The ST5541 features an improved measuring method and dramatically faster cycle times, thanks to their uninterrupted polarity switching. These
ST5541 Leak Current Tester supports rated currents of up to 20A, making them 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 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. |
