Model BP-18

Power Supply for Beam Penetration CRTs

 


Basic Description

The Genvolt BPU is a product designed to offer alternatives to obsolete fast-switching high voltage power supplies such as those manufactured by other suppliers.

The power supply has two TTL-compatible input lines which select one of four preset voltage levels. The preset potentiometers are accessible through holes in the front of the unit.

Specification 
Input voltageVDC nominal. +/-2V range
Input currentVaries with load frequency. 60Hz, 600pF requires <1.5A
Output voltage8kV to 18kV
Output rippleTypically <0.1%
Load/Line regulationTypically <0.1%
Output DC current500μA continuous but with switching pulse currents of the order of 100mA.
Capacitive loadSpecified with 600pF load. Will work with higher or lower amounts of capacitance, though rise and fall times may change.
Rise and fall times150μsec settling time to <0.5% for 10kV voltage change.
Switching frequency60Hz continuous. May operate in bursts up to 300Hz typically. User to control average switching rate within acceptable limits. Please consult factory.
Dimensions80mm high, 152mm wide and 215mm deep, excluding connectors
Connectors 
DC and control
15-way ‘D’
HV output
Proprietary connector based on Type ‘N’. Mating cable and connector supplied with PSU.
Environmental Must be mounted onto ‘cold plate’ at or below 40C. Will operate without cold plate at reduced duty/frequency. -20C to +40C operational limits – consult factory.
