AC & DC Electronic Load

Product Details:

The PLZ-4W Series Electronic Load unit is a multi-functional system designed to offer the highest levels of reliability and safety with operation function of constant voltage, constant current, constant power and constant resistance mode. And its control unit comes with GPIB, RS232C, and USB as standard equipment, available in 5 models. A 0(Zero) V input operating voltage is available in 2 models (PLZ-164WA, PLZ-664WA) which are suitable to meet the testing demands for the Fuel Cell, DC/DC converter, SW Power Supply, and any other devices required for the lower operating voltage application. Model PLZ664WA offers the 132A at 0V input as a largest current rating in its class (33A for model PLZ-164WA). Furthermore, the PLZ-4W features high-speed slew rate when switching, it can be used as simulating load for the characteristic, performance, lifecycle, aging test in the field of application in Automobile electronics, SW Power Supply manufacturer, Secondary Battery.

Features:

• 0(Zero) V input: The 164WA and 664WA of PLZ-4W series permit a load input up to the rated current even when the Input Voltage is set for 0(Zero) V.

• Convenient function for discharging test of cells: The PLZ-4W 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 the load-on mode.

• Booster unit PLZ-2004WB: To achieve a large capacity system at low cost, the PLZ1004W has an expandable option PLZ2004WB as a booster unit. Using one PLZ-1004W as a master unit, a maximum of 4 booster units can be parallel connected. (Max. 9kW, 1800A) Note: PLZ2004WB(Booster unit) can be used for the PLZ-1004W only. It cannot be connected and used with any other model.

• Various Functions: The PLZ-4W Series has equipped with all the same functions of its former type of the PLZ-3W Series, such as the Soft-start Function, Lock Function, Short Function, ABC Memory Function, Set-up Memory Function, Switching Functions, etc.

• GPIB, RS-232C, USB as standard equipment.

Product Details:

PCZ-1000A is an AC electronic load that enables you to perform load simulation for various inverters and transformers. In addition to the resistive loads generally used in tests, it is capable of simulating capacitor-input rectifier loads. The instrument supports input up to 1000W and is equipped with 3 operation modes - Constant Current, Constant Resistance, and Constant Power. Current waveform resembles sine wave can be output constantly without effect by voltage waveform at each mode. Moreover, the instrument is equipped with Crest Factor function that is suitable for simulating current load test for switching power supply. This instrument provides improved operation through CPU control and enables external control and read-back via RS-232C.

Features:

• Parallel operation expands the load capacity.

• Up to 5 units can be operated in parallel (Max. 5 kW, 50 Arms).

• Equipped with tracking operation function.

• Facilitating load tests for peak or harmonic currents helps reduce design and labor time and cost as well as improve the quality of the unit under test.
