TREK Product - 2205 40W High Voltage Amplifier

TREK Model 2205 High voltage amplifier

Trek Model 2205 is a member of Trek’s 2200 Series of high-voltage 40 watt amplifiers offering high performance at an attractive price. Model 2205 provides precise control of output voltages in the range of 0 to +/-500 V DC or peak AC with an output current range of 0 to +/-80 mA peak AC and large signal bandwidth DC to 75 KHz (-3dB).

The Model 2205 incorporates high performance features including DC stability, wide bandwidth, well regulated and controlled AC output signals, full four-quadrant class AB all-solid-state output stages, DC offset adjustment with front panel metering, and auto-recovery shutdown to protect the output from being overpowered.

The 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.

Model 2205 comes with a 2-year warranty, is CE marked, RoHS compliant and HALT tested.

Applications for Model 2205 include piezoelectric, electro-optic, MEMS and many other areas of research.

PRODUCT FEATURES

Digital Enable
A BNC connection for TTL compatible signal to turn on and off
the high-voltage output is provided for each channel. A TTL high
(or open) turns off the high-voltage output. A TTL low turns on the
high-voltage output.
Response
A graduated potentiometer is used to optimize the AC response
of the output signal under various load parameters.
High-Voltage LED
Front panel red LED illuminates when the high-voltage is on.
Voltage Monitor
A buffered output provides a low-voltage replica of the high-voltage output.
Scale Factor
1/50th of high-voltage output
Current Monitor
A buffered output provides a low-voltage representation of the load current.
Scale Factor
0.1 V/mA
