It measures active power on a direct-input 1P+N circuit at 230 V ±20 %, rated 63 A continuous. Class 1 accuracy for active energy per IEC 62053-21. The LCD display shows up to 999.99 MWh.
Rated 63 A continuous at 230 V AC — sized for direct metering of a single-phase residential or light commercial sub-feed. The 1P+N topology means it meters the line conductor only, with a neutral pass-through. Class 1 active energy accuracy (IEC 62053-21) keeps billing-grade error under ±1 % from 5 % to 100 % of rated current at unity power factor. The pulse output provides one dry-contact pulse per metered energy increment, configurable via the yellow activity LED for local indication. Output voltage is 24 V DC at 18 mA or 230 V AC at 100 mA, 200 ms impulse duration — compatible with most PLC digital inputs or remote totalizer counters.
