The PXZ series of highly efficient, reliable, high-capacity regenerative electronic loads has a rated power of 20 kW in 3U. In addition to the constant-current, constant-resistance, constant-voltage, and constant-power operat- ing modes, this series has an I-V character-istic function that allows the user to set arbi- trary I-V characteristics for each CC and CV operating mode. The series is also equipped with various functions, such as sequence, pre-charge, synchronous operation, pulse, sine, and VMCB functions. LAN, USB, and RS232C communication functions are in- cluded as standard, allowing easy integration into various evaluation systems. The PXZ series is highly scalable, and its capacity can be increased up to 500 kW when operating in parallel (up to 25 units).

PLZ-5W/5WZ series
PLZ-5W/5WZ series
The PLZ-5W series electronic load is the successor of the highly respected PLZ-4W that continues the series tradition of high specification and excellent build quality.
New improvements include a user- friendly LCD color display and a wide voltage range from 0.25 V to 150 V. Custom voltage/current profiles can now be programmed using the new ARB function, ideal for LED driver and solar panel testing. The PLZ-5W now includes 6 basic modes of operation (CC, CR, CV, CP, CC+CV, & CR+CV) for optimal flexibility in any test facility.

PLZ-5WH2 Series
PLZ-5WH2 Series
The PLZ-5WH2 high power DC electronic load series is where durable, reliable ingenuity meets a multifunctional, high- power design. Providing 5 varieties of power range line-ups, from 1 kW a bench top style model to high power model that can sink up to 20 kW of power in a single unit. Possible you can select the optimal capacity according to the load. Load simulation can be achieved faster than ever before thanks to the reliable, high speed design of the PLZ-5WH current control circuits. Accurate current measurements can be made with an extremely high-setting resolution. A color LCD display allows for highly visible, user- friendly front panel operation. RS232C,USB, and LAN digital interfaces are included as standard for simple integration into any system.

PLZ-4WL Series
PLZ-4WL Series
High Speed-Large Current DC Electronic Load (50A/μs)
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 6 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 is capable 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.

PLZ-U Series
PLZ-U Series
The PLZ-U Series provides a set of compact, high-performance multi-channel electronic load systems capable of
operating in three modes – constant current, constant resistance, and constant voltage. Adopting the modular
(plug-in) design, the Series consists of four models – two frame models and two load unit models. The PLZ-30F
frame can configure the load units up to three channels, and the PLZ-50F frame can configure up to five channels.
Two load unit models are available, the PLZ-70UA (75-watt load that operates even at 0 V) and PLZ-150U (150-watt
load that operates from 1.5 V up). Load units can be operated in parallel to increase the current capacity or power
capacity. By combining different models of load units and frame, the power capacity can be changed from 75 W to
750 W (when five PLZ150U units are mounted in a PLZ-50F frame).
