Hello Gene, R,S and T are just the traditional names of the incoming 3-phase mains supply, very common over here, but out of date. They were replaced by L1, L2, L3. This comes from the usual motor or transformer hookup. U,V, W were the motor (or transf.) leads while X,Y,Z were the ends of the rotor windings (in case of brushed rotor for soft start and power control) or transf. secondary.
It does not matter how you get those big capacitors charged, from two or three phases or from a 500 V DC net as some big machine shops provide. Just connect your mains and measure the resulting DC voltage. The following switching supply will never know where the DC voltage comes from, unless it's to low or has too much ripple, maybe.

So we'll see what happens in the next week. --- Diese E-Mail wurde von Avast Antivirus-Software auf Viren geprüft. http://www.avast.com ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
