Overview

The CAEN Mod. SY8800 is a high density floating low voltage power supply system, designed to power low noise electronics with medium and high currents. Six modules have been developed so far:

  • 2÷7V 550W (typ. 110A @5V)
  • 2÷7V 1100W (typ. 220A @5V)
  • ±7÷16V 550W (typ. 23A @±12V)
  • ±7÷16V 1100W (typ. 46A @±12V)
  • ±20÷28V 550W (typ. 11A @± 24V)
  • ±20÷28V 1100W (typ. 22A @± 24V)

The system is factory-configured. The system is provided with Remote Sensing Lines to compensate for the voltage drop over the connection cables.

Module control can take place either locally, assisted by a Graphic colour display or remotely, via Ethernet, USB, CANBUS and RS232.

Safety features allows the module to perform as a current generator and includes:

Channels can be enabled or disabled through the Interlock logic. The LV output Ramp-up and Ramp-down times may be selected independently for each channel in 5ms steps.
Overvoltage and Undervoltage protection 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.
Programmable maximum channel output voltage limit (VOVP): the channel is tripped off when its output voltage exceeds VOVP.
Safety Board Interlock this protection disables the HV generation when the HV outputs are not connected to their loads.
