This new pair of CAEN general purpose power supplies will provide you with tremendous power and resolution performance at a cost effective price! You will never have to compromise again. The x7235 and x7236 house 12, 24 or 32 independent high voltage channels, available with either positive or negative polarity, compatible with CAEN Universal Multichannel Power Supply Systems (SY1527, SY2527, SY3527, SY4527, SY5527).

CAEN provides 2 different channel grounding: Common Ground (AG7236/AG7435) for standard applications, and Common Floating Return (A7236/A7435 - on-detector grounding) suitable for applications with more stringent noise requirements.The floating return is insulated from the crate earth up to ±25 V.

The boards are available in different versions equipped with SHV or Radiall Multipin connectors.

The output voltage range is 0 ÷ 3.5 kV, with 5 mV of set and monitor resolution.

The output channels offer dual current ranges (software selectable).

A7236/AG7236 Dual range current:

A7435/AG7435 Dual range current:

Independently programmable for each channel:

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 and IMAX:maximum output voltage and maximum current value can be fixed, via front panel potentiometer, at the same common value for all the board channels. IMAX and VMAX values can be read out via software.
Safety Board Interlock: this protection disables the HV generation when the HV outputs are not connected to their loads. <sup>(1)

Modularity, Compatibility, Connectivity, Usability and Solidity are the keywords of the system design. The Mainframes have been specifically designed to power all detector technologies found in modern Physics Experiments, such as photomultipliers, wire chambers, streamers tubes, silicon detectors and others.

The systems are modular, flexible and match not only the requirements of major experiments with large number of channels but also the practical needs of test laboratories, where simple manual operations on a limited number of channels are often desired.
