Contact current tester

1、IDI6821-E Series Contact Current Tester, specially designed for leakage current measurement of medical devices, household, and commercial electrical appliances. It can perform AC and DC leakage current tests, with a variety of detection methods and testing points. When testing a specific electrical product, different simulated impedances can be selected to measure leakage current to ground, surface leakage, and inter-surface leakage. It can also simulate the input power supply status, performing tests such as normal live-zero wire testing, live-zero wire reverse connection testing, missing zero wire testing, and missing ground wire testing. This series of testers is compatible with various Chinese and international standards for leakage current, including but not limited to product design and manufacturing standards, metrology standards, and product certification standards. Multiple models are available for selection based on actual testing needs; the tester’s measurement capabilities and industrial design are at the forefront of the industry.

According to the working status of the tested equipment, this series of testers can perform static leakage current measurement and dynamic leakage current measurement.Full protection functions: various abnormal protection mechanisms such as OPP, OCP, OutError, OFL, GF, ARC, and multiple parameter judgment conditions such as U_HI, U_LO, P_HI, PF_HI.

Static leakage current measurement: The tested equipment is in a non-operational state, with its power switch turned on. Apply 1.06 times the rated voltage and measure the leakage current values from the phase line and neutral line to the chassis or ground, respectively.

Dynamic leakage current (leakage current at operating temperature) measurement: During measurement, the load should be powered through an isolated power supply (or an isolation transformer), and the leakage current values of the phase line and zero line to the chassis or ground should be measured separately.

2、Industry applications:

Home appliances, commercial appliances, 3C consumer electronics, medical devices, lighting fixtures, charging piles, electric vehicles, rail transit, power electronic components, power equipment, energy industry, motor coil products, power tools, third-party laboratories and other certification and quality inspection agencies.

3、Equipment selection:

4、Basic knowledge of electrical safety performance:

Leakage current test: The current unrelated to operation generated by the power supply of the tested product through insulation or distributed parameter impedance is called leakage current. For Class I appliances, it refers to the current that passes through or crosses the insulation into the protective grounding wire under the applied test voltage. Depending on the testing site, it can be distinguished as earth leakage, surface leakage, or inter-surface leakage; the analyzer has multiple built-in simulated networks to mimic the structure, materials, usage environment, and operator’s body impedance of the tested product.
