Opis
The GMK330 is a three-phase smart meter designed to measure local electricity consumption and demand with high accuracy of Class 0.5. It comes equipped with three current transformers (CTs) rated 120A:40mA, enabling safe and effective measurement of higher currents in PV systems with large load consumptions.
The meter supports grid types 1P2W, 3P3W, and 3P4W, with an operating voltage range of 90–264 V (L-N for 3P4W, L-L for 3P3W) and dual frequency operation at 50/60 Hz. It communicates via RS485 over distances up to 1000 m and offers 50 ms high-speed refresh for faster control, making it suitable for charge control in hybrid inverters and zero-feed/export-limit applications.
Housed in a compact 4-module DIN-rail enclosure (72 × 85 × 72 mm, 240 g), the meter operates reliably in temperatures from −30 to +70 °C and altitudes up to 3000 m, with IP20 ingress protection and minimal power consumption below 5 W.
