The PLZ-4W Series offers high-performance DC electronic loads capable of operating in six modes: constant current, constant resistance, constant voltage, constant power, constant current + constant voltage, and constant resistance + constant voltage.
In addition to offering high-speed response at a maximum slew rate of 16 A/uS and a minimum setting resolution of 10 uA, the system features a variety of functions including soft start, variable slew rate, a switching function, an ABC preset memory function, 100 setup memories, and a sequence function. Whats more, timer functions combined with time/voltage measurement functions allow you to measure battery discharge characteristics.
Also provided is a master/slave parallel operation capability that makes it possible to expand the current and power capacities according to the output of the device under test. The PLZ1004W can handle up to 9 kW and 1800 A through the use of dedicated booster units (PLZ2004WB).
For communication, the system is provided with GPIB, RS-232C, and USB 2.0 interfaces as standard. Each of these interfaces supports IEEE 488.2 as well as the Standard Commands for Programmable Instruments (SCPI), developed for testing and measuring instruments]
