Three-phase Electronic Prepayment Energy Meter
Detailed Product Description
The DTSY256 Three-phase Electronic Prepayment Energy Meter's specifications:
Function and Features:
(1). Use the measuring chip specially for three-phase, which can measure accurately the active power in the three-phase grid.
(2). Realize the function of prepayment and use the electricity afterwards.
(3) Alarm function: when the left electric quantity is less than the set quantity, it can remind the user to buy the electricy in time.
(4) Electricity use control: When the left usable electricity is zero, it can automatically switch out. When the user buys the electricity and insert the card, it can return to supply the electricity.
(5) The power administration needs to install the card-writing machine and the electricity sale management system. The user-bourgt electric quantity can be recorded in the power card with password. The user can insert the card in the energy meter to transfer the bought electricy to the energy meter.
(6). It can be set as one card per meter and several cards per meter
