Pegasus P1800 Rack Power Supply1800W 19 inch rack 3U

If you would like to learn more about this product: Please Contact Us

The Pegasus P1800 Range rack power supply is a general purpose DC High Voltage Power Supply suitable for laboratory and industrial use. Standard remote control is by analogue signals. Should other controls be preferred please discuss this with our technical staff. Available in a standard 19-inch rack. Reduced weight and ease of serviceability is ensured, as the supplies are air insulated below 20kV.

The rack power supply can be provided with either a negative or positive polarity with an option of grid and filament outputs being available, please contact us for more information when requesting a quote or placing an order.

Capacitor Charging Option:

The Pegasus range can be adapted to suit capacitor charging applications at low to moderate PRF.

  • A trip occurs after excessive sparking or the occurrence of an error. The counter in the circuit limits the spark rate.
  • Current limit provides overload and short circuit protection.
  • Primary over-current protection is provided by the inverter circuits.

Control Interface

The Pegasus P1800 power supplies can be controlled by connecting an external control interface to the Harting connector or the D-Sub connector. Genvolt can also supply specially-designed control panels for customer requirements. Please see more information in the data sheet.
