Datasheet

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.
 

Application 

  • Electric billing management for rental buildings/apartments 
  • Marketing food stalls and mobile homes billing management
  • School dormitory/exhibition booth electricity billing management
  • Store rental booth electricity management​
