Specifically designed for rail transit environments,this power supply is dedicated to passenger compartment lighting fixtures.Featuring a 3U chassis,it can be directly installed in standard cabinets.One centralized power supply is configured per passenger compartment,responsible for power supply and dimming control of the compartment's lighting fixtures.Internally,it integrates 4 power supply unit modules,an MCU mainboard with a 3.5-inch display screen,an input board, and an output board.Each output group of the power supply modules adopts redundant hot standby;each module is equipped with overvoltage and undervoltage detection and protection,output PWM(Pulse-Width Modulation) dimming,sensor head adaptive dimming,input emergency function,and fault output alarm.
