## Summary description

SHANGHAI BITUO HS083816 is a 3P+N energy monitor rated for up to 120A designed to measure electrical parameters in three-phase systems. It supports Modbus RS485 communication for integration with building management or monitoring systems. Suitable for industrial and commercial installations, it provides real-time monitoring of energy consumption and power quality for efficient load management.

## Long description

SHANGHAI BITUO HS083816 is a smart energy monitor for 3P+N systems (three-phase with neutral) with integrated Modbus RS485 communication. The device is mounted on a DIN rail and supplied with three split-core current transformers (CTs) with 16 mm aperture, enabling current measurement up to 120 A per phase. It measures voltage, current, active power, energy consumption and frequency in real time and can be applied in both three-phase and single-phase installations.
Advantages
The monitor provides accurate energy measurement with 1% accuracy (Class 1) and independent detection for each phase via three CT modules. Split-core CTs allow quick installation without interrupting the power supply. Modbus RTU (RS485) communication ensures stable integration with industrial control and building management systems. The unit is DIN-rail mountable, features a reset button, low own consumption (\<2 VA) and an extended operating temperature range (-25 °C to +70 °C).
Suitable for
Industrial three-phase distribution boards requiring per-phase monitoring
Commercial buildings and offices for energy tracking and management
Integration with SCADA or BMS systems via Modbus RS485
Retrofit installations where non-intrusive CTs are needed

How to use
Mount the HS083816 on a standard DIN rail inside the distribution board. Install the three supplied split-core CTs around the corresponding phase conductors and close the CTs to secure them. Connect the voltage inputs to phase and neutral according to the wiring diagram and wire the RS485 pair to a Modbus master device. Power the unit from the specified supply and use Modbus registers to read real-time voltage, current, power, energy and frequency values. Use the reset button to clear cumulative energy or status as required by your monitoring setup.
Usage recommendations
For accurate measurement, ensure CTs fit the conductors without overlapping and follow correct phase-to-CT wiring. Use a compatible Modbus RTU master and configure communication parameters (baud rate, parity, slave address) to integrate with existing BMS or SCADA systems. Observe the IP20 rating and install the device inside an electrical cabinet to protect against contact and dust.
