Q: Hi , what is the DC voltage input for this product?

Asked by Pablosj on 2020-05-13 08:47:42

Nikolaj Dombrow as this is a SMPS you can also feed in the equivalent DC voltage, which would be approx. 325V DC for 230V AC, reason is that AC volts is given as RMS value, the peak value of a 230V sinewave is about 325V
