Power Supply 19"-PSU350-2DSW
Double Digitally Controlled Precision Linear Power Supply 2× ±350 V / 0.5 A

Jump to: Technical Data Additional Information

This linear power supply unit can be used to supply our power switches. It contains two independent power supply units that can provide symmetric output voltages. The reference potential (i.e. the output ground at the SHV socket) determining the potential of the trap center must be supplied by an external voltage source. The output current of the power supply unit is electronically limited and its magnitude depends on the output voltage and the heatsink temperature. At the maximum output voltage of ±350 V, an output current of 500 mA minimum can be reached.

The power supply can be remote-controlled by an RS232 interface. The output voltages and current limits can be controlled with a 16-bit precision. Using the RS232 interface, the device state can be monitored and the output voltages and currents can be measured. The device settings are stored in a nonvolatile memory and are restored when the device is powered on again. The device output can be disabled by a digital enable signal connected to the BNC socket on the front panel.
