Leakage Current Testing According to IEC60990, IEC60335, and other Safety Standards
To ensure the safe use of electrical products, electrical safety tests such as insulation resistance, withstand voltage, ground resistance, and leakage current must always be conducted. Hioki Leakage Current Testers comply with laws and standards regarding medical electrical equipment as well as non-medical electrical equipment, and can be used to measure leakage current in all types of electrical products from computers to medical equipment.
The ST5541 provides support for standard-compliant
networks (excluding medical-use electrical devices).
Note: The photograph portrays the Japanese version of the product. Other countries’ versions of the product lack the outlet on the front panel.
Note: For applications involving leak current measurement of medical-use electrical devices, use the ST5540.
Low-cost solution for complying with standards governing general-use electrical devices
• 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.
• Communications functionality and external I/O support allow automatic testing on production lines
■ Basic specifications (Accuracy guaranteed for 1 year)
