SERIES AND PARALLEL CONNECTIONS

(Voltage and Current Allocation Chart for Series and Parallel Operation)

To bring up the overall output power, the PLR-series supports

same model units to be arranged in series operation for the

maximum 2 units or in parallel operation for maximum 3 units.

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 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 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 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 require large output power, the 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 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 to be rack mounted. Other equipment can be directly

placed on top or under to save rack space.

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

(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 communications industries.

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

The series is very suitable for the power supply applications

on D.C. power supply modules, electronic parts and

components, and wafer plating equipment.
