defective due to workmanship or materials and has not been caused by mishandling, negligence on behalf of the User,
accident or any abnormal conditions or operations.

CAEN declines all responsibility for damages or injuries caused by an improper use of the Modules due to negligence on

Disposal of the Product

The product must never be dumped in the Municipal Waste. Please check your local regulations

Made In Italy

: We stress the fact that all the boards are made in Italy because in this globalized world, where getting

the lowest possible price for products sometimes translates into poor pay and working conditions for the people who
make them, at least you know that who made your board was reasonably paid and worked in a safe environment. (this
obviously applies only to the boards marked "Made in Italy", we cannot attest to the manufacturing process of "third
party" boards).

HV outputs are delivered through SHV connectors.

“Mixed” versions have two positive and two negative

channels.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel with 1
V/s steps. The module features 16bit ISET/IMON resolution. Optionally, the modules can be ordered with
current monitor resolution extended by 10x in a Lower range (selectable via software).
Safety features include:

•

OVERVOLTAGE and UNDERVOLTAGE warning when the output voltage differs from the programmed
value

•

OVERCURRENT detection: if a channel tries to draw a current larger than its programmed limit, it is
turned off

•

Channels can be enabled or disabled through the Interlock logic

•

Channels individually enabled via front panel jumpers (passive or active mode available)

Functional parameters can be programmed and monitored via USB and Ethernet (external PC required),
supported OS: Windows 7 or later; Linux kernel Rel. 2.4 or later.

Technical specifications

Packaging

The DT55xxE unit is a Desktop module housed in a 154x50x164 mm

alloy box. The kit includes:

•

DT55xxE desktop power supply unit

•

External AC/DC power supply with separate power cord

•

USB cable

•

10BASE-T Ethernet cable

Power requirements

The module is powered by the external AC/DC stabilized power supply included in the delivered kit
(Switchbox Model FRA045-S12-4; see specifications in table p.5)

Note.:

Using a different power supply source, like battery or linear type, it is recommended the source to

provide +12V and, at least, 2.5A; the power jack is a 2.1mm type, a suitable cable is the RS 656-3816 type
(or similar).

Alarm signal

As an Alarm condition is detected (see p.) pins 2 and 3 (- and +) are closed; the contact can be used to
switch an external device supplied by an external source, otherwise the VB and GND references can be
used to provide a TTL compatible level on pin 2 and 3.

In the first case (externally supplied device) the maximum allowed ratings are:

•

Maximum voltage between + and -: 12V

•

Maximum sink current across + and -: 100mA

In the latter case, to produce a TTL compatible Alarm Out, pin 3 (+) must be connected with pin 4 (VB) and
pin 1 (GND) with pin 2 (-); see the diagram below:

Fig. 8: ALARM TTL configured

Interlock signal

With reference to diagram of the Interlock input shown above, the diode is part of opto-coupler stage.
Interlock means that channels are hardware disabled. The interlock operation is as follows:

GECO2020

CAEN GECO2020 is a graphical application that allows to control the DT55xxE HV Desktop Power Supplies
(and all other CAEN Power Supplies). Once the DT55xxE is correctly installed, download and install the

GECO2020 software package related to your OS; follow the instructions in the GECO2020 User manual

CAEN HV Wrapper

CAEN HV Wrapper is a library, available either as a set of ANSI C functions or LabVI

EW™ VI’s. Such

set

provides the software developer an unified software interface for the control of CAEN Power Supplies.
This is a low level application in which the writing of the Control SW is assigned to the user. It contains a
generic software interface independent by the Power Supply models and by the communication path used
to exchange data with them.

CAEN HV Wrapper is logically located between an higher level application, such as GECO2020, and the
lower layer software libraries.

Module access

The module is provided with a USB2.0 compliant interface and Ethernet Port (TCP/IP).
For link connection, refer to instructions given at page 10.
CAEN provides the CAEN GECO2020 Control Software that allows a friendly remote management of all

Unit’s functional parameters (see

www.caen.it software support page); anyway, the connection can be

performed also via VT emulators, we suggest to use Tera Term (see https://ttssh2.osdn.jp/index.html.en)

USB

Launch the terminal emulator (we suggest using
Tera Term), select the serial communication link
and set the virtual communication port
associated to the module. Select USB connection
and the used port number; set port as follows

baud rate 9600

Data bits: 8

Parity: none

stop bit: 1

Flow control: none

At first Power On the module is configured with default static IP (factory setting); such IP can be updated

using the “arrows” to select the fields, typing the new values and confirming with <Enter>.

Type S to save the new setting in the EEPROM and go back to Main Menu.

The new setting will become active at next Power On; if a DHCP Server is available, then the module can
be enabled or disabled as DHCP client; type S to save the new setting in the EEPROM and go back to Main
Menu: the DHCP server will automatically assign a new IP to the module at next Power On.
