The power of household appliance is direct
proportion to that of mains voltage load, so the actual load
varies. The hi-frequency filter network and low-frequency filter
network are designed at the circuit respectively, can resist and
control the surge current and impulse voltage caused by frequently
starting the electrical appliances, so they are good for reaching
the best efficiency of saving electricity with respect to input
current/voltage, and the economizer has the good energy efficiency,
what"s more, in general, most electrical appliances are the
inductive loads. In addition, the wire of energy meter is leaded to
the family internal wiring part, as for 220V above, the economizer
will stabilize the voltage and reduce the current, as for 220V
below, it will add the use capacity of system device to reduce the
consumption of circuit and to prolong the service life of
electrical appliance, finally to get the aim of saving electricity.
Its min electricity saving ratio is up to 13%, and the max can
reach as high as 30%.
Household economizer equipped is helpful for
improving the power factor not destroy the household appliances,
and the reason of being equipped with Ban-Shen Power economizer is
that the phase of inductive circuit is 90 0 lag, the phase of
capacitive circuit is 90 0 advance, the power factor PF is equal to
COS θ , and the electricity supplied by electric power corporation
always passes the transformer or transformer box which is the
inductive set and the phase is 90 0 lag, in light of these, the
Ban-Shen Power economizer can be used to make the phase of the
whole circuit approach to 0 0 , because of COS θ =1, W=VA．Cosθ, the
nearer θ value gets to the 0 0 , the better use of power supply
will be. The whole circuit presents the actual work not the virtual
work, so the less virtual work you get, which means you waste the
less electricity offered by the electric power corporation, as a
result, you get the discount of electricity.
