PGU-HP is the basis of our laboratory devices and can be purchased in various designs with different voltage and current ranges, depending on requirements. Current ranges from 1A to 200A and voltage ranges from 10V to 400V are covered. The smallest measuring range can be 100nA. All devices are available with and without an impedance module.
PGU-HP is controlled using the EcmWin software.
