Overview

The CAEN Mod.AG538D is a single width (5TE wide) board housing 12 independent high voltage and high-power channels. The board is available with either positive or negative output polarity and equipped with SHV connector.

Single width (5 TE wide), 12 channel for Mod. AG538D

Consult our connectors reference page for technical information.

The channels share a Common Ground and the output voltage range is 0 ÷ 1.5 kV, with 10 mA maximum output current (12W channel max output power) and 50 mV set and monitor resolution. The board is available with either positive or negative output polarity and equipped with SHV coaxial connector. The HV RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1 ÷ 500 V/s range (1 V/s step).

Independently programmable for each channel:

Output voltage 0 ÷ 1.5 kV step: 50 mV
Current limit (Iset) 0 ÷ 10 mA step: 200 nA
V Ramp up/down: 1 ÷ 500 V/sec step: 1 V/sec
TRIP parameter TRIP range: 0 ÷ 999 s; 1000 s = Infinite, current
generator mode.
step = 1 s

Safety features allows the module to perform as a current generator and includes:

Channels
can be enabled or disabled through the Global Interlock logic.
Overvoltage and Undervoltage warning when the output voltage differs from the programmed value.
Overcurrent detection when a channel attempts to exceed the programmed current limit, it signaled to be in “overcurrent” and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator.
Hardware VMAX maximum output voltage can be set, via front panel potentiometer, at the same common value for all the board channels. VMAX value can be read out via software.
