AG590 is a double width module (10 TE wide) that houses 16 Independent high voltage channel is delivered through Radiall 52 pin HV connectors. The board is available with either positive or negative output polarity. The channels share a Common Ground. The output voltage can be programmed and monitored in the 0 ÷ 9 kV range with 10 mV monitor resolution. The Maximum current full scale is 50 μA with 100 pA Iset/Imon monitor resolution.

Single width (5 TE wide), 16 channels for Mod. AG590

Consult our connectors reference page for technical information.

Independently programmable for each channel:

Output voltage 0 ÷ 9 kV step: 200 mV
Current limit 0 ÷ 50 μA step: 1 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 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.

Accessories available:

  • Mate cable connector (Mod. A996) and relevant insertion/extraction tool (Mod. A995)
