Features
High-Voltage On/Off
Local Individual push-button switches
Remote TTL compatible input. TTL high (or open) turns
off high-voltage output. TTL low turns on high-
voltage output.
Dynamic Adjustment Graduated 1-turn potentiometer is used to
optimize the AC response for various load
parameters.
Current Limit/Trip Switch selectable for limit or trip. Graduated 1-
turn panel potentiometer is used to adjust limit
or trip level from 0 to ±12 mA.
Out of Regulation
Status Indicator and
Connnector Illuminates and TTL low is provided when unit
fails to produce required HV output such as
during current limit.
Limit/Trip Status
Indicator and
Connector An indicator will illuminate and a BNC will
provide a TTL low when the high-voltage output
is disabled due to the output current trip level,
the detection of a high-voltage power supply
fault, removal of one of the panels, or if the
Model 50/12 is in an out of regulation status for
greater than 500 ms.
