The PFR-100 series, a small and highperformance 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); PFR100M- 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.

The LAN interface for PFR-100 is Ethernet port. PFR-100 also has a built-in web server and intuitive user interface. Users, via general browsers including Internet Explorer, Mozilla Firefox or Android cellular phones, can monitor PFR-100's test and measurement anywhere. Users not only can remotely monitor PFR-100 via internet, but also remotely observe and adjust their operating PFR-100s in the lab from your home. The outputs of PFR-100 series can be monitored including OVP, OCP, UVL; and the system information can be checked such as unit's serial number, firmware edition and internet setting. Users can remotely adjust PFR-100 settings, including output voltage/current, the slew rate for voltage/current, Bleeder circuit control, OCP, delayed time for output voltage and Buzzer settings.

The PFR-100 series provides special functionalities to meet test requirements for different load's characteristics. The CC priority mode can be applied for DUTs with diode characteristics to prevent DUT from being damaged by inrush current. A slow rise time for voltage can also protect DUT from inrush current, especially for tests on capacitive load. When power is off or load is disconnected, the activation of Bleeder circuit control will allow the bleeder resistor to consume filter capacitor's electricity. Without the bleed resistor, power supply's filter capacitor may still have electricity that is a potential hazard. For automatic testing equipment systems, the bleeder resistor allows PFR-100 series to rapidly discharge to prepare itself for the next operation.

Founded in 1975, Good Will Instrument Co., Ltd was the first professional manufacturer in Taiwan specializing in electrical test & measurement instruments. GW Instek began as a manufacturer of power supplies and quickly expanded into the development of high precision electronic test and measurement instruments.

After decades of experience in the test and measurement industry, GW Instek has grown to become one of the important manufacturers and developers of test and measurement instruments worldwide. Today GW Instek has more than 300 product items, ranging from oscilloscopes, spectrum analyzers, signal sources, basic test & measurement instruments to video surveillance systems. GW Instek has also seen its present growth internationally. With headquarters located in Taipei, Taiwan, GW Instek has subsidiaries in mainland China, America, Japan, Korea, Malaysia, Europe, and India; its products are sold to more than 80 countries worldwide.

With a strong focus on high quality, economical measurement solutions for the educational and industrial manufacturing markets, Good Will Instrument has developed a solid brand image and reputation for reliability, integrity and innovation. From its inception, GW Instek has dedicated itself to becoming a professional electronic test and measurement designer and manufacturer, resulting in a number of national awards and the trust of customers world-wide; In 1993 Good Will Instrument became ISO 9002 accredited and the following year won the Highest Honor of National Outstanding SMEs (small and medium enterprises) Award from the Taiwanese Ministry of Economic Affairs. In 2000, Good Will Instrument went public on the Taiwan Stock Exchange.

GW Instek has been a byword for quality electronic test & measurement instruments due to its decades of experience in R&D, marketing and manufacturing.
