Automatic controller for voltage·surplus electricity without interruption of electric power

摘要

PURPOSE: A power saver is provided to be capable of stabilizing an output voltage although an input voltage of a power company is varied. CONSTITUTION: A main winding(L1) where a load current flows is provided at a cylindric winding core(K), and two excitation winding(l1,l2) where an excitation current flows are connected in serial. A plurality of relay contact points(a,b,c,d,e,f) for appropriate combining and coupling of the excitation windings are provided at an input side of a power. A low voltage relay(10) is configured to sense an input voltage and control the relay contact points. A condenser(C) is configured at an output side to improve a power factor of an electric load.
