GW Instek PLR20-18
Programmable Power Supply / Source
Programmable, 0 ~ 20 V, 0 ~ 18 A, 360 W, RS-232

GW Instek launches the new generation PLR series programmable switching D.C. power supply. The single power output ranges are 360W and 720W. The series comprises 6 models and the voltage ranges are 20V, 36V and 60V.  The PLR series is a hybrid circuit design which incorporates front stage switching and rear stage linear architectures. The unique advantages of this design benefit from the combination of both switching and linear structures. The front stage switching structure can effectively reduce size and weight, and the rear stage linear structure can maintain lower ripple voltage, lower ripple current, and faster transient response.

The PLR-series features many functions, including three sets of user-defined preset function; programmable automatic output off timer function; programmable sequence function; CV, CC priority activation functions (prevent overshoot and in rush current while output is turned on); External voltage and current output control and OVP, OCP and UVP functions. The above functions are built-in. Users do not have to pay for any extra costs.

The flexible allocation is one of the advantages of the PLR-series. For users require large output power, the PLR-series allows maximum 3 same model units in parallel connection to obtain larger output current, and maximum 2 same model units in series connection to obtain larger output voltage.

The PLR-series takes the consideration of the integration between its rack and other systems. Hence, the heat dissipation design adopts front air inlet and rear air outlet (there is no air outlet on the top, bottom, and on the both sides). The optional dedicated rack mount adapter (GRA-427) is for PLR-series to be rack mounted. Other equipment can be directly placed on top or under PLR-series to save rack space.

The PLR-series is equipped with RS-232 interface and also provides optional GPIB & USB (PLR-GU) and USB &L AN(PLR-LU). The program control of maximum 32 units can be realized by Local Bus no matter which interface is utilized. Additionally, the PLR-ARC interface not only provides external voltage and external resistance control but also meets the requirement of PLC control.

The PLR-series genuinely meets users' requirements of the new generation DC power supplies. The series, completely simplifying and expediting system development processes, is suitable for the R&D, design verification, and manufacturing of the semi-conductor equipment, automobile, component and communication industries.

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. GW Instek's reputation has been built upon the philosophy of integrity, quality, and creativity as well as the accumulation of years of experience.
