Detail
The UNI-T UT503PV is a high-performance insulation resistance tester built for both photovoltaic (live) and standard (non-live) applications. With test voltages up to 1000V and insulation resistance measurement up to 4000MΩ, it’s ideal for solar system diagnostics and electrical safety testing.
It supports both AC (5–600V) and DC (5–1000V) voltage auto-recognition, and features stepping voltage, auto discharge, IR comparison, time measurement, and high-voltage alarms for comprehensive analysis. For solar applications, it safely tests PV circuits up to 1000V DC with a low short-circuit current (<1.2mA), ensuring protection of sensitive components.
The device includes both USB cable and Bluetooth app support for easy data management (up to 1000 readings), and comes in a compact IP54-rated body with CE, UKCA, and cETLus certifications. Accessories include MC4 test leads, alligator clips, Type-C cable, and optional charging dock (UT-W13). Powered by 6 AA batteries.
