Regenerative DC Electronic Load

PLZ6000R
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 heatas is typically done, and feeds this power to the AC line, thereby substantially reducing the amount of wasteenergy. PLZ6000R is an environment-friendly electronic load that can contribute significantly to your energy
saving efforts.

Applications
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.

Functions● 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.

● Soft start function
In constant current (CC) mode, this function causes the load
current to rise gradually when the initial load is at 0 V while theload of the load unit is on or when the load of the load unit is turned
on. It allows you to conduct tests under highly realistic loadconditions.
[The soft start time can be selected from the following options - 20,
50, 100, and 200 ms.]

● Sequence function● Regenerated power values recognizable at a glance!
The large-size LCD panel displays regenerated power values inreal time. This makes the energy saving effect much easier torecognize.

This function automatically turns off the load current; it is useful fordischarge tests of batteries and other devices.

the final voltage (UVP) is detected (elapsed time display)• Measurement of the closed circuit voltage after the specified timeelapses from the start of discharge (auto load off timer)

A large-capacity system of up to 30 kW can be built using a parallel
connection configuration with one control unit. (The system may
consist of up to five units - one master unit and four slave units.)

patterns step by step (operation by operation). It enables various
types of waveforms to be simulated. (A maximum of 10 programs
can be created, each consisting of up to 256 steps. Operation
modes, ranges, loop counts, etc. can be specif ied in these
programs.)

● ABC preset memories
Three preset memories A, B, and C are provided to store and readup to three different combinations of an operation mode, a range,and set values.

● Equipped with major interfaces
GPIB, RS232C, and USB interfaces are equipped as standard,
making it easy to integrate the electronic load into a variety oftesting systems.
Support for these interfaces, coupled with the sequence function,
allows you to build diverse types of system.
