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/μs*1 and a minimum setting resolution of 10 μA*2, 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. What’s 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*3 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, RS232C, 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.
