Overview

The CAEN Mod A2550  is a single width board (5 TE wide) that houses 8 independent Low Voltage Individual Full Floating channels, compatible with the CAEN Universal Multichannel Power Supply System (SY4527, SY5527).

Channels are delivered with D-Sub 8W8 connectors. Consult our connectors reference page for technical information.

A2550 Individual Full Floating channels allow on-detector grounding, reducing the noise level. The floating channels are insulated from each other up to ±500 V. Each output channel is provided with individual remote sensing lines to compensate for the voltage drop over the connection cables.

The output voltage range is 0 ÷ 5 V, with 0.1 mV monitor resolution. The maximum output current is 16 A, with 5 nA monitor resolution. The Maximum channel power is 60 W.

Independently programmable for each channel:

 

Output voltage:

 

0 ÷ 5 V

 

Step: 0.1 V

 

Current limit (Iset):

 

0 ÷ 16 A

 

Step: 0.5 mA

 

V Ramp up/down:

 

1 ÷ 500V/s

 

Step: 1 V/sec

 

TRIP parameter

 

0 ÷ 999.9 s; 1000 s = Infinite

 

Step: 0.1 s

Safety features include:

  • Overvoltage detection: if a channel voltage exceeds the programmed Overvoltage threshold value (OVVThr), it is signaled to be in “overvoltage” and is switched off.

  • Undervoltage detection: if a channel voltage decreases below the programmed undervoltage threshold (UNVThr), it is signaled to be in “undervoltage” and is switched off.

  • Overcurrent detection: if a channel tries to draw a current larger than its programmed limit, it is signaled to be in “overcurrent”; when overcurrent is detected, the relevant channel can be programmed either to turn off after a programmable trip time or to keep providing the maximum allowed current: this feature allows the module to work as current generator.

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 CAEN Control Software 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.
