GW Instek GPR-25H30D - 750W Linear D.C. Power Supply
The GPR-U Series are single output, 500 to 900W, linear DC power supply. Overload and reverse polarity protection, in addition to the standard OVP/OCP/OTP, protects the GPR-U Series and their load from unexpected conditions. High regulation and low ripple/noise are maintained at 0.01% and < 2mVrms, respectively for CV mode. The GPR-U Series can be ordered with a customized output requirement from voltage rating from 8 to 1000V and current rating from 0.5 to 75A, (under 1kVA available). The GPR-U Series are the ideal lineup for system applications requiring large output capacity or custom-made output settings, such as material testing and product copper plating.
