Description:
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.
