Application:
Public
three-phase prepayment watt-hour meter is the new generation of
three-phase meters,
integrating prepayment processing unit with conventional three-phase
mechanical meter.
Data is transferred two-way between meters and vending management system
via IC card.
One
public meter is used by more than one user and accepts
multi
cards.
Each user prepays the electricity which he consumes from the public
meter. For
example,
Chinese farmers share one meter to irrigate their own farmlands by turns.
Applicable Standard:
