    SIT Controls BIC-320 SMPS schematics requested

    Hi All,

    I own a Dutch Remeha Central Heating unit which has a switched mode power supply designed by a company called SIT Controls BV. The type number of the smps is BIC-320 and the design is created with the use of a TOP245YN.

    I was just wondering if there is anybody walking around here who has the schematics of this power supply unit.

    Regards
    Henk

      If you cannot find the schematic, you can use the application circuit in the spec sheet of the TOP245 as a guide for troubleshooting.
      What is it not doing?
      Providing good clear straight shots of the whole top and bottom side of the board will also help.

          Onkyo DX-V500 Laser Disc Player - weird SMPS fault
          by dkneyle
          This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.

          Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...

          Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
          by shamsudeen
          Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
          I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

          i know that in linear power supply the noise will be very low comparing to SMPS supply....

          Omega MML200 Coutant Lambda PSU repair
          by Crystaleyes
          Hi all.

          Recently I picked up a vintage HP 37717B communications analyzer which uses one of these MML200 Coutant power supplies. Needless to say the PSU is not working, and surprisingly there is apparently nothing available on the web regarding repairing one of these. No stories, no schematics, zilch!
          There are however many companies offering repair 'services', however I don't have the luxury of sending it off, so am intending to do the repair myself.

          I admit right now that I am no expert on smps repair, although I do have a grasp on the principle of the general...

          Asus Nexus 7 2012 (ME370T REV 2.4) Schematics needed
          by Popalwali
          Hello Everyone,

          I will be really grateful if someone shares schematics and if possible the boardview of the old Asus Nexus 7 (2012) Tablet. The motherboard is ME370T Rev. 2.4. Now I can find schematics for the Rev. 1.0 but I could not find the schematics for the Rev 2.4. I tried to look for similarities in the Rev. 1 but there are somethings missing, plus the board i have has nearly no component names printed on it which as a newbie makes pretty hard for me to locate things. Any assistance will be appreciated. Thank you.

          If anyone needs schematic diagrams for any pro audio gear like what professional musicians use, such as guitar amps, power amplifiers, vintage tube amps, musical gear like keyboards, effects pedals, guitar wiring diagrams and service manuals, check out https://schematics.ca . I'm a road musician and an electronics tech and I got schematics for just about every piece of gear in my band from this site and they are free to download. It's always good to be prepared in case you fry something while on on the road, which always happens it seems. https://schematics-free.com has a lot of free audio schematics...
