JYL-200A Loop Resistance Tester
Darui Electric recommends:
Product Introduction:
The JYL-200A Loop Resistance Tester is designed by combining high-frequency switching power supply technology and digital circuit technology.
The intelligent loop resistance tester is suitable for measuring the loop resistance of switch control equipment. Its test current adopts the DC 100A and 200A recommended by national standards. The loop resistance can be directly measured at currents of 100A and 200A, and the final test results are displayed on a large-screen LCD, with functions such as data storage, output printing, and time setting. Additionally, 50A and 150A gears are available for user selection. This instrument features accurate measurement, stable performance, and meets the requirements for on-site high-voltage switch maintenance in power and power supply departments, as well as loop resistance testing in high-voltage switch factories.
