Kikusui PWR Datasheet PDF Datasheet


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.


  • Color liquid crystal display (LCD)
    • High visibility color display. The voltage, current, power, current capacity (Ah) and power capacity (Wh) values are conveniently displayed.
  • Maximum Slew Rate of 60 A/µs
    • Achieving a rise time of 4 µS to reach the rated current of the electronic load. Power supply evaluation demands a fast transient response which the PLZ-5W series achieves with ease.
  • High speed voltage tracking characteristics
    • High speed voltage tracking characteristic in CR mode is perfect for applications such as startup tests for power supplies.
  • Communication interfaces are included as standard
    • LAN (LXI) / USB / RS232C as standard interface. Use a browser from a PC, smartphone, or tablet to access the web server built into the PLZ-5W series for convenient control and monitoring. *GPIB Option
  • Sequence Creation Software Wavy for PLZ-5W (SD023-PLZ-5W)
    • The Wavy for PLZ-5W (SD023-PLZ-5W) is an application software that supports sequence creation and the operation of the Kikusui power supplies and the electronic load. The "Wavy" software allows you to create and edit sequences visually using a mouse without programming knowledge. It enables you to control the electronic load for such monitoring the voltage and current, logging and so on.
  • Arbitrary I-V characteristics (ARB) mode
    • In ARB mode arbitrary I-V characteristics can be set by entering multiple I-V points (voltage and current value set points). From 3 to 100 points can be registered and the space between two points is automatically linearly interpolated. This mode can be used for simulation of LED loads and other DUT's with non-linear characteristics.
  • Booster (PLZ2405WB)
    • Achieving 2400 W in "2U" size. Connecting up to 4 booster (PLZ2405WB) units with the master (PLZ1205W) increases the maximum system capability to 10.8 kW 2160 A. The optional parallel cable (PC01-PLZ-5W) is reguired to connect between the master and slave/booster units. *PLZ2405WB is a dedicated booster for PLZ1205W. It cannot be used with any other model.
  • Parallel operation
    • Multiple units of the same type can be connected in parallel. Without using boosters, you can connect up to five units of the same model in parallel, including the master unit (max. 6 kW, 1200 A). In the parallel connection configuration, one control master operates with one or more slave units, enabling you to control the entire system and view the sum of the combines data on the master unit’s panel. To connect the units requires the use of as many optional parallel cables (PC01-PLZ-5W) as the number of units to be connected. *The PLZ2405WB (Booster) comes with 1 pc. of parallel operation cable (PC01-PLZ-5W).
  • PLZ-5W SR Large scale system SR Series (Smart Rack)
    • The compact, large scale system, SR (Smart Rack) Series is available. The input power is available in 6 kW, 10.8 kW, 15.6 kW, and 20.4 kW. The maximum input current is 2160 A. (*1200 A for PLZ6005W)


PLZ-334WL - extrem schnelle, elektronische DC Last von Kikusui


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.
