The Multitek M100‑WA5 (also branded Hobut) is a DIN‑rail mounted active power transducer designed for measuring power in three-phase, four-wire, unbalanced systems. It accepts input from a current transformer (up to 5 A) and line voltage up to 600 V AC, then outputs a DC signal proportional to instantaneous power—ideal for monitoring energy usage, integration with PLCs or data systems, and power station or generator set monitoring.
