The TBC8825T Three Phase Energy Meter represents a professional-grade solution for energy measurement and monitoring in three-phase electrical systems. Designed specifically for commercial and industrial applications, this meter combines precision measurement technology with practical features that simplify installation and operation.

Built to handle rated currents of 3 × 10(100)A with direct connection, the meter eliminates complexity while maintaining accuracy. The integrated LCD display provides instant visibility of energy consumption, while the pulse output feature enables seamless integration with building management systems and energy monitoring platforms.

The optional RS485 communication interface with MODBUS-RTU protocol allows for remote data collection and integration into SCADA systems, making it ideal for facilities requiring centralized energy management. Data retention capability ensures that critical consumption information is preserved even during power interruptions.

Engineered for reliability and longevity, the TBC8825T operates efficiently across a wide temperature range and features robust construction suitable for industrial environments. DIN rail mounting ensures quick, secure installation in standard electrical enclosures.

Measurement Technology: The TBC8825T employs advanced digital sampling technology to measure voltage and current in three-phase four-wire systems. Voltage and current signals are simultaneously sampled through precision sensing circuits, then processed through high-resolution analog-to-digital converters.

Signal Processing: The digital signal processor calculates active energy consumption with Class 1 accuracy, ensuring measurement errors remain within ±1% under rated conditions. The meter continuously monitors all three phases independently while calculating total energy consumption.

Display and Output: Energy data is presented on a high-contrast LCD display, showing cumulative kWh consumption. The pulse output generates 400 impulses per kilowatt-hour, providing a standardized signal for external monitoring equipment, data loggers, or building automation systems.

Communication Protocol: When equipped with the optional RS485 interface, the meter supports MODBUS-RTU protocol, enabling remote reading of energy data, instantaneous power, voltage, current, and other electrical parameters. This facilitates integration with energy management software and SCADA systems.

Data Integrity: Non-volatile memory ensures that accumulated energy data is retained during power outages, maintaining accurate long-term consumption records without the need for battery backup.

Installation Requirements: The meter requires standard three-phase four-wire connection (3 × 220/380V, 50Hz). DIN rail mounting allows installation in distribution boards with minimal space requirements. Proper sizing of upstream protection devices and wiring according to the 100A maximum current rating is essential.
