High Efficiency Hipot Test Solution

The Hipot test is one of the major test items in electrical safety testing. All electrical components and products including transformers, capacitors, power supplies, chargers and home appliances require hipot testing.

With more than 20 years experience in developing the instruments for test and measurement, Chroma created the Guardian 19020 multi-channel hipot tester with a brand new architecture. It can measure the hipot leakage current of all channels at the same time and conduct tests on up to 100 DUTs simultaneously.

The Guardian 19020 enables users to save space on the production line since there is no need to purchase multiple Hipot testers. Its one time multi-channel test can increase the efficiency of electrical regulatory testing. It improves productivity and reduces the risks of testing for products that require only hipot testing.

The Guardian 19020 also has powerful functions in Flashover detection and Open/Short Check. It contains several international patents and is the best tool for electrical regulatory hipot testing.

World’s First Sync Hipot Test (Patent Registered)

The Guardian 19020 comes equipped with the world’s first sync hipot test function. A single unit can perform 10 channels sync output and measurements simultaneously. Up to 10 units (master & slave) can be controlled simultaneously to have 100 channels in total. They can be grouped for output to avoid creating voltage difference due to adjacent tests as well as to improve productivity.
