1. [Amps] PSUD/ R b4 caps / step start / 6A10 diodes. (score: 1): Author: "Jim Thomson" <Jim.thom@telus.net>; Date: Fri, 12 Feb 2010 06:56:58 -0800; I just looked at PSUD with a 25 ohm transformer, 2500 VAC and 25uf with 8 ohm esr filter cap. No resistor before filter. The surge current on the first half cycle is around 26 amps. Then peak current; /archives//html/Amps/2010-02/msg00343.html (9,702 bytes)
