Description

Pegasus P1800 Range are DC High Voltage Power Supplies 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 option of grid and filament outputs is available, please contact the factory for more information.

Capacitor Charging Option:

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

Protection

• 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.

Safety

• This power supply contains hazardous voltages and stored energy. Contact with the output may result in fatal injury. It should only be used and maintained by trained personnel.
• The area where the power supply is to be used should be kept clean and dry.
• Keep a safe distance from the output connector and any items connected to it.
• Ensure that a secure connection is made between the Earth side of the load and the green and yellow Earth lead.
