Light, Compact, Low-ripple and Noise
The 720 Watt PLR 20-36 power supply 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.

PLR Series Programmable DC Power Supply Features
The PLR 20-36 has many built-in features, 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 output is turned on); External voltage and current output control and OVP, OCP and UVP functions.

The PLR 20-36 is equipped with RS-232 interface and also provides optional GPIB & USB (PLR-GU) and USB & LAN (PLR-LU). Remote 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.

Additional current can be obtained by connecting a maximum of three PLR 20-36 supplies in parallel; or two units in series to effectively double the voltage output.
