Overview
The 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 provided with Remote Sensing Lines to compensate for the voltage drop over the connection cables. Safety features include:
- Overvoltage and Undervoltage protection when the output voltage differs from the programmed value
- Programmable maximum channel output voltage limit (VOVP): the channel is tripped off when its
output voltage exceeds VOVP - 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.
- 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.
Module control can take place either locally, assisted by a Graphic colour display or remotely, via Ethernet, USB, CANBUS and RS232.
