Switching Power Supply Mains voltage is inserted via filtered IEC CN3. Earth is connected directly to chassis from the body of CN3. Live passes through fuse F2. Live and Neutral pass though a further filter consisting of C2 (X2 rated), L1 - a common mode choke - and C15 & 14 (Y2 rated). Live passes through the soft-start system, TH1, R14 and RLY1. R14 limits the initial current surge caused by the primary reservoir capacitors charging up. TH1 protects R14 if a fault causes excessive dissipation in R14. RLY1 shorts out TH1 and R14 when the PSU is running. Live and Neutral then pass to bridge rectifier BR2 which, for the 230V setting full-wave rectifies mains, smoothing performed by reservoir capacitors C22,23,44,45,32,33. In the 115V setting, this power supply is configured as a voltage doubler. Thus, the High Tension (+HT) DC gen
