Datasheet

Kikusui’s DC Electronic Loads prove to be a popular choice for fuel cell and low voltage power supply testing. Kikusui currently have a choice of two Electronic Loads that are equipped to sink current at zero volts. The PlZ164WA Bench type DC Load and the PLZ70UA modular electronic load.

The PLZ-164WA 0 to 150V, 33A, 165W Electronic Load unit is a high-performance DC electronic load, capable of operating in five modes: constant current, constant resistance, constant voltage, constant current + constant voltage, and constant resistance + constant voltage. GPIB, RS232C and USB are standard.

Sequence patterns can be saved in the built-in memory. In the sequence program, 10 normal sequences and 1 first sequence can be saved. 256 steps of normal sequences and 1024 steps of the first sequence can be saved in each program.

The PLZ164WA is also equipped with a convenient function for discharging cells. The Electronic Load can measure the time from load-on to load-off. When combined with under voltage protection (UVP) function, the time from when the battery discharge is started until the battery voltage falls to the cutoff voltage can be measured. Also, you can set the timer so it will load-off automatically after a specified time elapses from load-on mode. Once this timer is set, the input voltage value immediately before load-off is displayed, so it is possible to measure the closed circuit voltage after a specified time elapses from the start of discharging the battery.

The PLZ-70UA 0 to 150V, 15A, 75W Modular DC Electronic Load. The load system consists of load modules and a frame. Designed to offer the highest levels of reliability and safety with operation function of constant voltage, constant current, constant power and constant resistance mode. The load modules are inserted into the frame that also serves as a control unit. The PLZ-30F frame can accommodate up to three load modules, while the PLZ-50F frame can accommodate up to five.

The system features a variety of functions including soft start, variable slew rate, a switching function, ABC preset memory function, four setup memories, and a sequence function. What's more, timer functions combined with time/voltage measurement functions allow you to measure battery discharge characteristics.
For communication, the system is provided with GPIB and RS-232C interfaces as standard.
