Overview
The CAEN Mod.A1589 board contains 8 independent channels providing high-voltage through SHV connectors; it is compatible with the CAEN Universal Multichannel Power Supply System (SY1527, SY2527, SY4527, SY5527).

Consult our connectors reference page for technical information.
All channels are differential and can operate in the so called four-quadrant regimes supplying or operating as resistive load. It can provide, with an excellent long term output stability. It ensures a voltage stability within 10 mVpp, with 100 mV setting resolution. Moreover, the 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 65V hardware limit). The board is provided with both current and voltage protections. 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).
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. For each channel, it is also possible to set an output current limit in the 0 ÷ 15 mA range, in 250 nA steps. |
| Overcurrent detection | when a channel attempts to exceed the programmed current limit, it signalled 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. |
