Design of Power Supply for Mining Belt Conveyor Integrated Protection Device KHP178k-z Based on Topswitch-JX

Mining belt conveyor integrated protection device KHP178k-z is an important device for the supervision and protection of the belt conveyors. A new power supply based on TOPSwitch-JX is designed in this paper to ensure the reliable operation of the device. Applying TOPSwitch-JX, the circuit of the power supply is simplified and the output quality is improved. Experiments show that the output waveform is stable and the ripple is small. The power supply designed is effective to meet the requirements of mining belt conveyor integrated protection device KHP178k-z.
