HIOKI ST5540 and ST5541 Leak Current Tester
Leak current measurement is an essential part of electrical safety for medical-use electrical devices (with ST5540) as well as general electrical devices (with ST5541). Electrical safety tests such as insulation resistance, withstand voltage, ground resistance, and leakage current must always be conducted provide safety for the use of electrical products. The HIOKI ST5540 consists of measurement networks that simulate the human body and a high-frequency volt meter, and is also capable of switching power supply polarities and making measurements under simulated single fault conditions in equipment under test. The HIOKI ST5541 provides support for standard-compliant networks (excluding medical-use electrical devices).
- Leakage current testers, comply with laws and standards regarding medical electrical equipment as well as non-medical electrical equipment.
- Can be used to measure leakage current in all types of electrical products from computers to medical equipment.
- Uninterrupted polarity switching function dramatically reduces cycle time.
- Support for rated currents up to 20 A gives the instrument more than adequate capability for testing products designed to comply with new standards.
- Touch panel features simple, interactive operation.
