I've bought some cheap AC-DC converter online. The goal is to place it inside a roof lamp's base, and power an ESP8266 clone at 3,3 volts from mains (in Europe, so 220v/50Hz). The lamp connection (mains AC) runs through the roof and walls to the mains , and I can't know the length. I don't know the material or section either, nor if it's braided or solid.
So. The final goal is to power an ESP8266 which would activate either a relay or a dimming circuit. Of course, the same wires would be used to power the light through the relay or dimmer.
On the AC-DC converter, the places to connect N and L lines from mains seem quite small. And so I was wondering what section of wire I could use from the AC to the AC-DC converter, so it'd be a few centimeters (or inches).
The specifications for the AC-DC converter are the following:
- Input current:0.065 (AC110V) -0.032 (AC220V) A (at full load conditions)
- Input surge current:20A (full load)
- Input voltage:AC 85-265v 50/60HZ (at full load conditions)
- Output voltage:DC3.3V (±0.2V)
- Output current:1A
- Output efficiency:85% (rated load)
- Output ripple:50Mv
- Ambient temperature:-20 to 60 Centgrade
- Relative humidity:40 to 90% RH
- Switch overshoot:150%
- Output rise time:100MS
