Hioki ST5541

Leak Current HiTester JIS, UL IEC Standard

Introducing a leak current measuring instrument that complies with the IEC 60601-1 standard (3rd edition, with the ST5540), the ST5540 series feature an improved measuring method and dramatically faster cycle times, thanks to its uninterrupted polarity switching. The new devices support rated currents of up to 20A, making it more than ideal for use with products built to new standards.

In order to prevent the danger of electric shock, electrical devices use power supplies that are isolated from parts of the device that may come into contact with the body. However, it is impossible to achieve infinite insulation resistance. Some leak current always exists, and its magnitude changes as the insulation degrades over time. The LEAK CURRENT HiTESTER ST5540/ST5541 provides an easy-to-operate solution for measuring leak current in electrical devices, making it eminently suitable for use in an extensive array of applications, ranging from production lines to equipment maintenance and inspections.
