Three Phase Prepaid Energy Meter

 

Right now Acrel has three prepaid energy meters, ADL100-EY single phase prepaid meters with intro-control, ADL300-EY three-phase prepaid meters with intro-control, and ADF400L prepaid energy meters, they are widely used for calculating the single and three-phase active energy respectively on the frequency of 50 Hz. The meter has functions of prepaid, load controlling and RS485 communication, etc. Inside meters have a small holding break to realize the current on or off. With the Acrel IoT EMS platform can realize remote control the power. These meters meet the related technical requirements of electronic power meters in the IEC62053-21, IEC62053-22 standards.
