PLZ-U Series

Modular Multifunction DC Electronic Load (CC/CV/CR/Zero volt input) : 4 Models

Outline

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 RS-232C 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.

*3 For the PLZ70UA

Features

  • Compact, lightweight body
    The electronic load system is as wide as a 19-inch rack with a height of 3U. Weighing about 11 kg when configured for three channels or about 17 kg when configured for five channels, the system is compact, lightweight and space-saving.
  • High-speed response
    In constant current mode, the electronic load is capable of offering high-speed response at a slew rate of 2.4 A/µ s at the rising and falling edges of the current (equivalent to about 10 µ s when converted to the rise and fall times; in the case of PLZ150U).
  • High precision and high resolution
    The built-in three-range configuration provides both wide dynamic range and high precision. The voltmeter, ammeter and wattmeter functions that display values using up to five digits each and a minimum setting resolution of either 10 µA (PLZ70UA) or 20 µA (PLZ150U) are implemented.
  • Variable slew rate
    In constant current or constant resistance mode, the slew rate can be changed continuously.
  • 0(Zero)V input
    The PLZ70UA model operates even when the input operating voltage is 0(Zero)V.
  • Multi-channel system
    PLZ-50F may be configured with up to five channels, and PLZ-30F may be configured with up to three channels. Isolated from each other, the channels can operate both independently and in synchronization. Different models of load units (PLZ150U and PLZ70UA) can be housed in a single frame.
  • Frame control
    You can connect two or more frames and use one of them to control the others (up to five frames can be connected at a time). This enables you to turn on or off the load and call preset values.
  • Parallel operation for increased capacity
    Up to five load modules may be operated in parallel, provided that adjacent load modules are of the same model.
  • Sequence function to enable load simulations
  • External control functions

PLZ6000R

Posted on by Tn-tech Admin

6kW Regenerative DC Electronic Load (CC/CR/CV/CP/CC+CV/CR+CV)

Outline

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.

Features

  • Power regeneration efficiency of up to 90% (at rated power)
    The use of a proprietary switching technology (patent pending) provides high power regeneration efficiency – from 85% or more at one-third of rated power (2000 W) to a maximum of 90% or more. This energy saving feature greatly reduces the electronic load’s environment impact on your plant and it is not necessary to equip special cooling system such as water cooling method to supress the heat generation.
  • No necessity of special cooling system such as water cooling method
    Please view the movie about comparison with conventional E-load. The movie will help your understanding about effect of PLZ6000R.
    • Aging and evaluation testing for DC/DC converters and various types of power supplies
    • Evaluation and durability testing for alternators and motor generators
    • Discharge testing for different types of batteries (lead, lithium, and assembled batteries)
    • Dummy load testing for equipment powered by natural energy (solar cells and wind power generation)
    • Evaluation testing for fuel cells and stacks
    [Note] This product is intended for in-plant power generation only. (It does not feed its generated power back to the electric power system.) This product cannot be used unless 5.4 kW or more of power is consumed by each power distribution system per one unit.
