MS-3126A Insulation Resistance Tester (30kV)
This intelligent high-voltage insulation resistance tester features 9 selectable voltage ranges: 500V, 1000V, 2500V, 5000V, 10000V, 15000V, 20000V, 25000V, and 30000V. It offers a maximum test range of up to 30 TΩ and includes a manual voltage adjustment function.
● Designed in strict compliance with safety standards.
● Insulation resistance range: 30 TΩ at 30 kV.
● Adjustable short-circuit current, with a maximum output of 5 mA (customized versions with a short-circuit current of up to 10 mA are available).
● Automatically displays test values for the Polarization Index (PI) and Dielectric Absorption Ratio (DAR); also capable of measuring leakage current and capacitance.
● Superior anti-interference performance: the instrument maintains test accuracy even when subjected to interference currents reaching 2 mA.
● Rapid discharge for capacitive test objects: when testing cables, no manual discharge is required, as the instrument performs a rapid, automatic discharge.
● Dual Power Supply Modes: Powered by a lithium-ion battery with an endurance of up to 4 hours (under a 30,000V no-load condition).
The unit supports charging while in operation; in the event of a power outage, it automatically switches from AC mains power to battery power. ● Fully Chinese-language display with Chinese operational prompts; simple, clear, and features an analog bar graph for insulation resistance.
● Digital filtering function: Use the filtering feature to mitigate the impact of external interference whenever it causes deviations in the displayed values.
● Comprehensive protection features, including a fuse-blown indication function.
