PLR-Series Low Noise D.C. Power Supply

GW Instek launches the new generation PLR series programmable switching D.C. power supply. The single power output ranges are 360W and 720W. The series comprises 6 models and the voltage ranges are 20V, 36V and 60V.  The PLR series is a hybrid circuit design which incorporates front stage switching and rear stage linear architectures. The unique advantages of this design benefit from the combination of both switching and linear structures. The front stage switching structure can effectively reduce size and weight, and the rear stage linear structure can maintain lower ripple voltage, lower ripple current, and faster transient response.  

There are 6 models of the PLR series. Model number, output voltage, output current and output power are as follows:

Model number PLR 20-18 PLR 20-36 PLR 36-10 PLR 36-20 PLR 60-6 PLR 60-12
Output channel 1 1 1 1 1 1
Output voltage 0~20V 0~20V 0~36V 0~36V 0~60V 60V
Output current 0~18A 0~36A 0~10A 0~20A 0~6A 12A
