Extended Flush Type Single Phase Electric Meter / Digital Electricity Meter
The DDSY168-E is a derived type from DDSY168 basic version. It is equiped with a extended transparent terminal cover, reserved with slot for MCB. This setup offers safe maintenance and meter inspection to avoid electric leakage and shock. The meter is a single phase two wire keypad based STS prepaid meter. It is used for low voltage residential and light commercial environments. With the dynamic range of 5(80)Amp current and 30Vm RF withstand immunity, the meter can operate in very severe environments.
The DDSY168-E is built in a compact BS footprint housing of polycarbonate fire retardant closure and intended for rich metering features. It can provide both consumers and utility users broad range of information such as V, A, PF, P, balance for them to budget their usage. It also supports tamper detection and SRE (significant reverse energy) measurement for active energy.
The meter is provided with a metal plate on the back. This design can tightly fix the meter body agaisnt the mounting surface to prevent tamper and sabtage, plus BS footprint mounting DDSY168 is an ideal for both new installation and retrofitting applications. A utility can generate the maximum income with the DDSY168-E with no need to purchase further protection accessories.
