Engineering Standards & Application Capabilities

Zhejiang TMB Electric Co., Ltd. produces DIN-rail kilowatt-hour meters engineered in compliance with international metering standards (IEC 62052-11 and IEC 62053-21). Designed for modular 35mm DIN-rail mounting inside standard consumer units and power distribution panels, our energy meters deliver high dynamic measurement accuracy across commercial tenant billing, rooftop solar net-metering, and factory automation sub-systems.

Each unit incorporates flame-retardant PC/ABS housing materials, high-contrast backlit LCD digital indicators, pulse outputs for energy management system integration, and optional isolated RS-485 Modbus serial communication channels for centralized SCADA or BMS connection.

Bi-Directional Net Metering

Accurate monitoring of both import and export active power flow, essential for grid-tied solar photovoltaic installations and battery storage systems.

IoT Cloud Connectivity

Integrated Tuya WiFi and Zigbee protocols allow wireless remote reading, real-time demand tracking, and scheduled load shedding directly via mobile apps.

Split Core CT Adaptability

Retrofit existing distribution boards effortlessly without breaking line cables using precision split-core current transformers rated up to 1000A.
