  • 12 / 24 / 32 independently controllable High Voltage channels

  • Output Voltage: 500 V

  • Dual range current:

    • High Power: 1 mA (1 nA monitor resolution)

    • High resolution: 0.1 mA (0.1 nA monitor resolution)

  • Available with Negative / Positive / Mixed Polarity

  • SHV / DB25 connectors

  • Floating Type: Common Floating Return

  • Low ripple

  • Under/over-voltage alert, overcurrent and max. voltage protection

  • Interlock logic for unit enable

  • Software Tool for easy channel management

The power supplies of the A1542H Family house 12 / 24 / 32 independent high voltage channels.

The channels share a Common Floating Return, which is insulated from the chassis/crate ground. This feature may help to minimize problems of ground-loops. The board is available with positive, negative or mixed output polarity. Channels are delivered with SHV / DB25 connectors. Consult our connectors reference page for technical information.

The output voltage range is 0 ÷ 500 V, with 1 mV monitor resolution. The output channels offer dual current ranges (software selectable):

High Power:

0 ÷ 1 mA

I set resolution: 20 nA

I mon resolution: 1 nA

High Resolution:

0 ÷ 0.1 mA

I set resolution: 20 nA

I mon resolution: 0.1 nA

Independently programmable for each channel:

Output voltage:

0 ÷ 500 V

Step: 10 V

Current limit (Iset):

0 ÷ 1 / 0.1 mA selectable

Step: 20 nA

V Ramp up/down:

1 ÷ 100 V/s

Step: 1 V/sec

TRIP parameter

0 ÷ 999.9 s; 1000 s = Infinite

Step: 0.1 s

Safety features 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 allows to disable the primary HV generation when the HV outputs are not connected to their loads.

CAEN provides a complete software range to control, monitor and configure its Power Supply products.

  • GECO2020 GEneral COntrol Software

  • CAEN HV Wrapper Library,

  • HiVoCS web tool

  • OPC Server for CAEN Power Supplies

  • EPICS Service

These tools, which support the most used operating systems, spread from low level libraries (CAEN HV Wrapper Library), to be used as a source for customer designed software, to the WEB interface (HIVOCS) available on each mainframe, up to the all-inclusive Control Software (GECO2020) with user friendly graphical interfaces, to meet any application need.

Advanced control via OPC Server (CAEN OPC Server) and EPICS (EPICS IOC) is supported, to easily include CAEN power supplies within existing setups featuring such standards. All CAEN Control Software are available for free download.
