Products Application

Magnetic ballast for MH lamp or HPS lamp, designed to reduce or limit the current in an alternating circuit. The main purpose of an inductance ballast is to regulate the power supply of a circuit. It can also provide the necessary impedance and voltage in the circuit to make it work correctly. Additionally, it can also be used to limit the voltage and current in a lighting circuit.
