GW Instek introduces the GPE-X323 series high resolution power supply to the global market. As a front-runner in the power supply manufacturing industry, GW Instek adheres to the policy of highest production quality so as to ensure the qualitative edge over the competitors. The GPE-X323 series features output power from 192 to 217 watts, three independent isolated output channels (GPE-X323), high resolution, low noise, high reliability, key lock function, and compact size. The GPE-X323 series has firmly established another new paradigm for GW Instek in manufacturing economy linear D.C. power supplies.
