Capacitive fluorescent ballasts:Including resistors, capacitors, diodes and relays, 220 VAC input termination, then and then after a resistor and a capacitor in series a diode across the relay normally closed contact with the current zero line and relay the input of the phase, out of the relay terminal and the diode other end connected to fluorescent lamps. The utility model has a few parts of the circuit constituting more than 30% energy saving, high power factor, to facilitate the work, you can work at low voltage, high reliability, long lamp life, good benefits, etc..
