HT INSTRUMENTS PV-CHECKS ONEPLUS aurinkosähköasennusten testeri (1011580)

With a maximum open circuit voltage of 1000V DC and short circuit current up to 15A, the HT INSTRUMENTS PV-CHECKS ONEPLUS is a dedicated photovoltaic installation tester compliant with IEC/EN62446 and VDE 0100/0105. It performs essential safety and performance checks on PV systems, including insulation resistance, continuity of protective conductors, and polarity verification.

Overview

The PV-CHECKS ONEPLUS is designed for commissioning and periodic testing of photovoltaic installations. It measures open circuit voltage (Voc), short circuit current (Isc), insulation resistance (Riso), and continuity of protective conductors (Rpe). The instrument supports insulation test voltages of 250V, 500V, and 1000V DC, with a resistance range from 0.01 MΩ to 200 MΩ. Continuity testing uses a 200mA current and covers 0.01 Ω to 99.9 Ω.
