PLZ-5W/5WZ Series

The PLZ-5W Series high performance electronic load is the successor to the highly respected PLZ-4W series, whilst still retaining the same high specification and build quality. Advances include a high visibility color display, low voltage operation from a minimum of 1 V to a maximum of 150 V. Programmable profiles of voltage/current can be applied (using the new ARB function, as used in LED/solar testing) in addition to the inherited 6 modes of operation: Constant Current, Constant Resistance, Constant Voltage, Constant Power, Constant Current + Constant Voltage, Constant Resistance + Constant Voltage.
Equipped with a high-speed response feature boasting a maximum slew rate of 60 A/μs (PLZ1205W) and a minimum setting resolution of 10 μA (PLZ205W). Additional features of the PLZ-5W series include: Soft-start function, variable slew rate, selectable response (CV/CR mode), switching function, ABC preset memory, 20 user-defined set-up configurations, and a sequence operation function. The advanced high-speed response makes the PLZ-5W ideal for the development and testing of today's modern power supplies that require variable high-speed current changes. This advantage extends to the testing of current clamps/transducers.
The PLZ-5W Series is available in 4 standard models which can be incrementally extended by adding additional booster units (PLZ2405W) to achieve a maximum of 10.8 kW / 2160 A DC electronic load.
The following communication interfaces are installed as standard: LAN (LXI compliant), USB, RS232C and analog control. An optional GPIB interface is available.

PLZ-4WL Series

While the PLZ-4WL series succeeds to the superior operability of our conventional model of the PLZ-4W series, the PLZ-4WL series realizes the high speed rise and fall time (slew rate of 50A/µs.) in the range of low voltage with large current. The PLZ-4WL offers six operation modes, and equips with various features such as sequence operation, switching operation, soft-start function, and time and voltage measurement. The PLZ-4WL applies not only for the conventional load test of the CPU power supply, but also it can be applied to even faster current response test. In addition, the PLZ-4WL is a space-saving design (about 50% less volume of the conventional model) that can save the facility space of the testing site, and it can be applied for the single cell testing of the large scale rechargeable battery.

PLZ6000R

PLZ6000R is a DC electronic load that regenerates load power to the AC line. Regular electronic loads consume load power by having semiconductor devices convert it into heat. By contrast, PLZ6000R converts load power into reusable electric power, rather than converting it into heat as is typically done, and feeds this power to the AC line, thereby substantially reducing the amount of waste energy. PLZ6000R is an environment-friendly electronic load that can contribute significantly to your energy saving efforts..

PLZ-U Series

The current trend in semiconductors is towards lower voltages and higher speeds. This trend places similar demands on both the components of semiconductor power units, such as switching power supplies, batteries and DC/DC converters, and also on the electronic loads used for testing. Also, a growing number of users with a need for multiple-output power units and easy channel reconfiguration are calling for plug-in type electronic loads that can be easily configured to support multiple channels. The advent of an electronic load system that satisfies all these needs has been long awaited. It was against this background that we developed the PLZ-U Series of electronic loads.
The PLZ-U Series of compact and high-performance modular electronic loads is capable of operating in five modes: constant current, constant resistance, constant voltage, constant current + constant voltage, and constant resistance + constant voltage. The load system consists of load modules and a frame. 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 load modules can be operated in parallel, so that the current capacity or power capacity can be changed easily, from 75 to 750 watts*1, as needed for the device under test. In addition to offering high-speed response at a maximum slew rate of 2.4 A/ µs*2 and a minimum setting resolution of 10 µ A*3, 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 RS232C interfaces as standard. Both interfaces support IEEE 488.2 as well as the Standard Commands for Programmable Instruments (SCPI) commands, developed for testing and measuring instruments.
