All standard tests available for medical electrical equipment and general electronic equipment:
While common electronic devices, including medical devices, have insulation designed to protect users from electric shock, too much time can lead to deterioration of insulation. ST5540 series meet the standards of detection of deterioration, can be used for leakage current test. (ST5540 can be used for medical equipment)
Change of measurement method to shorten operation time:
When the original model (leakage current tester 3156) is used for specific standard test, the power supply of the equipment under test needs to be cut off. The ST5540 can be tested without cutting off the power supply, thus shortening the operation time.
Up to rated current 20A, expanding the range of application:
Meet the requirements of customers who need on-site use, so that the new product's maximum rated current can reach 20A (original model 15A). Because it can adapt to larger current, it can be used in the leakage current test of new products such as production equipment and home appliances. Moreover, the voltage can reach 240V (maximum 264V).
