MY‑123 Portable 10A Digital Anti‑Interference DC Resistance Tester Winding

Product Specification

Product Description

The MY-123 Insulation Resistance Tester is composed of large-scale integrated circuits.Thistester features high output power,high short-circuit current value,and multipleoutput voltage levels(each model has four voltage levels).Its working principle is that the internal battery serves as thepower source,generating DC high voltage through DC/DC conversion.The high voltage is outputfrom the E terminal,passes through the test object,and reaches the L terminal,generating a currentfrom the E to the L terminal.This current is then converted and calculated by a divider,with themeasured insulation resistance value displayed directly on the LCD.

Technical Parameters

Product Features

1. High output power,strong load capacity,and strong anti-interference ability.

2. The outer shellis made of high-strength aluminumalloy,with an equipotential protection ring and afour-stage active low-pass filter inside,providing effective shielding against external power frequencyand strong electromagnetic fields.

3. For capacitive test objects,due to the output short-circuit current being greater than 1.6mA,the test voltage can easily rise quickly to the rated output voltage.For low resistance measurements,the voltage drop does not affect measurement accuracy due to the proportional design.

4. This instrument is powered by batteries and does notrequire manual operation.The range can be automatically converted.The clear panel operation and LCD display make measurements very convenient and quick.
