SXHL-200A Loop Resistance Tester

Product Introduction

SXHL-200A Loop Resistance TesterIt is designed based on the power implementation standard DL/T845.4-2004 of the People's Republic of China, using a combination of high-frequency switching power supply technology and digital circuit technology. It is suitable for measuring the circuit resistance of switch control equipment. The test current adopts the recommended DC 100A and 200A according to national standards. The circuit resistance can be directly measured at 100A or 200A, and the test results are displayed in numbers. The instrument measures accurately and has stable performance, meeting the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing for power and supply departments.

SXHL-200A Loop Resistance TesterSuitable for high-precision measurement of contact resistance (loop resistance) of high-voltage switches, and also applicable to other occasions that require high current and micro resistance measurement.

performance characteristics

1. High current: By adopting new power supply technology, it can continuously output high current for a long time, overcoming the drawbacks of instantaneous current in pulse power supplies. It can effectively penetrate the oxide film of switch contacts and obtain good test results.

2. Strong anti-interference ability: Under severe interference conditions, the last digit data of the LCD screen can be stable within ± 1 word range, with stable readings and good repeatability.

3. Long service life: All use high-precision resistors, effectively eliminating the influence of environmental temperature on measurement results, and the use of connectors enhances anti vibration performance.

4. Convenient to carry: small size and light weight.
