Single Phase Energy Meter Type DDSF999
Single phase multi-tariff energy meter type DDSF999 is used to measure 50 Hz or 60Hz active energy and power flow of peak, shoulder, flat and valey time.All of its functions comply with the relative technical requirements for class 1 single phase whatt hour meter in IEC 61036-2000 and it's data communication rules obey the requirements of IEC 1107.
It is a new and high-tech adopting special large-scale IC, latest micro electronic technology and SMT production crafts.
It is designed for rough working condition and components selection as foundation. This all leads to a long-term stable operation.
