Trek high-voltage amplifier/supply model PD07083
TREK Model PD07083 Power Amplifier/Supply
This is a factory engineered and modified model, similar to Trek model 677B but extending accuracy and range. This model's factory specifications as built are detailed below and are listed in this model's specific original owner's manual provided.
The Trek Model PD07083 is a high-voltage power amplifier/supply unit for precise control of output voltages in the range of 0 to 2 kV DC or peak AC with an output current range of 0 to 5 mA DC or peak AC. The Model PD07083 can be operated in one of two modes: as a high-voltage amplifier where it is configured as a noninverting amplifier with a fixed gain of 500 V/V, or as a high-voltage power supply which responds to front panel controls to command an exact output voltage or current.
The Model PD07083 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 PD07083 is protected against over-voltage and over-current conditions that may be generated by active loads or by output short circuits to ground.
The Digital Enable feature provides a connection for a remote device to turn on and off the high-voltage output. This makes the Model PD07083 suitable for automated or computer-controlled systems.
The Model PD07083 can be operated on a bench top or, with optional hardware, in a standard 19-inch rack.
