. The expert user can
then refer to the “Remote Control Manual” in order to use the dedicated programming
language of the power supplies.
1.2 FAST-PS-M Overview
High performances, high efficiency, high stability, easiness of configuration and
maintenance are the key features of the FAST-PS-M power supply series.
The FAST-PS-M is an independent current- or voltage-controlled digital bipolar
power supply module. There are available different models with different current and
voltage ranges:

Table 1: FAST-PS-M models
CAEN ELS could produce also customized FAST-PS-M with different current and
voltage ranges based on special request; if this manual is ship with a custom FAST-PS-
M different form the mentioned in Table 1 refer to Appendix A for the parameter
differing from standard model.
The FAST-PS-M module is compact and fits in a single 19-inch 1U standard
crate. The power unit implements a completely digital control loop with a Pulse Width
Modulation (PWM) generation technique that allows to adapt the system to any load
condition.
The control board houses a dedicated FPGA with integrated dual-core ARM
CPU. The loop regulation task is performed directly by the FPGA logic, in order to

FAST-PS-M –User’s Manual
11
have high performance and deterministic loop control. On the ARM CPU an embedded
Linux OS is installed, with the task to supervise all process as communication,
diagnostics and local interface handling.
Remote communication is guaranteed by means of an Ethernet 10/100/1000
autosensing socket present on the front panel of the power unit. The power supply can
be also monitored and controlled via a navigation switch and a graphic high resolution
color display featuring user-friendly menus.
In addition to the standard Ethernet interface it is possible to communicate with
the unit using the SFP-ports on the front panel. This interface allows to communicate
with the unit using a proprietary packet structure with a very high update rate (more
than 10 kHz). These ports are connected directly to the FPGA logic and so the given
packet is elaborated directly by the hardware logic.
This approach eliminates the software stratification that manages the packet and
the computational time is smaller and deterministic, allowing a very high update rate of
the setpoint, giving the user more flexibility and excellent rates for the digital control
of the power supply.
1.3 FAST-PS-M at a glance
The FAST-PS-M system is composed by a single 19-inch 1U crate. The FAST-
PS-M unit and its I/O connections are presented in Figure 1 (front view) and Figure 2
(rear view).
Figure 1: FAST-PS-M front view
On the front side of the FAST-PS-M unit are placed: a power switch, a colour
graphic display with navigation switch for the local control of the module, three
communication sockets (2 SFPs and one Ethernet ports), four status LEDs and one USB
device connector.

Figure 2: FAST-PS-M rear view
On the rear side of the unit are placed: AC power line input, fuse holder, the
output connection, the D-Sub 15 Female Pin I/O connector. From units of all models
with SN ending in x010 and later, a separate connector for the voltage remote sensing
is also present below the I/O connector.
The FAST-PS-M 3030, as it carries up to 30 Amperes only, it is provided with 2 x
WGKV 10/Z SW output connectors, instead of metal bars:
Some models can mount one or two BNC connectors reserved for additional
features of the power supply.

1.4 Modes of Operation
The FAST-PS-M system has multiple features and multiple configurations that
allow using the unit for a very widespread topology of applications.
A brief summary of the basic configurations that the unit is able to handle are
hereafter presented.
Regulation Mode
The FAST-PS-M can be used as current-controlled or voltage-controlled
monopolar units. The regulation types are:
•C.C. mode: it is the Constant Current regulation mode. The power supply
regulates the output current set by the user;
•C.V. mode: it is the Constant Voltage regulation mode. The power supply
regulates the output voltage set by the user.
In C.V. mode it is possible to use the remote sensing terminals that allow
regulating the output voltage directly on the load thus compensating the voltage drops
on the output cables. The maximum voltage drop that the power supply is able to
compensate is of 0.5V.
Local, Remote, Fast-Interface Control Mode
The FAST-PS unit can be controlled in three main different ways, hereafter listed:
•LOCAL control: the unit can be controlled directly via the front panel color
display and the navigation switch. When the unit is set in LOCAL mode it is
possible to perform readings and monitor from the remote interface but any
setting command is denied;
•REMOTE control: the unit is controlled via the TCP-IP Ethernet interface.
The setting and control of the unit can be performed exclusively via this
interface while monitoring is still possible from the local display. Please refer
to “Remote Control Manual” and “VISUAL Manual” for this feature;
•FAST-INTERFACE control: this interface allows controlling the unit via a
proprietary protocol over the SFP/SFP+ interfaces (optical or electrical) and
it is meant to be used for very fast applications. Update rates of more than 10
kHz are reachable using this communication channel. Please refer to
“Operation Manual” for this feature;

FAST-PS-M –User’s Manual
14
Update Mode
The current or voltage setting of the unit can also be performed in four different
modes:
•NORMAL: the update of the set-point (current or voltage, depending on the
operation mode) is performed as soon as a new set-point is received via the
remote, local or fast interfaces;
•WAVEFORM: the update of the set-point is performed on a specific timing
(defined as a “waveform” attribute, more information on the Waveform
section) and it is done internally;
•TRIGGER: the set-point is updated by an external event –i.e. a hardware
trigger coming from the rear BNC connector. Please note that this mode of
operation is obtainable only on the units that have the external trigger input
connector installed (ordering option –factory configurable);
•ANALOG INPUT: the unit is controlled by an external signal that is fed to
the rear BNC connector. The unit acts as a C.C. or C.V. generator depending
on the pre-set Regulation Mode. This option is only available in units that
have been factory configured (ordering option).
Please note that the last two Update Modes of operation are available only in
models that have been factory configured at the time of purchase to have the Trigger
Input and/or the Analog Control Input features.

