High-voltage Power Amplifier

  • Product No:609E-6
  • Manufacturer:Trek, Inc.

The Model 609E-6 is a DC-stable, high-voltage power amplifier used in industrial and research applications. It features an allsolid-state design for high slew rate, wide bandwidth and lownoise operation.  The four-quadrant, active output stage sinks or sources current into reactive or resistive loads throughout the output voltage range.  This type of output is essential to achieve an accurate output response and high slew rate demanded by a variety of loads such as highly capacitive or reactive loads. It is configured as a non-inverting amplifier, an inverting amplifier or as a differential amplifier. Different input configurations can be wired into the unit.

Features

High Voltage On/Off   

Local: Individual push-button switches  

Remote: TTL high turns OFF the high voltage; TTL low turns on the high voltage 

Dynamics Adjustments: Graduated 1-turn potentiometer used to optimize the AC response for various load parameters 

Current Limit/Trip: Switch selectable for limit or trip. Graduated 1turn potentiometer adjusts from 0 to 20 mA 

Out of Regulation: LED illuminates and BNC provides a TTL low when Model 609E-6 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
