Fanless Multi-Range DC Power Supply

GWInst PFR 10023 January 2023 - GW Instek introduced the PFR-100 series, a small and high-performance programmable DC power supply, which 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.
