Module control via software Tools
The CAEN Mod. V6533 is a 1-unit wide VME 6U module housing 6 High Voltage Power Supply Channels 4 kV, 3 mA (9W max). The board is available with either positive or negative output polarity; mixed version with 3 positive and 3 negative channels is also available. The channels share a common floating return, which allows on-detector grounding reducing the noise level. HV outputs are delivered through SHV connectors.

SHV connector Single width (1-unit wide), 6 channels for Mod. V6533 |
Consult our connectors reference page for technical information.
The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1÷ 500 V/s range with 1 V/s steps.
The module features 50 nA Iset/Imon resolution. Features include Imon Zoom, increasing resolution to, increasing resolution to 5 nA. The modules fit into both VME/VME64 standard and V430 crates. Functional parameters can be programmed and monitored via VMEbus.
A complete set of free software Tools is available to control this unit: GECO2020 with user friendly GUI and CAEN HV Wrapper library for custom SW development. OPC Server also supported.
Safety features allows the module to perform as a current generator and includes:
|
Channels |
can be enabled or disabled through the Global Interlock logic. Channels individually enabled via front panel jumpers (passive or active mode available). |
|
Overvoltage and Undervoltage |
warning when the output voltage differs from the programmed value. |
|
Overcurrent detection |
if a channel tries to draw a current larger than its programmed limit, it enters TRIP status, keeping the maximum allowed value for a programmable time (TRIP), before being switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator. |
|
Hardware VMAX and IMAX |
Maximum output voltage and maximum current value can be fixed, via front panel potentiometer, at the same common value for all the board channels. IMAX and VMAX values can be read out via software. |
Available Options:
-
A6580 DC Input Power Equalizer.
-
10 Imon Zoom, increasing Imon resolution to 500 pA.
These modules are provided with a USB VCP interface and can be programmed via PC by connecting the PC USB port with the N14xx USB B-type port; the featured controller (FT232BM chip) requires a driver available on this page or at www.ftdichip.com

Trip |
Max. time an “overcurrent” is allowed to last (seconds). A channel in “overcurrent” works as a current generator; output voltage varies in order to keep the output current lower than the programmed value. “Overcurrent” lasting more than set value (1 to 9999) causes the channel to “trip”. Output voltage will drop to zero either at the Ramp-down rate or at the fastest available rate, depending on Power Down setting; in both cases the channel is put in the OFF state. If trip= INFINITE, “overcurrent” lasts indefinitely. |
