PLZ-405WZ

400W IMPEDANCE MEASUREMENT SYSTEM
Sales price $ 8,064.00
(Excluding GST)

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.

Impedance measurement system PLZ-5WZ Series:

  • The PLZ-5WZ series allows for easily configured impedance measurements with dedicated impedance measurement software.
  • Impedance measurements are made during discharge, allowing for real-time measurement of impedance values from the DUT.
  • Capable of R, jX, θ, and Z measurements.
  • Measures AC frequency from 100 Hz - 10 kHz (seven fixed settings) and signal levels can be set arbitrarily.
  • Equipped with a voltage slope correction function that minimizes the effect of voltage slope during during battery discharge tests.
  • Zero adjustment function allows for increased accuracy during critical impedance measurements.
  • Measurement results and graphical information can be copied directly from the application software to programs like Excel.

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.
