Overview
The CAEN Mod. A7460 is a 12 channel HV board, available with either positive or negative polarity, compatible with the CAEN Universal Multichannel Power Supply System (SY1527, SY2527, SY4527, SY5527). The A7460 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.

Consult our connectors reference page for technical information.
The output voltage range is 0 ÷ 6 kV, with 10 mV of set and monitor resolution. The output channels offer dual current ranges (software selectable):
| High Power | 0 ÷ 1 mA (6 W Max) | I set resolution: 5 nA | I mon resolution: 2 nA |
| High Resolution | 0 ÷ 100 μA | I set resolution: 5 nA | I mon resolution: 200 pA |
Independently programmable for each channel:
| Output voltage | 0 ÷ 6 kV | step: 10 mV |
| Current limit (Iset) | 0 ÷ 1 mA | step: 5 nA |
| V Ramp up/down | 1 ÷ 500 V/sec | step: 1 V/sec |
| TRIP parameter | 0 ÷ 999.9 s; 1000 s = Infinite | step: 0.1 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 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 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. |
