| Summary
of electric energy meter:
DDSY951 electronic single-phase
advace-payment electric energy meter(following
as meter) with a shielded and sealed construction,adops
microelectromic technoligy to measure electricity
and comes up to standard of GB/T17215-1998
and GB/T18460-2001.It collects handles and
stores dataset with advanced monolithic
processing system.The meter features in
good abti-electromagnetism,low power loss,high
precision,abstraction-of-electricity prevention,high
overload and long service life.
With computerized management,users purchase
electricity first and then consume it;maximum
power can be limited in rated current(limited
by Power Supply Department);one meter is
specially provided with one IC-card.Electricity
will not be cut off if the provided card
loses.A make-up IC-card will work as well;IC-card
can transfer dataset bi-directionally and
cut off electric current automatically,warning
user of purchasing power;when quantity of
electricity turms to zero,it can switch
off electicity automatically;it's supplied
with power-stealing prevention software.

The
meter uses large-scale integrated circuit(LSIC),SMT
technology and digital circuit.Key components
are selected form international brands,greatly
improving rliability and service life.
With elegant appearace,durable construction,the
meter is well sealed and shielded by fire-retardant
material ABS. |

Current：
On the condition that reference voltage,reference
frequency and COS=1.0 and that load current
equals to 0.004lb(grade1)、0.005lb(grade2).
3.Latent movement：
On the condition that volotage loop pluses
115 percent of rated voltage and that there's
no current,in circuit,otput that meters test
should not be more than one pulse.
4.Power loss:≤2W 10VA |
