KD7440 program controlled voltage tester provides ground resistance, insulation resistance, AC voltage resistance, DC voltage resistance, normal contact current (dynamic leakage), fault state contact current (static leakage), low voltage start, power and other testing functions. In order to improve the test efficiency, the KD7440 program controlled voltage tester provides multi-functional joint test solutions such as grounding + alternating resistance, grounding + power, alternating resistance + power, grounding + alternating resistance + power.
The KD7440 programmable Voltage tester continuously monitors the temperature of the internal power devices. When the internal power device temperature reaches the analyzer protection limit of 85 ° C, the analyzer terminates the test.
The switching time between test items and the power polarity switching time of the leakage current of the KD7440 program controlled voltage withstand tester are both < 0.1s. The switching time includes the protection time of functions such as discharge protection of the test item.
KD7440 program controlled voltage tester, some high-end models support built-in spot check tooling, spot check tooling use and metering, see the analyzer embedded in the help document.
