Trek 20/20C


Non-Inverting High Voltage Amplifier, Output Voltage 0 to ±20 kV DC or Peak AC

Meet the demands of highly capacitive or reactive loads. The DC-stable Trek® 20/20C high-voltage power amplifier has a four-quadrant, active output stage that is essential to achieve accurate output responses and high slew rates. It sinks or sources the current into reactive or resistive loads throughout the output voltage range. The Trek 20/20C is used in numerous industrial and research applications such as material characterization, ferroelectrics, and atmospheric plasma. Advanced Energy’s Trek 20/20C-HS high voltage amplifier offers three times more peak current, a higher slew rate, and even more bandwidth. Learn more.
