Product Details

HIOKI ST5540 Leak Current HiTester

Leak current measurement, an essential part of electrical safety (Medical-use Electrical Devices/For Standard- and Regulation-compliant)

IEC 60601-1: (2005) 3rd Edition-compliant. The ST5540 complies with JIS, IEC, and UL standards governing medical- and 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.

Note: Always use an isolation transformer when measuring leak current for medical-use electrical devices. The ST5540 does not include an isolation transformer. When measuring medical-use electrical devices, use a step-up isolation transformer or similar component operating at 110% of the rated supply voltage as the power supply for the device under test.