2.Power Supply Main Features
The features listed in this chapter are common to the FAST-PS-M family and can be
regarded as the basic features of this power supplies family.
2.1 Connectors
Three different types of connection are present in FAST-PS-M power supplies:
power cables connector (bus-bars), I/O connectors and remote sensing connectors.
Analog control input and trigger input are on BNC connectors which are optional and
needs to be added at the time of the ordering.
Power Cables Connectors
The load needs to be connected to the output connector placed on the rear panel
of the unit as shown in Figure 3.
Figure 3: Output Connector
The symbols “+” and “-”on the rear panel indicate the positive and negative
polarity of the terminal respectively.

FAST-PS-M –User’s Manual
16
Power Cables Connectors for the FAST-PS-M 3030
The load needs to be connected to the output connector placed on the rear panel
of the unit as shown in Figure 3. This type of connector offers a convenient and reliable
form of connection; it is suggested to connect the wire directly to the connector. The
suggested cross-sectional area of the cables is rated to be from AWG 24 to AWG 6.
Figure 4: Output Connector
The symbols “+” and “-” on the rear panel indicate the positive and negative
polarity of the terminal respectively.

FAST-PS-M –User’s Manual

I/O Connectors
The FAST-PS-M module has two configurable dry-contact input interlocks and
output status signals that are directly available on the D-Sub 15 Pin Female connector
on the rear panel (Figure 5).
A mating connector, a standard D-Sub 15 Pin Male type, can be installed in
order to use/access these available signals.
Figure 5: I/O Connector
The pin index of the D-Sub 15 rear connector is summarized in the following
table:

The magnetic relay provides the output status of the power module: when the
module is ON, the Normally Closed contact (NC-TAP) switch opens and vice-versa.
The absolute maximum current that can be sunk by the output status magnetic relays
(pins #5, #6 and #13) is 200 mA.
The interlock pins are galvanically isolated from ground and outputs terminal,
nevertheless the absolute maximum voltage, referred to ground, that pins can sustain is
48V. The two interlocks inputs have their own return connection. The interlock is
hardware-activated when the input pin and its corresponding return pin are shorted. Do
not apply voltage between any input interlock and its corresponding return.
The configurability of the FAST-PS-M series allows users to decide what
interlock are enabled or not, set the interlock “trip” level (i.e. low or high), the time of
intervention (the time that an interlock signal has to be at the trip level before generating
a fault condition) and an associated interlock name. These advanced features are
discussed in the “Remote Control Manual”. The interlocks are disabled by default.
Remote Sensing
From FAST-PS-M of any model with SN (Serial Number) ending with x10 and
later –i.e. x11, x12, etc. –there is a different voltage-sensing connector on the rear
panel that allows using the voltage sensing feature especially when using the power
supply in C.V. mode. Connector is shown in Figure 6.
Figure 6: Remote Sensing Connector
The FAST-PS-M can be used in constant voltage (CV) mode and two remote
sensing terminals are present on the corresponding connector on the rear panel:
-VSENSE + on pin #1: +S;
-VOUT + on pin #2: +;
-VOUT - on pin #3: –;
-VSENSE –on pin #4: -S.
Pin #1
Pin #4

FAST-PS-M –User’s Manual
19
By using these two “sensing” pins it is possible to sense the output voltage
directly on the load, thus recovering possible voltage drops on the output cables up to
0.5V.
It is strongly suggested to use twisted cables when using the remote sensing
feature in order to minimize possible noise pick-up.
The FAST-PS-M is shipped with a mating connector for the remote sensing that
short-circuits the +S and + pins and the –S and –pins respectively. This configuration
performs the remote sensing directly at the output connector of the power unit. Leaving
+S and –S pins disconnected will make the power supply sense the output voltage
directly at the output terminal connections. When using the remote sensing feature leave
pins #2 (+) and #3 (–) disconnected.
In order to perform remote sensing at different points –e.g. the load terminals
–it would be necessary to connect Pin #1 and Pin #4 as in Figure 7:
Figure 7: Example of Remote Sensing
2.2 Options
The FAST-PS-M can be configured with options that are factory-configured and
can be found on the rear panel in places of connectors A and B.
The standard version of the FAST-PS-M, on the rear panel, is as shown in the

Description
FASTPSACINXA
Analog Control Input (±10V) on BNC connector - optional
FASTPSTRINXA
Trigger Input on BNC connector - optional
A brief description of the two options is presented hereafter.
Analog Control Input
An input that allows the FAST-PS-M to be controlled as an “amplifier” is
provided on the rear panel on a BNC connector on the “A” socket. This input is labelled
as “AN CTRL”.
This input accepts signals ranging from 0V to +10V and generates an output
which is proportional to the input signal, meaning a 0 for a 0V input and Full-Scale for
a +10V input. An example of the relation between the analog input signal and the output
(can be either current or voltage, depending on the Regulation mode) is shown in Figure
10.
Figure 10: AN CTRL vs OUTPUT dependence
Please note that the bandwidth of the analog control input is internally limited
to 1 kHz
