The TBC Single Phase DIN Rail Energy Meter is designed for accurate measurement of electrical energy consumption in residential, commercial, and light industrial applications. Featuring a compact modular design, LCD display, and pulse output, it ensures stable, precise, and long-term monitoring of power usage with Class 1 accuracy and reliable data retention even after power failure.
The TBC8825S Single Phase Energy Meter provides an efficient and cost-effective solution for monitoring electrical energy consumption in various applications. Built with advanced digital conversion technology, this meter delivers Class 1 accuracy for reliable billing and energy management.
Its compact DIN rail design allows seamless integration into standard distribution boards, making it ideal for sub-metering in residential complexes, commercial buildings, rental units, and solar energy systems. The 5+1 digit LCD display provides clear, easy-to-read consumption data, while the pulse output enables connection to building management systems or remote monitoring equipment.
Engineered for long-term reliability, the meter features data retention capability that preserves consumption records even during power outages. With low power consumption of just 2W and robust construction suitable for operation in temperatures from -20°C to +55°C, the TBC8825S delivers consistent performance in diverse environmental conditions.
The meter operates by sampling energy consumption through voltage divider and current shunt signals. These signals are processed through precision amplification and digital conversion circuits, then displayed via the LCD screen. Simultaneously, the meter generates pulse output signals proportional to energy consumption (1600 impulses per kWh) for integration with external monitoring and control systems.
The TBC8825S is designed to meet Class 1 accuracy standards, ensuring measurement precision within ±1% for reliable billing and energy management. The meter operates on standard 220/230V AC supply at 50/60Hz frequency, with a rated current of 5A and maximum current capacity of 60A for direct connection.
Power consumption is minimized at ≤2W active power and ≤5VA apparent power, ensuring the meter itself contributes negligibly to overall energy usage. The pulse output provides 1600 impulses per kilowatt-hour, offering high-resolution data for external monitoring systems.
