Trek P0621 High-Voltage Power Amplifier - Manual (Page 2)

Features
High Voltage On/Off
Local Individual push-button switches
Remote TTL high turns OFF the high voltage; TTL low
turns on the high voltage
Dynamics
Adjustments Graduated 1-turn potentiometer used to
optimize the AC response for various load
parameters
Current Limit/Trip Switch selectable for limit or trip. Graduated 1-
turn potentiometer adjusts from 0 to 20 mA
Out of Regulation LED illuminates and BNC provides a TTL low
when P0621 fails to produce HV output such as
during a current limit
Trip Status LED illuminates and BNC provides a TTL low
when HV is disabled due to the output current
exceeding the current trip level, a high voltage
fault is detected or the top cover is removed
Fault Status BNC provides a TTL low when P0621 is out of
regulation for greater than 500 ms
