DTSU666‑H

The DTSU666‑H is a three-phase smart power sensor, primarily designed for photovoltaic system applications where monitoring and control of power, energy, voltage, current, and other electrical parameters is required.

Some key features and uses:

• Measures, in real time, the values of all three phases: voltage, current, active/reactive power, frequency, and energy (import/export)

• Built-in LCD display for instant on-site reading of values

• Communicates via RS‑485 using the Modbus‑RTU protocol, allowing it to interface with an inverter or an energy monitoring/management system

• Low power consumption, so its operation doesn’t significantly affect the overall system load

• DIN rail (DIN35 mm) installation for easy mounting inside electrical panels

It is particularly useful in cases where the inverter needs to know the actual consumption and production in order to properly manage energy flow—for example, in self-consumption systems or for controlling grid import/export.

*The product is supplied as an independent unit, with the option to be combined with accessories according to the needs and design of the installation.
