A1561H is a double width board (5 TE wide) that houses 12 Independent high voltage channels. The board is available with positive, negative or mixed polarity. Channels are delivered through SHV connectors.
– Single width (5 TE wide), 12 channels (Mod. AG561HD)
– Double width (10 TE wide), 24 channels (Mod. AG561HS)
The output voltage range is 0 ÷ 6 kV with 10 mV monitor resolution. The Maximum output current is 20 μA with 50 pA monitor resolution.
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).
Independently programmable for each channel:
|Output voltage:||0 ÷ 6 kV||step: 100 mV|
|Current limit (Iset):||0 ÷ 20 μA||step: 500 pA|
|HV Ramp up/down:||1 ÷ 500 V/sec||step: 1 V/sec|
Safety features 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 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: 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.
