| Single-phase electronic multi-rate watt-hour meter Appearance and installation size Type；DDSF8888 Product：LTCAF1 Weight：about 0.76kg ☆ Product Brief introduction Single-phase electronic multi-rate watt-hour
meter is one of the multi-rate watt-hour meter, which is according
to the Communicate Agreement of jiangshu & Zhejiang Province
and the correlative standard of the state. This product is adopted
advanced software designer, high capability hardware to design, and
the SMT production technology. It with advance technique, high
stability and high accuracy, The product with high stability, high
accuracy and easy operation, is an idea product for power
departments to carry out time-sharing electric charge All the
indexes comply with the standard of DL/T614-1997,GB/T17251-2002 and
GB/T 15284-1994.And the Communicate Agreement accord with
DL/T645-1997。 ☆ Function and features 1. Each of three periods has different
rates (peak period, smooth period and trough period). Every
period of time can be programmed into 12 periods of time and the
minimum time interval is five minutes； 2. All the consumption date can be reserved for
12 months； 3. It can auto. Identify the directional, will
be auto save and accumulate to the forward direction power counter.
It can auto. save the reverse direction power , starting time and
the total time； 4. It has the function of reverse directional
pulse test and indication； 5. It has the isolated RS485
communication, and design for prevent from the lightning
strike； 6. Date-copying adopt the password and program
switch protection, recording the latest program time and degree； 7. It adopt the hardware clock circuitry, low
current consume. The battery is one-time and environmental
protection lithium battery； 8. It can setup the meter number, bureau number,
time-period,、rate、 date、time、 meter reading time, password and the
initial electric power； 9. It can indicate the short voltage of the
battery, the hardware state of the meter, the communication state
of the meter, the clock state, the power directional,
time-adjusting state and the present time-period. It can read via
RS485 or hand computer； 10. The ammeter can be checking meter automatically
the sun changes the moon outage； ☆ Specification and Technical Date 1. Rated
