The GW Instek PFR-100LGL is a 100W, fanless, multi-range DC power supply (0-50V/0-10A) featuring high-precision output, natural convection cooling, and LAN/GPIB interfaces. It provides 5x rated voltage/current combinations and supports Constant Power (CV/CC priority) operation, making it ideal for low-noise environments. The GW Instek PFR-100LGL (50V/10A/100W) is a fanless, programmable, multi-range DC power supply suitable for R&D, laboratories, and industrial applications requiring low noise and high, flexible output. Its key features include five-fold power output (voltage/current customization), adjustable slew rates, and remote sensing, ideal for motor tests, LED testing, and battery charging. The PFR-100 series, a small and high-performance programmable D.C. power supply, adopts natural convection design to dissipate heat. The fanless structure allows users to focus on their experiments and tests in a quiet environment. Fanless power supply will not suck in dust and foreign objects, therefore, PFR-100 series has a longer life cycle compared with that of power supplies with fan. The PFR-100 series is a power supply with a five-fold rated power that allows users to self-define voltage and current under rated power conditions so as to satisfy them with wider voltage and current operational ranges. PFR-100 series, with rated 100W, provides two models: PFR-100L- maximum output voltage of 50V (at 2A) or maximum output current of 10A (at 10V); PFR-100M maximum output voltage of 250V (at 0.4A) or maximum output current of 2A (at 50V). The PFR-100 series provides front and rear panel output terminals. The front panel output terminal helps users shorten test lead replacement time while conducting adjustment on front panel's function keys. The rear panel output terminal facilitates an easy wiring operation for rackmount assembly. 3U height, 70mm width and 2.5KG in weight have greatly elevated PFR-100 series portability. Furthermore, the multi-drop mode allows users to control up to 31 PFR-100 series without using switch/Hub that help users save the equipment cost.
