A7526D

The CAEN Mod.A7526DB Power Supply Module is a compact desktop solution to provide stable and noiseless power supply for several kinds of detectors.

The module houses a digital controlled high voltage channel that provides a 2.6 kV maximum voltage with 100 mV monitor resolution The maximum output current is 500 μA, with 10 nA monitor resolution. It is available with either positive or negative output voltage. HV output is delivered through SHV connector.

The following channel parameters can be programmed:

• Output voltage: 0 ÷ 2.6 kV step: 100 mV

• Current limit 0 ÷ 500 μA step: 100 nA

• Voltage Ramp up/down: 1 ÷ 500 V/sec step: 1 V/sec

• TRIP parameter

Power supply control can be performed remotely, via RS485, that allows to build a daisy chain network of A75xxDB modules.

Safety features include:

• Overcurrent detection: if the channel attempts to draw a current larger than Iset, the output voltage is automatically adjusted to keep the current below Iset limit. Under this condition, the channel behaves as a current generator.

• The Module can be enabled or disabled through the interlock logic.
