If a trolley has a 120VDC power supply intended to power auxiliary components such as lights, buzzers, and speakers, how would the speakers connect to that power system? I understand that speakers typically operate on AC, so what is the most efficient way to connect them to the 120VDC setup? Additionally, could you provide an estimate of the power output for the speakers?

When I reached out to the manufacturer, they asked for the total power consumption the converter would need to handle.To estimate this, I calculated the power requirements for the components that will use the 120 VDC supply: interior lighting, end lights, and buzzers. The breakdown is as follows:- Light Bulbs: 16 bulbs at 10 W each = 160 W- Buzzers: 2 buzzers at 5 W each = 10 W- End Lights: 2 lights at 15 W each = 30 W This results in a total estimated power demand of 200 W.My concern is whether I should request a higher wattage rating for the converter to provide sufficient tolerance and ensure the system operates efficiently without risking an overload. Note: The DC power system is designed specifically for a trolleyarrow_forward
