High Voltage Power Supply


TREK Model 610E High Voltage Power Supply Amplifier Controller

The Trek Model 610E is a high voltage power supply, amplifier, and controller that is used in many applications including closed-loop charge control, electrophotographic research, insulation testing, dielectric material evaluation, and as an amplifier for AC or DC calibrators and power supplies. The Model 610E has an output voltage range of 0 V to ±10 kV with an output current range of 0 to ±2000 µ A, and can be operated in any of the six modes.

As a high-voltage amplifier, the Model 610E amplifies an externally applied signal. The gain is switch selectable between 100 V/V or 1000 V/V. As a high-voltage reference power supply, a front panel dial commands the output voltage.

As a transconductance amplifier, an externally applied voltage signal produces a proportional output current. The transconductance gain is switch selectable between 20 µ A/V or 200 µ A/V.

As a current supply, a front panel dial commands the output current. As a high-voltage controller, the high-voltage amplifier mode is maintained, but the amplifier input and feedback elements are uncommitted and available for configuration by the user.

As a transconductance controller, the transconductance amplifier mode is maintained, but the amplifier input and feedback elements are uncommitted and available for configuration by the user.

The Model 610E features a compliance limit function. When in a CURRENT command mode, the compliance function is voltage. When in a VOLTAGE command mode, the compliance function is current. The current compliance limit function can be based upon either the total current or a specific load current path.

The Model 610E features a four-quadrant, active output stage that sinks or sources current into reactive or resistive loads throughout the output voltage range. This is essential for achieving the accurate output response and high slew rates demanded by reactive loads. The Model 610E is protected against overvoltage and overcurrent conditions that may be generated by active loads or by output short circuits to ground.

Precision voltage and current monitors provide low-voltage representations of the high-voltage output and load current for monitoring purposes, or for use as feedback signals in a closed-loop system. The current control loop provide a means for close regulation of either the total load current, I(t), or a specific current path, I(r). When the load includes several current paths, one may be chosen, I(r), to be closely regulated.
