Nobody ACTUALLY changed their voltage, at least initially. In Sweden we did change from 220V to 230V a long time ago. Yes I could measure that on my volt meter. 230.5V on all 3 phases and 400V between the phases 5 minutes ago. You have 3 phase domestic power supplies in Sweden? You can have it in Australia if you ask for it... Is there any point? Can you actually buy any domestic apps which use three phase? Ducted domestic air conditioning systems often require 3-phase power. - Franc Zabkar -- Please remove one 's' from my address when replying by email. |

larrymoencurly wrote: These bleeders are needed to equalize the voltage between the input capacitors, Inside my Enermax EV365P-VD.. I couldn't find any bleeder resistors across the high voltage 680uF capacitors or even empty spaces I still don't understand why there were no bleeders because I've seen them in even the cheapest PSUs Should I solder an approx. 200K resistor across each of those capacitors in the Enermax? They are only needed for voltage equalization when capacitors are mounted in series. In the primary circuit this would be connected with switching from 115 to 230 v nominal input. If they are used in a voltage doubler circuit, for 115, no equalization would be needed. If they are put in series, for 230, equalization is required. This is what I don't understand because while I'm using 115VAC, this Enermax PSU has a switch for 230VAC operation. I know that when PSUs are shipped to countries where 230VAC is used, the line fuse is cut to half the amperage, but are bleeder resistors added for those countries? In the case of this Enermax there aren't any places on the circuit board for them. |
