Instek PFR-100L [PFR-100L] (0~50V/ 0~10A/ 100W) Fanless Multi-Range DC Power Supply

The GW Instek PFR100L is a small high-performance programmable D.C. power supply that adopts a natural convection design to dissipate heat. One of the unique features of the PFR-100L is the fanless cooling system. This allows users to focus on their experiments and tests in a quiet environment. Additionally, the PFR-100L will not suck in dust or foreign objects extending the life of the power supply. The PFR100L is rated 100W with a maximum output voltage of 50V (at 2A) or maximum output current of 10A (at 10V).

The PFR-100L provides front and rear panel output terminals. The front panel output terminal helps users shorten test lead replacement time while conducting adjustments on the front panel's function keys. The rear panel output terminal facilitates an easy wiring operation for rackmount assembly.

The PFR100L has multiple features to meet test requirements for different load characteristics. The CC priority mode can be applied for device under test (DUT) with diode characteristics to prevent the DUT from being damaged by inrush current. A slow rise time for voltage can also protect the DUT from inrush current, especially for tests on capacitive load. When the power is off, or the load is disconnected, the activation of Bleeder circuit control will allow the bleeder resistor to consume the filter capacitor's electricity. Without the bleed resistor, the power supply's filter capacitor may still have electricity that is a potential hazard. For automatic testing equipment systems, the bleeder resistor allows the PFR100L to rapidly discharge to prepare itself for the next operation
