Does anyone know how many amps the Starr-Tec 100 controller puts out? there are no other markings on the case. I know they had a 40 80& 100. Really don’t know what MW stands for. I know it’s not milli watts. I believe the company is out of business, so I’ll have to rely on you… Thanks…Jerry
How old is that controller? Google doesn’t turn up any such product, whether spelled as Star Tech or Starr Tech. MW is the official electronics abbreviation for milliwatts, and should not mean anything different…
The UL rating is in watts, or VA.
A milliwatt rating is pretty weak, and not good for much. You may need to replace.
WHAT ENGINE ARE YOU RUNNING?
I really don’t think it’s milliwatt… It runs 2 G gauge engines in the yard. It’s as heavy as the MRC 20. If MW is milli watt it wouldn’t even run one. They even put out a 40 MW. They are out of business…I’ve made searches also. It’s an orange box .has a switch for 14 or 20 volts & a telephone jack for the hand held controller which plugs into it, which is also orange with DIRECTION, BRAKE, MOMENTUM. Jerry
I’m not sure what MW stands for but they have decent power. I have one that is rated at 40 Volt Amps according to the side of the box. VA=ExI or Voltage x Amperage. If a typical maximum voltage draw of an HO engine is 12 volts, the math give my throttle rated at 3.3 amps. Thats enough to handle 3 or 4 old HO loco’s that my have drawn up to 1 amp each. Athearns in the last 10 years or so don’t draw more than about 0.5 amps so thats real good.
So in summation, the Starr-Tec Hogger marked 40MW on the side is 40 Volt Amps rating. They also made a 100 Volt Amp throttle.
Yes I have the 100 MW…so I assume it puts out 5a @ 20 v.
I have a friend who has one that needs service. We think that a resistor inside has burned up. The problem I am having is that the resistor burned the color off of the outside when it blew. Two possible helps. First can anyone take a high res picture of the inside of theirs. Especially the area near the front of the circuit board near the power transistor. That would help greatly. The other option would be to tell me if they know of a location of a schematic diagram of the circuits.
We do not want to have to redo the wiring on the layout (resistors for speed) for a new power supply, so we want to keep this one going if possible.
Thanks.
Side Note:
mW is MilliWatts
MW is MegaWatts
i have a hogger that i have had to replace a resistor twice. apparenty the hogger doesn’t have overload protection and if you make a short it will burn out a resistor on the circuit board. i tried to get it repaired at several hobby shops and was told that the hogger is not UL rated so they will not repair it due to insurance concerns. i opened up the case and found the burnt resistor but i could just barely read its value (22 ohm at 1/2 watt). i picked up a package of 5 at radio shack for $.99. now i still have three left. i don’t know if your problem is the same resistor but it is near the blue reversing relay and it sits between two diodes. hope this helps.
The one that burned on this one is in the front near the power transistor.
Thanks
I just purchased a 100mw from a hobby store, they had taken it back as defective because of a slide switch that had come apart (the high/low voltage). I repaired that, but tested it in both postions and it showed 20 volt output. Is there something else wrong? Only 2 wires go to the slide switch and I will only use it for HO, could I just solder the wires together for low voltage and by pass the slide switch? The unit appears to be brand new-never used, slide switch came apart from lack of pressure on the sides.
You mean they are still being made? wow!
