Exploring Guardian Multi-Channel Hipot Tester

Guardian Multi-Channel Hipot Tester

Chroma 19020

Measure the hipot leakage current of all channels at the same time and conduct tests on up to 100 DUTs simultaneously

Mode (Model Specific)

AC or AC / DC / IR

Channels

10 (up to 100)

Output Capability

AC: 0.05kV~6kV
DC: 0.05kV~8kV

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.

Synchronous Hi-Pot Test

One issue frequently encountered when testing multiple DUTs for Hipot is the lack of ability to synchronize the voltage output. When planning for a production line or automation, minimizing facilities and optimizing space are often utilized in the plant. This results in the distance between two DUTs being quite small. The Chroma 19020 synchronizes the output signal preventing high voltage differences on the adjacent two ends. This not only extends the life of production equipment but can also reduce the occurrence of judgment errors.

Flashover Detection

As with other Chroma EST Series scanners, the 19020 has a Flashover detection function. Flashover is the electrical discharge generated by a high electrical field inside or on the surface of insulation material that causes the DUT to lose its insulation characteristics and form a transient or discontinuous discharge. It can cause a carbonized conductive path within the insulation, or even damage the product under test. Flashover cannot be detected by only monitoring leakage current. The change rates of test voltage or leakage current are monitored to detect flashover as its detection is one of the most indispensable test items for electrical safety testing.

Chroma 19020 comes equipped with the world’s first sync hipot test function. One single unit can operate 10 channels simultaneously with synchronized output and measurements. Up to 10 units (master & slave) can be linked to have 100 channels in total. These can be grouped for output as to avoid creating voltage differences caused by adjacent tests as well as to improve productivity.
