Kikusui, DC Electronic Load (PLZ-3WH Series )

The PLZ-3WH Series are composed of system electronic loads used either in characteristic or lifetime tests of a variety of DC voltage sources such as switching power supplies and primary and secondary batteries, or as burn in loads. Instruments in the PLZ Series have four operation modes: “constant current“, “constant resistance“, “constant voltage“, and “constant power“. They are also available in four different power ratings, 150 W, 300 W, 600 W, and 1000 W, with a total of eight models available overall. Incorporating a high-performance current control circuit, all instruments provide highly stable, high-speed operation and offer improved operability and multi-functionality through the use of CPU control. These features allow them to simulate actual load tests of power supply units having large transitional changes in their output currents, such as printers and motors. In the constant power mode, these instruments deliver performance in carrying out load tests on alkaline and other types of batteries. Furthermore, PLZ-3WH Series accept DC input voltages of up to 500 V, making it ready for use at high voltages. And when an optional GPIB or RS-232C interface is employed, these instruments can be operated by fully programmable control. In particular, take advantage of a Kikusui-designed multi-channel bus (MCB) to simultaneously control a maximum of 16 instruments per GPIB address or RS-232C port.
