Overview

The CAEN Mod.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 20mV set/monitor resolution. The maximum current value is 10 mA with a 500 nA setting resolution.

Single width (5 TE wide), 8 channels for Mod. A1626

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: 500 nA I mon resolution: 50 nA Max. power: 10W
High Resolution: 0 ÷ 1 mA I set resolution: 500 nA I mon resolution: 5 nA

Independently programmable for each channel:

Output voltage 0 ÷ 1 kV step: 20 mV
Current limit 0 ÷ 10 mA step: 500 nA
HV Ramp up/down 1 ÷ 100 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
 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.
Safety Board Interlock this protection disables the HV generation when the HV outputs are not connected to their loads.
