Hello,
I would like to get some secondary opinions on my power supply circuit that i have designed. I designed it with the idea that it will pass EMI certification and LV safety regualtions in mind. The supply will be used to power a control circuit for an electric car charger that is mounted in a public street lamp.
This will be routed on a 2-layer pcb that has about 2W of power draw and some sensitive electronics on board (GSM, PLC modules).
I added Some Kemet X1 and Y1 safety capacitors rated for 400V and also 3 varistors to protect against transients (combined with a GDT).
I added a 1A slow blow non-replaceble fuse on both lines, since i cant guarantee the device will be wired with line and neutral spacified.
I chose an integrated power supply unit thats galvanicly seperated and has built-in EMI filtering in it.
If there is anything here that i am missing or is maybe unnecesary let me know. All feedback is apprechiated.
