AC HV power supply, ±8 kV @ 1mA RMS

CPS Model 7201 is a dual output, constant current ,+/- 8 kV AC power supply.

AC Waveform

Designed specifically for corona generation used for dissipation of static charge, the 7201 provides a square waveform of balanced positive and negative current. Maximum RMS current is 1mA at a voltage of up to 8 kV per polarity, or 16 kV peak-to-peak. Default frequency is 400Hz, configurable from 5HZ to 2000Hz.

Below is the 7201 waveform with an output connected to a resistive load. Shown at maximum power, configured at 400Hz:

Outputs

2 synchchronized HV outputs are available. Output 1 is permitted to float to the DC bias of the corona discharge device. Output 2 forces balanced positive and negative voltages with respect to ground. In addition, a clock signal is provided on the connector to allow two 7201 units to be synchronized with a 180 degree phase shift.

Control

Both outputs are current-controlled independently with separate analog program signals . A program voltage of 2.5 VDC to 5.0 VDC provides linear proportional adjustment of the output current from 500uA up to 1mA RMS

Metering

The 7201 provides Voltage monitor signals for each output. A monitor value of up to 8VDC is directly proportional to the average absolute peak voltage.
