The CHINT DTSU666 is a three-phase smart energy meter (DIN rail) suitable for 3×230/400V networks with direct connection of 5(80)A and 4 poles (4P). It is ideal for photovoltaic applications, self-consumption, and energy monitoring in residential or commercial spaces.

• Supports bidirectional measurement (import/export).
• Records and displays key electrical parameters such as voltage, current, active/reactive/apparent power (kW/kVAr/kVA), frequency (Hz), and power factor (PF).
• Measures energy (kWh/kVArh).
• Features an LCD display with backlight.
• Capable of RS485 communication with Modbus-RTU protocol.
• Easy integration with inverter, data logger, BMS/EMS, or telemetry systems.

Able to accurately control consumption and monitor energy flow in installations where reliable measurement and remote reading are required.
