Model 601C DC-Stable High-Voltage Power Amplifier

Now equipped with SHV type high-voltage output connectors.

The Trek Model 601C is a DC-stable, high-voltage power amplifier designed to provide precise control of output voltages in the ranges of:

0 to ±500 V, DC or peak AC, 0 to -1 kV, DC or peak AC,
0 to +1kV, DC or peak AC.

With an output current in the range of: 0 to ±10 mA DC, 0 to ±20 mA peak AC.

The Model 601C features an all solid-state design for high slew rate, wide bandwidth, and low-noise operation. The four-quadrant, active output stage 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 601C 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 Digital Enable feature provides a connection for a remote device to turn ON and OFF the high voltage of the instrument. This makes the Model 601C ideal for automated or computer controlled systems. The Model 601C has a Dynamic Adjustment feature which can be used to optimize the AC response of the output signal.

The Model 601C is available in single channel or dual channels configurations. These units can be operated on a bench top or, with optional hardware, in a standard 19-inch rack.

The Model 601C can be operated as a noninverting or inverting amplifier with a fixed gain of 100 V/V. The input gain of the 601C can be programmed for 50 V/V for the ±500 V range only. The Model 601C comes from the factory with settings for an output voltage of ±500 V DC or peak AC, an input signal ratio of 100:1 V/V, and a noninverting input.
