Description

The IR5051 is a compact, lightweight, high-voltage insulation resistance tester capable of outputting up to 5 kV. Its unique measurement technology enables stable measurements of up to 10 TΩ. In addition, the IR5051 is capable of testing the insulation resistance of solar PV systems during power generation, and has a CAT III 2000 V safety rating to allow testing of 2000 V PV systems.

Dedicated Measurement Function
In addition to a normal insulation resistance measurement mode, the IR5051 also features a specialized mode for measuring PV insulation resistance.

Flexible Voltage Range
Effectively measures 1500 V solar PV systems and is prepared to accommodate systems up to 2000 V as technology advances.

Standards Compliance

Complies with IEC 62446-1 for Category 1 and Category 2 tests, ensuring robust safety and performance
