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

"Connector to the bracket voltage" electronic ballasts. For supply of the at least one gas discharge lamp of high pressure sodium ballasts comprises an inverter and output circuits. An output circuit includes an output transformer is connected to the output and used to connect to one or a plurality of lamps. The secondary winding of the output transformer comprises a tap connection. The pressure limiting impedance coupled between the tap connections and between the ground. Determining the size of the tap position of the connection (240), and determines the pressure-limiting impedance, so that the ground and the output connections of any of the voltage between the one held in the regulation and / or safety under the requirements of the following applies.
