Instek PLR 20-18 Low Noise DC Power Supply, 20V/360W

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 series is a hybrid circuit design that 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 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 inrush current while the 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 series. For users who require large output power, the series allows a maximum of 3 same model units in parallel connection to obtain larger output current, and a maximum of 2 same model units in series connection to obtain larger output voltage.

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

The is equipped with an RS-232 interface and also provides optional GPIB&USB (PLR-GU) and USB&LAN (PLR-LU). The program control of a maximum of 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 communications industries.

There are 6 models of the PLR-series. Model number, output voltage, output current, and output power are as follows:
