  • Description
  • Key Features
  • Technical Specifications

The DTSU666-HW 100A Smart Power Sensor is a three-phase, high-accuracy metering device designed for monitoring, energy management, and power export limitation in solar PV systems. It’s DIN-rail mountable, low power, and integrates via RS-485 (Modbus-RTU). Ideal for residential and commercial installations seeking precise real-time measurement of voltage, current, power, frequency, and energy metrics.

  • Rated up to 100 A three-phase current with included CTs (100 A / 40 mA). 

  • Supports both 3P3W and 3P4W wiring configurations. 

  • High measurement accuracy: ± 0.5% for voltage & current; ± 1% for power/energy. 

  • Very low internal power consumption (≤ 1 W) for efficient monitoring. 

  • Compact, robust construction: DIN35 rail mount, rugged casing, wide temperature range. 

  • RS-485 interface using Modbus-RTU for reliable communications with inverters or monitoring systems.
