I. Overview

The HG2672 withstand voltage tester is a basic withstand voltage tester with excellent cost performance. The output voltage is adjusted through a voltage regulator and has the characteristics of high reliability and high durability. High-brightness LED digital tubes are used to display test time, voltage, current, and breakdown current and voltage values can be displayed in real time; alarm current values can be preset continuously and arbitrarily; test time is displayed using three-digit digital tubes, and the minimum resolution of time is 0.1 s, the time preset range is 0.0s~999s. Equipped with signal input and output interfaces required by PLC, it can easily form a comprehensive test system with PLC. It can quickly and accurately measure the withstand voltage strength of electronic components, household appliances, insulation materials, instruments, lighting appliances, and electric heating appliances.

This tester complies with the following standards:

     Household appliance standards (IEC6035, GB4706.1-2001), GB4706.1-1998);
     Lamp standards (IEC60598-1-1999, GB7000.1-2000);
     Information standards (GB8898-2001, GB12113.GB4943-2001, IEC60065, IEC60950);
     Medical standards (IEC601-1-1998, GB4706.1-1998, GB4793.1-2007), etc.
