Product Details

Specifications

It can measure active power which the frequency is 50Hz or 60 Hz.The electric card can realize bidirectional data transmission.

Product overview:

DDSY single phase electronic prepayment watt-hour meter uses advanced specific integrated circuits. It uses full automatic surface mounted technology (SMT). The design of circuit and the selection of components are in accordance with the biggest environmental tolerance. It can guarantee long-term and stable operation. It has high precision, high overload, low power consumption and high reliability. It can realize on and off of load and urge the user to use electricity after purchasing through control relays.

Features of function:

It can be applied to computer management, first purchase electricity then consume electricity. Limit the maximum power within rated current range (defined by the electricity sector). Each meter has a card. The card is specialized. You can still use electricity if you lose the card, and you can fill the card to continue to use. The electric card can realize bidirectional data transmission. It can switch off automatically when the electricity is zero. It has anti-theft software design. It can measure active power which the frequency is 50Hz or 60 Hz.It can be installed indoors. The applicable environmental temperature is -20~+55°C , the relative humidity can not be over 85%. There is no corrosive gas in the air. Avoid dust, salt spray, gel, etc.
