Overview
The power supplies of the AG7435 family house 24 or 12 independent high voltage channels. The AG7435 is available in different versions equipped with SHV or with Radiall Multipin connector.

Radiall multipin connector
Single width (5 TE wide), 24 channel for Mod.AG7435N, AG7435P |
|
SHV connector
Single width (5 TE wide), 12 channels for Mod.AG7435DN, AG7435DP |
Consult our connectors reference page for technical information.
The board is available with either positive or negative output polarity. The channels share a Common Ground and the output voltage range is 0 ÷ 3.5 kV, with 5 mV of set and monitor resolution. The output channels offer dual current ranges (software selectable):
| High Power: | 0 ÷ 3.5 mV | I set resolution: 10 nA | I mon resolution: 10 nA |
| High Resolution: | 0 ÷ 350 μA | I set resolution: 10 nA | I mon resolution: 1 nA |
Independently programmable for each channel:
| Output voltage | 0 ÷ 3.5 kV | step: 5 mV |
| Current limit (Iset) | 0 ÷ 3.5 mA | step: 10 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 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 (only for Multipin Connector versions). |
For boards with Radiall 52 pin connector are available the following accessories:
