PRODUCT FEATURES

Digital Enable A BNC connection for TTL compatible signal to turn on and off the high-voltage output is provided for each channel. A TTL high (or open) turns off the high-voltage output. A TTL low turns on the high-voltage output.

Response A graduated potentiometer is used to optimize the AC response of the output signal under various load parameters.

High-Voltage LED Front panel red LED illuminates when the high-voltage is on.

Voltage Monitor
A buffered output provides a low-voltage replica of the high-voltage output. Scale Factor 1/200th of high-voltage output

Current Monitor A buffered output provides a low-voltage representation of the load current. Scale Factor 0.4 V/mA
