Trek 30-20A High-Voltage Power Amplifier - Manual (Page 2)

Features (cont.)
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.
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 ±20 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 exceeding
the current trip level, the detection of a high-
voltage supply fault, the removal of one of the
panels, or if the Model 30/20A is out of
regulation for greater than 500 ms.
