Overview
A1626 is a single width board (5TE wide) that houses 16 individual floating channels, delivered through DB37 connector. The output voltage is 0 ÷ 1000 V with 50mV set/monitor resolution. The maximum current value is 10mA with a 1 µA setting resolution.

Consult our connectors reference page for technical information.
The channels share a Individual Floating Channels, which allows on-detector grounding, reducing the noise level. A global enable/disable connector allows to disable the channels. The voltage ramp rates may be set independently for each channel and offer dual current ranges (software selectable).
The output channels offer dual current ranges (software selectable).
| High Power | 0 ÷ 10 mA | I set resolution: | 1 µA | I mon resolution: | 1 µA | Max. power: | 10W |
| High Resolution: | 0 ÷ 1 µA | I set resolution: | 1 µA | I mon resolution: | 100 nA |
Independently programmable for each channel:
| Output voltage: | 0 ÷ 1 kV | step: 50 mV |
| Current limit: | 0 ÷ 10 mA | step: 1 µA |
| HV Ramp up/down: | 1 ÷ 250 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 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.
