Overview

The CAEN Mod A1625B  is a single width board (5 TE wide) that houses 8 independent high voltage channels.

All channels have independent floating returns, isolated up to 50 V from each other and from chassis/crate ground (Individual Floating channel) The board is available with positive, negative or mixed output polarity. Channels are delivered with DB37 connectors. Consult our connectors reference page for technical information.

The output voltage range is 0 ÷ 1000 V, with 20 mV monitor resolution. The output channels offer dual current ranges (software selectable):

 

High Power: 0 ÷ 25 mA

 

High Resolution: 0 ÷ 2.5 mA

 

I set resolution: 500 nA

 

I set resolution: 500 nA

 

I mon resolution: 100 nA

 

I mon resolution: 10 nA

 

Independently programmable for each channel:

 

Output voltage:

 

0 ÷ 1000 V

 

Step: 20 mV

 

Current limit (Iset):

 

0 ÷ 25 / 2.5 mA selectable

 

Step: 500 nA

 

V Ramp up/down:

 

1 ÷ 100 V/s

 

Step: 1 V/s

 

TRIP parameter:

 

0 ÷ 999.9 s; 1000 s = Infinite

 

Step: 0.1 s

 

Safety features include:

  • 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:

  • 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, ranging  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 needs.

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 tools are available for free download.

 

Universal Multichannel Power Supply Systems (Mainframes)

Universal Multichannel Power Supply Systems, or Mainframes, are modular systems designed to house and control High Voltage (HV) and Low Voltage (LV) boards, providing power for particle detectors and their associated electronics in standard 19” racks. CAEN offers four mainframe versions:

  • SY4527: A large experimental system. This 19” wide / 8U high mainframe can house up to 16 HV/LV boards. It offers a power output from 600W up to a maximum of 4200W, depending on installed Power Supply Units and display type. Local control is optionally available via a 10.4” or 5.7” LCD Touchscreen.

  • SY5527: A more compact laboratory version. This 19” wide / 4U high mainframe can house up to 6 HV/LV boards. Its power output ranges from 600W up to a maximum of 1800W, depending on Power Supply Units. Optional local control is available via a 5.7” LCD Touchscreen.

  • SY4527LC: A cost-effective alternative with a shorter depth (~20cm compared to standard SYx527). This 19” wide / 8U high mainframe houses up to 10 boards and includes a 600W power supply. It does not include an LCD display. It is fully compatible with SY4527 and SY5527 boards.

  • SY5527LC: Also a cost-effective, shorter depth alternative (~20cm compared to standard SYx527). This 19” wide / 4U high mainframe houses up to 4 boards and includes a 400W power supply. It does not include an LCD display. It is fully compatible with SY4527 and SY5527 boards.

All systems offer modular design for simplified upgrades and maintenance and can be controlled remotely via Ethernet.
