      Re: part id help

      cheers selldoor there my mates rope lights basically the lights consist of 10 meter white constant on led rope lights this bridge rectifier was enclosed in like a torpedo shape molded plastic block (had to cut it open to get inside ) then found this part and only this part so this has 240 volts in then it goes through the bridge converts to dc volts out? then goes to the rope light run. so could i run this of a adaptor like a old laptop one? how can i work out what the output of that rectifier is? and is it 3 amps.cheers vince

        Re: part id help

        No- if and only if that is the only component between the mains and the light string then it will be output 230 * 1.41 approx 325VDC.
        If size is not a restriction so others are available

          cheers for that i will enclose it in a project box or something i need to make a capacitor order up so will use the link for that as well cheers any idea how long the free postage handling offer is on for?

            I dont think it says but it has been running for a few weeks now.- best get in quick Its normally only free for over £45.
            Doesnt affect me as I live nearby.

                Wow thats the big one! 1000v.

                Anyway the picture and the diagram of the part on the datasheet shows the pin designation and it is probably on the part itself..
                Centre Pins are AC doesnt matter which is which and the DC + is at the end with the slope.

                  Re: part id help

                  cheers selldoor did not realize it was 1000 volts should still work ok ? as its only 240v ac in.
                  is the 1000 volts max voltage it will Handel? just got to figure out which is live and neutral on the actual rope light now somehow.

                    Re: part id help

                    Hi - Yes I think it will be ok -that is the max v.
                    I am guessing the bulbs are not leds and if they are tiny grain of rice bulbs
                    are they 150 bulbs at 1.5v so supply 225v would be good.

                    If that is the case and they are 1.5v filament bulbs I dont think it will matter
                    which is live and which is negative, BUT I dont KNOW for certain.

                      203 white leds about 2 or 3 mm each led so do you think this will work? like this they dont flash or any thing just plug in turn on.

                        Obviously it should work - you have just changed the bridge. BUT if they are leds then I think it does matter which is pos and neg. So you need to wait until someone who knows
                        chimes in. Did the bridge you took out have any markings - did you take a pic of it in situ.

                          no it was broke in bits after removing it it was in like a torpedo of molded plastic ie have mains plug then wire then this torpedo molding with the small bridge rectifier part number HY RU 3KBP10 molded in side then a length of wire onto the rope light on the out side of the torpedo molding plug end stamped ac rope light end stamped dc if makes sence.

                            Please post the pictures. White LED has forward voltage between 3~3.6V so the configuration of your LED rope must be LED strings connected in parallel.

                              bud will try posting pics but they are sealed in like a clear/glitter hosepipe so i dont think a pic will pick up each led i have just looked really closely yes they are in parallel and every ninth on has a resistor.

                                If you can count the quantity of the LED on each string, then you can figure out how much voltage it will need to forward bias all the LED in the string + the current limiter resistor.

                                  Hi all, a newby question about a bridge rectifier I'm trying to identify.

                                  I'm in the midst of reparing a battery charger in work which went pop, The bridge rectifier has shorted and took out a couple of other components. The rectifier in question has a part number KPB305G, and it looks like it's obsolete. Does any one know what I could replace it with?...

                                  by mpn78
                                  Hello

                                  My Fujitsu Esprimo Q556 motherboards blew up. At least fuse, bridge rectifier and capacitor got damaged. I have changed fuse and bridge rectifier (DF1508S), but I don't know what capacitor it is (picture). I know that capacitors size is 47nF, but I don't know other specs for it. Can you help me to choose right capacitor for my motherboard?
                                  There is 240V AC on input side of bridge rectifier and 340V DC as output on capasitors side.

                                  Thanks....

                                  I'm trying to help my friend who owns a restaurant be just bought.
                                  He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
                                  It's stuck using, I guess, the 2 sided tape that comes with the strip
                                  The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth...

                                  So My iPad was not charging and booting up . i went to a local technician and he checked with thermal and this Part marked in 1st Photo is Short.
                                  So then i went on to boardview and downloaded the schematics and identified this part in 2nd Photo. Now i am confused what exactly is the part called ? where should i get this from ?


                                  i contacted my technician and he sent me his BoardVIew screenshot in 3rd Photo. In his Boardview the part is called X2826.... Something

                                  SO My main concern is what part should i order what should i search the name for ?

                                  When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier...
