China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Sodium lamp ignitor from the positive terminal of the voltage through the transformer primary winding, all the way through the secondary winding of the transformer, respectively, to the negative terminal of the capacitor through a phase, the charging capacitor to the diode anode, all the way through the SCR, diode and resistor to the negative side, all the way bypass capacitor through a resistor and were treated with diodes, resistors to the negative terminal and through SCR ignitors diode to the control electrode. Characterized in that the trigger circuit is positive or negative terminal of the series with a bimetallic temperature relay. AC voltage is not less than 180V, power 35-400W sodium lamp starts.
