The PLZ153W is a programmable, microprocessor-based, 150w Electronic Load. It is rated for up to 120V and 30A. It features four operating modes: constant current, constant voltage, constant resistance, and constant power. The PLZ153W is simplicity itself to use. The jog/shuttle knob ramps output parameters up or down while readback is displayed on the backlit LCD display. Output connections are via knurled screws on the front panel or through-bolt on the rear panel. The PLZ153W is ideal for testing of dc power supplies and batteries. An IEEE-488 interface is available optionally for remote control applications.
