CAEN will repair or replace any product within the guarantee period if the Guarantor declares that the product is
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
behalf of the User. It is strongly recommended to read thoroughly the CAEN User's Manual before any kind of operation.

Disposal of the Product The product must never be dumped in the Municipal Waste. Please check your local regulations
for disposal of electronics products.
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).

Positive
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.

2. Technical specifications
Packaging
The DT55xxE unit is a Desktop module housed in a 154x50x164 mm3 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).

HV OUT
HV Channel Output; Mod. SHV RADIALL R317580; Impedance: 50 Ohm; Frequency range: 0 –
2 GHz; VSWR: <1.20 + 0.3 F (GHz) – (plug and jack); Test voltage: 10kV DC – 1mn (unmated
connectors); Ratings: 12kV DC – 1mn (mated pairs); Current rating: 10 A
WARNING! These connectors produce extremely hazardous high voltages at a potentially
lethal current level; never connect or disconnect the HV OUT connector with the power
ON/OFF switch ON; always switch power OFF and wait at least 30s before connecting or
disconnecting HV cables.
