Application:
DTS951 series electronic single-phase
electric meter is the most advanced static
electronic meter in china.The meter designs
use large-scale intergated circuit.High reliability
step motor,it can the Ac single-phase active
energv (voltage rating:220v:frequency 50Hz),positive
and negative two directions and accumulates
in one direction.The test singnal is isolated
by phototransistor:it also has the function
of anti-fraud,and indicates it's operation
situation on flash light,so it could be managed
very easy.
The quality technical norm of the products
is in accoordabce with the GB/T17215-1998
national standard and IEC521-94 international
standard.

Principle：
The
meter samples the voltage and the cuttent
at the voltage divider and the current divider
built in the meter.these samples are sent
to the amplifier and multiplier,output of
the multiplier is processed by the integrated
cicuit.V/F conversion,frequency divider,power
dive circuits to provide plus to drive step
motor and mechanical register to accmulate
customer electrical energy consume. |
Key
speciflcation：
High accuracy:error＜±1.0％2.0％class High
sensitively:initial staring current＜0.4％ib Range
of large load:currentr overload ratio＞6 Low
power consumption:consumption of meter itself＜1w
Ambient temperature:-20℃～ +45℃ Hing reliability:MTBF＞10×10 Weight:＜0.6kg
Starting current the meter can work corectly
at rated voltage,rated frequency.
When load currdnt is large then 0.4％Ib.(Power
facotor:1).Running with no-load The meter
use logic circuit to anti-creep |
