If your still concerned about inrush current you can put a soft start module between the source and LED driver. A proper soft start doesn't limit the voltage but slows the current until the capacitors charge then a relay closes the circuit for direct power from the source . NettetViewed 2k times. 1. I'm tring to choose a relay for my circuit which has a Filament LED bulb as load. The bulb is 230VAC / 60W 6W. The nominal current should be about 0.03A which is not an issue for a regular relay. The inrush current can go from 10 to 15 times that value, from what I understand. So it can go up to 3A 0.4A. people die after they retire

Maybe you are in the following situation right now: You have installed the new LED lighting and want to switch it on for the first time. After flipping on the light switch, the fuse will be triggered immediately. The new lamps remain dark. If the inrush current is too high, this can cause the fuse to trip, especially in … Se mer The inrush current is the electrical current that flows immediately after the lamp is switched on. With old incandescent bulbs, the inrush current is generated by the cold filament and can reach up to 15 times of the normal power … Se mer A high inrush current is not untypical due to the capacitive behavior of LED lights. In most applications, this inrush current is not a problem. Difficulties usually arise when a large number of light sources are operated on one circuit. This can … Se mer The inrush current of LED lights often becomes a problem when several lamps are operated in parallel. Fuses trip regularly or switch … Se mer If the problems listed above occur, the inrush current of the LED lighting is definitely too high. In this case the inrush current should be limited in a technical way.
