OEM No/Model: DDSY866
APPLICATION
Prepayment meter also called quantitative meter, IC card prepaid meter, in
addition the ordinary energy meter measurement functions, especially the
user need to buy electricity FIRST, USE second, after run out of power if the
user does not continue to buy electricity.the meter will automatically cut off, this
meter is best way to solve payment collection problem, it also has function of
anti tampering, overload protection, management of energy consumption
and user information.It is used to measure 50Hzor 60Hz active energy
consumption from singlephase AC Electricity net and adopts LSI (Large-scale Integration) and SMT manufacturing technique,the key components
and Part all adopts long life type.This type of meter is widely used in office
building, shopping mall, residential, and public facility etc.
FUNCTIONS AND FEATURES
-Meter base in made by ABS anti-flaming, with transparent PC window,
Meter terminal block is high temperature resistance material which is also
moisture-resistant, fire-retardant.
-Highly reliable special design for IC card entrance, which can bearing 'attack 'of 4kV static electricity shock.
-LCD 6+2 digits display, satisfy user demand, maximum 999999.99 kWh.
-One meter has one card, repeatable top-up, Effectively reduce waste.
-Once the prepaid meter available energy is reached zero, meter relay will
automatically cut the power off, unless the station has set overdraw limit ( Credit ).
-The meter can set alarming kWh quantity, indicated by LED flash and
secondary notice user the energy is staying Low, its in order to remind user to
recharge power on time, Avoid unnecessary loss.
-Load control, over-load automatically switch off, protect product been
damaged.
-Data-copying function makes the electricity department easily to manage,
data can be preserved for more than 10 years without power supply.
-Large-capacity magnetic latching relay control, measure energy in security
mode.
-Single direction measures single phase two wire active power c
onsumption, comply with international standard IEC62053-21,IEC62052-11.
-Directly connect operation maximum 100A or through CT
-Electricity price settable, easy to manage and adjustment.
-The meter has RS485 communication module, it's convenient to meter-reading.
