Overview

The SUCH active power transducer measures active power in 3-phase 3-wire and 3-phase 4-wire AC systems and converts the measurement into standardized voltage, current, or RS485 signals for monitoring and control. It supports AC voltage inputs from 57.7V to 600V and current inputs of 1A, 5A, 10A, or 20A, with an accuracy class of 0.2 or 0.5 and a response time of ≤400ms. It is suitable for switchgear panels, power distribution systems, SCADA monitoring, and industrial energy management applications.

Note: This power transducer measures active power in 3-phase 3-wire or 3-phase 4-wire AC systems.

Feature

3-phase 3-wire / 3-phase 4-wire measurement — supports common three-phase wiring configurations for flexible integration into AC power systems.
AC input 57.7–600V voltage, 1A/5A/10A/20A current — accommodates different three-phase system ratings with configurable input options.
0.2 or 0.5 accuracy class — provides precise active power data for power monitoring, metering, and load analysis.
Response time ≤400ms — responds quickly to changes in measured power for continuous monitoring and control.
0–10V, 0–5V, 1–5V, 0–1mA, 0–10mA, 0–20mA, 4–20mA, or RS485 output — connects measured power data directly to PLCs, DCS, SCADA systems, meters, and data acquisition equipment.
Input, output, and power supply isolation — separates measurement and control circuits to reduce signal interference and improve system reliability.
ABS fireproof enclosure, AC 2kV dielectric strength — provides enclosure protection and dielectric withstand for installation in electrical control panels.
DC 12/24V, AC/DC 110/220V, or 2-wire loop power — accommodates different auxiliary power configurations used in industrial control systems.

Pretty happy with this active power transducer

I replaced an older power transducer in one of our control cabinets and used the existing CTs. I spent some time checking the CT direction and phase wiring before connecting the new unit. The first readings looked right, so I left it running and checked it again later under a different load. Everything has stayed pretty consistent.
