Description

The UNI-T UT503PV PV Insulation Tester is designed to measure insulation resistance in photovoltaic (PV) systems and conventional electrical equipment. It supports live PV insulation testing up to 1000V DC and standard insulation resistance testing at 125V, 250V, 500V, and 1000V. With AC/DC voltage measurement, automatic discharge, stepped-voltage testing, and data storage, it helps solar technicians assess insulation performance during installation, commissioning, and maintenance.

WHAT IS THIS PRODUCT USED FOR?

The UNI-T UT503PV is used to test insulation resistance in solar PV strings and conventional electrical installations. Its dedicated PV mode supports testing of energized photovoltaic circuits within the instrument’s specified limits, while its standard insulation mode checks suitable de-energized electrical equipment.
