Description

The Pegasus P600 and P900 Range are DC High Voltage Power Supplies suitable for laboratory and industrial use. The option of grid and filament outputs make this range of supplies suitable for electron beam systems and x-ray applications. 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 Pegasus range can be adapted to suit capacitor charging applications at low to moderate PRF.

Protection

Safety interlocks:

There is a safety interlock to enable or disable high voltage output. It is available on the external control interface.

Circuit protection:

In overload, arcing or short-circuit situation, the power supply trips.
Controls

Controls

Control interface:

The Pegasus P600/900 power supplies can be controlled by connecting external control interface to SK1. Genvolt can also supply the specially designed control panel. This is available as having full digital metering facilities and includes a remote interface. Please see more information in the data sheet.
