The current trend in semiconductors is towards lower voltages and higher speeds. This trend places similar demands not only on the components of semiconductor power units, such as switching power supplies, batteries, and DC/DC converters, but also on the electronic loads used for testing. Research and development in the field of fuel cells, which are expected to become an eco-friendly source of energy, demands electronic loads that allow a current to flow even at 0 V, as well as load systems with expandable capacity for testing stacks of cells. The PLZ-4W Series of electronic loads has been developed to satisfy all these demands.

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 and a minimum setting resolution of 10 μA, for the PLZ164/164WA, 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 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 N1800 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
