Three-phase power meter U-PM

DIN rail

Multi-circuit Power Transducer (3.5mm DIN Rail / IP20)​ 1 & 4 Circuit Power Meter for Options Internal 2MB Flash Memory Capacity Standard RS-485 Modbus communication Isolation：AC 2KV, 50/60Hz, for 1min, Between Power / Input / Output / Case The U-PM series was designed for multi-circuit power measurement, up to 12 single phase or 4 three-phase circuit power input. Applicable to different types of power circuit makes U-PM a valuable option. Hardware standard built in a RS485 (Modbus) communication port, demand function, data logging and 2MB Flash memory. At the same time, din rail mounting provides easy installation and larger elasticity.
