The PS Series power supplies are DC constant-voltage (CV), constant-current (CC) power supplies based on the variable switching method, featuring compact size, light weight, excellent reliability and the variable outputs. They have been designed as highly universal stand-alone type models putting emphasis on the ease of operation and safety and equipped with a variety of protection functions. Three capacity types are available including 360W, 720W, and 1080W and 13 kinds of variations are available by combining ranges of 0 to 6 V, 10 V, 20 V, 36 V and 60 V. Several versatile applications are also provided including remote control functions with GP-IB control capability (which is possible when the optional GP-600 is used.) Compact Size, Light Weight, High Efficiency Thanks to the advanced switching method, the PS Series power supplies are both compact and light , with less than half the mass and volume of previous Power Supply models, resulting in an excellent space factor and high efficiency .Digital Display of Voltage and Current Output voltage and current are indicated on 7-segment red LED displays to allow easy checking.
