Din-Rail Single Phase Split Meter
DIN-Rail series are residential split type prepaid electricity meters, with conventional and smart options. They can be configured in Prepaid or Postpaid mode and provide utilities with a high degree of accuracy and reliability, allowing for single-phase connection.
These DIN-Rail meters are designed based on 20-bit Token in accordance with STS specifications, fully complying with DLMS/COSEM IEC standards and certified with DLMS, STS, SABS certificates, and the compact construction design makes it possible to install them in a cluster box with various capacities of 1, 2,5,10, etc. meters. Their robust anti-tampering and prepayment functions make them ideal low-cost devices for revenue collection and protection solutions.
