Benefits of the IR5050 and IR5051 Insulation Resistance Meters
- Maximum 5 kV test voltage - up to 10 TΩ of insulation resistance testing.
- IR5051: Measure solar PV system insulation resistance while generating.
- Handheld instrument with high-safety design.
HIOKI IR505x High Voltage Insulation Tester
The HIOKI IT5050 and IR5051 are compact, lightweight, high-voltage insulation resistance testers capable of outputting up to 5 kV. Their 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.
- Measure insulation of high-voltage equipment (such as transformers, cables, and motors).
- IR5051: In addition to a normal insulation resistance measurement mode, the IR5051 also features a specialized mode for measuring PV insulation resistance - 2000 V solar power system compatible.
- Complies with IEC 62446-1 for Category 1 and Category 2 tests, ensuring robust safety and performance.
- Wide testing voltage range, up to 5000 V from 250 VDC.
- Wide measurement insulation range, up to 10 TΩ.
- Automatically calculated and displayed insulation diagnostics (PI, DAR, and DD).
- Data memory functions increase your work efficiency by eliminating human errors from manual reporting.
- Optional USB and wireless connectivity (USB communication package DT4900-01 or Z3210 wireless adaptor required).
- Compact and lightweight, equipped with an IP65-rated carrying case.
- High-safety design.
