The GW Instek GPR-11H30D is a single output, 330W, linear DC power supply. To protect loads, the GPR11H30D features robust protection measures with overload and reverse polarity protection. Continuous or dynamic output is supported for pulsed current applications such as power amplifier testing. The high regulation and low ripple/noise makes the GPR-11H30D suitable for high-end bench-top applications requiring precision.
