The Headache of Imprecise, Low Quality Load Banks (variable resistors).
Configuring load banks used to be a chore, but now it’s a breeze for anyone to configure a load precisely at the twist of a dial.

The Solution

Key Aspects of the Solution

  • Kikusui’s PLZ-5W range of electronic loads allows the desired resistance to be set at the flick of a switch.

  • The PLZ-5W range supports many different modes of operation for precision measurement.

  • Offering flexibility, the PLZ-5W range features models that satisfied the requirements of other divisions as well.

Even Simpler Than We Imagined!

The engineer was at his wit’s end. At around this time, however, a vendor told him that if he was looking for an electronic load, he couldn’t go past the Kikusui PLZ-5W series for range and ease of use. When the engineer went to the PLZ-5W website, he was impressed by the device’s specifications, and immediately made inquiries. A few days later, the Kikusui specialist whom he talked to visited him with a demo PLZ-5W and provided him with a detailed explanation of the electronic load.

“The first time I picked up the PLZ-5W, I was amazed to realize that it allows anyone, regardless of experience, to set their desired resistance simply by flicking a switch. The PLZ-5W range offers a range of modes, including constant voltage, constant current, and constant power, and is packed with features that are ideal when performing aging tests on fuel cells. The range also has an intuitive color display for ease of use.”

Normally when emulating a high capacity fuel cell, several units are connected in parallel to increase the size of the load, a complex job that requires complex configuration. With the PLZ-5WH2 series, however, configuration is a breeze, and this makes these loads suitable for testing everything from domestic appliances to automotive fuel cells, a feature that was rated highly by other divisions. The engineer was also relieved to learn that the PLZ-5WH2’s sister model, the PLZ-5WZ, supports precision impedance measurement in the range of 100Hz to 10kHz, and that therefore the requirements of the quality assurance division could be met.

The engineer proceeded to subject the demo model to repeated tests. The PLZ-5W’s capabilities made him wish he had found out about the range sooner.

All the client’s divisions now use electronic loads from the PLZ-5W series, which have enabled the client to measure more precisely and efficiently.
