1. Overview
The Mod. A1536 – AG536 is a family of HV boards, available with either positive or negative polarity, compatible
with the CAEN Universal Multichannel Power Supply System (SY1527, SY2527, SY3527, SY4527, SY5527).
The A1536 and A1536H channels share a common floating return, which allows on-detector grounding reducing the
noise level; the floating return is insulated from the crate earth up to ±50 V (with a 65 V hardware limit); the return
of the AG536 channels is wired to the crate Earth reference.
A1536 and AG536 output range is 0 ÷ 3 kV, with 1 mA maximum output current (800µA for A1536V and AG536V)
and 100mV set and monitor resolution. A1536H output channels offer dual current ranges (software selectable):
High Power: 0 ÷ 1 mA (Iset res.: 20 nA; Imon res.: 1 nA; 1.5W maximum channel power) and High Resolution:
0 ÷ 100 µA (Iset res.: 20nA; Imon res.: 100 pA); it features also 50mV and 5mV set and monitor resolution
respectively.
The boards are provided with both current and voltage protections. If overcurrent occurs, the relevant channel can
be programmed either to turn off after a programmable trip time or to keep on providing the maximum allowed
current: this particular feature allows the modules to work as current generator. The maximum output voltage can
be fixed, through a potentiometer located on the front panel, at the same common value for all the board channels
and this value can be read out via software.
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).
The 12 channel versions output voltages are provided via SHV connectors; 24 channel versions are available with
either SHV connectors or Radiall 52-pin connector; all other models feature a Radiall 52-pin connector. 24 channel
SHV versions are double width boards (10 TE); all other versions are single width (5 TE). "Multipin" versions have
also the safety board interlock: this protection allows to disable the primary HV generation when the HV outputs
are not connected to their loads.
