Three Phase Four Wires STS Prepaid Meters 3P KWH Meter Keypad Prepayment LCD Display
Build-in with up to 16kV / 8kA surge protection VDR,the DDSY168 is a one phase two wire meter designed for unique African and South American environment prone to lightening or other line surges. It is finished in a compact BS footprint mounting enclosure of flame retardant polycarbnonate , with 30Vm withstand of RF immunity, allowing to be installed in very harsh environment. The meter is widely used for residential and light commercial , tenant submetering scenarios.
The DTSK150 combines IEC compliant accuracy metrology and DLMS/COSEM standard compatible communication technology. The meter adopts power line carrier of BPSK FSK narrow band PLC communication for data exchange and automated meter reading. It offers utility users and service providers a sound data collection and revenue protection tool and a real-time monitoring system.
