Trek P0621 User Manual

Trek Model P0621P / P0621N

High-Voltage/Power DC Amplifiers

Trek Model P0621P (+) / P0621N (-) is a high-voltage DC-stable piezo driver/amplifier designed to provide precise control of output voltages in ranges that are customer specified within a range of available settings. It is configured as a noninverting amplifier with a variable DC gain. An inverting amplifier configuration is also available.

The unit features an all-solid-state design, a high slew rate and a four-quadrant active output stage which sinks or sources current into reactive or resistive loads throughout the output voltage range. This capability is essential for achieving the accurate output responses and high slew rates demanded by reactive loads.

Out of Regulation

LED illuminates and BNC provides a TTL low when P0621 fails to produce HV output such as during a current limit

Trip Status

LED illuminates and BNC provides a TTL low when HV is disabled due to the output current exceeding the current trip level, a high voltage fault is detected or the top cover is removed

Fault Status

BNC provides a TTL low when P0621 is out of regulation for greater than 500 ms
