RF Communication Keypad Prepaid Single Phase Watt-hour Meter
DDSY168
Single Phase Prepayment Keypad Electricity Meter
The DDSY168 is a single phase two wire STS compliant prepaid electricity meter finished in a compact, keypad-based BS5685 footprint housing. It miantains the rugged RF immunity withstand of 30V/m and IP54 rating, up to 13KV surge & lightnening protection, and down to 80V operatable voltage, allow it to be installed in very harsh and voltage-tip frequent environment, like Africa and central America continents. The meter is used by residential, light commercial and industrial environments for submetering and tenants metering applications.
