Trek High Voltage Power Supply and Amplifiers

Contact us by email for more information: admin@polyktech.com

        Trek high voltage power supplies and amplifiers are widely used in studying piezoelectric and ferroelectric materials for actuators, charge - discharge capacitors, performing polarization loop test, electrostatic, corona, speakers, etc. They have very stable DC output, broad bandwidth, fast response (high slew rate), serve as both power source and power sink, and very high reliability. In our lab, we have multiple Trek amplifiers made in 1990's and they are still working very well without any issue. Our engineers have compared the performance of several high voltage amplifiers, and Trek outperforms many of the other models.

Trek 20/20A-G High Voltage Amplifier, +/-20 kV, 20 mA, Refurbished Warranty

Trek 20/20A-G high voltage amplifier fully cleaned and inspected. Although there are some scratches in the front panel, but it is fully functional.

This is an older model. current model with similar function is 20/20C, whose performance you can find in the manufacturer's website.

DC - stable output voltage

Current limit function.

Output voltage: +/-20 kV

Current: +/-20 mA

Fixed Votlage Gain: 2000 V/1 V.

Please check the pictures carefully, we do not have the output high voltage cable, so we use silicone to attach a 40kV/18AWG/150C high voltage cable (>6ft long) to the output and we verified that the output voltage is correct.

As a power supply and power sink.

Fully functional and performed informal calibration by measuring the output voltage.

Note: this unit has line voltage of 115 V
