Hi can anyone help me with what appears to be a problem with a transformer for my mobile station one. It apears it doas not work and my mobile station will not work therefore!. can i use a normal Marklin anolouge transformer to work it or do i have to get a new one ie 66181.

Hello,
if I remember correctly, the MS1 needs DC, so you cannot use an AC transformer.

Isn't there a bridge rectifier in the "ugly box"? |

You can use any power transformer with stabilized DC output at 16V. Becareful with the amps the PSU supports, try one that has at least 2A current. Do not use AC plain transformer.

Hi Dan,
The original MS1 transformer is a regular 16 V AC transformer. Regrettably made in China, at least the safety input and output boards inside. The input board is a simple triac current limiting/soft start device, the output board has a glass encapsulated bimetal safety (overheating) cut-out switch. It is usually the triac or the zener diode on the input board that dies after a while. Repair is easy, just drill out the 4 plastic plugs on the sides of the housing using a fitting drill (keep the drill perpendicular to the housing and you can´t damage anything inside). Pull the top half off the housing. You will see the 2 boards. To be sure, measure the resistance of both the primary and secondary transformer winding on the transformer itself. Measure the resistance across the pins of the output connector. Should be the same as on the sec. winding. If not, remove the output board and either replace the bimetal switch or do away with the board alltogether and connect the sec. directly to the output pins.
If the sec. side is OK, take out the input board and replace or repair it or connect the mains wires directly to the primary winding, doing away with the input board. If you can´t repair the boards yourself go to any electronic or radio/TV repair shop and ask them to do it for you, it won´t take more then 5 min and about 50 cts in replacement parts.
Regards, Robert

I don't know the part number. |

My starter set came with a MS1 and a 16VAC transformer. It came with a power plug for the ugly box with stripped and tinned wires at the other end to connect to the push in connectors on the transformer. The ugly box does have a diode bridge rectifier in it to convert the AC to DC that the MS1 needs.

Hi Darren,
Sorry to correct that, but no, it does not have such a rectifier or any rectifier for that matter. In case you opened it up you are probably confusing the triac on the input board with a bridge rectifier. Look closely at the pcb, it says triac in small white print and it has 3 pins instead of 4. You may also be confused with the rail connection box, which is almost literaly a tiny bare bones booster.
regards, Robert

Robert, you are dead-wrong: The trafo has a Triac on the PCB; whereas the "uglybox" that Darren refers to has 4 diodes forming a bridge rectifier. Since we are talking about a MS1 here, there is NO booster in the "Uglybox"/rail connection box. And just to clarify: The MS1 works with both AC and DC.  Per. |

The 66181 power supply has a nominal output voltage of 18 V DC (it's not a transformer). Since it is not stabilized, you can measure 23 V output voltage without load. As Per said, MS1 can be used with AC or DC. I recommend 16 V AC or 19 through 22 V DC (stabilized power supply recommend, better stick to 18 V DC with unstabilized supplies). |

Hi Guys,
?? Well, I never realised Märklin had more than just 2 MS1 versions, the ones I know all have the 60 VA AC transformer 60052 (I think 60055 for 120V) in starter set guise and seperately available, difference being 1,2 vs 2Amp max rail output. I hadn´t looked at the article number for the transformer, assuming it would be the same that I have and which came with the 29811 starter set. So what I described is for the 60052, which in my case had that same problem 2 years ago. After removing the inpüt PCB it is still in use. Obviously I am not familiar with the other sets or the 66181... and I still don´t know what an ugly box is, other than UPS delivery vans but I suppose that´s a bit beside the point :-)
Regards, Robert

Hi Robert, The ugly box myself and others here are referring to is the 24088 C-track feeder.  We call it the ugly box because, well it is an ugly box strapped to the side of the track. It is more difficult to hide in a permanent layout. Using this box you can connect either a 16V AC power supply like the one that came with my starter set or a 18V DC power supply that came with some of the smaller sets. It contains the circuit board in Per's posting with the rectifier diodes. Cheers Darren

I have now got myself a replacement 66181 for £5 so i can get on and play trains! cheers Dan
