Voltage on coindoor electromagnets?

[CM]

I picked up an old over-under coindoor (old Atari one I believe), and it has separate wiring for the 12V lights, electromagnets (that keep quarters from going in when machine is powered off), and microswitches.  I hooked these to a spare 200W powersupply one at a time and the magnets would trigger at 12V but not at 5V. When I hooked up both magnets and both lights all together my powersupply wouldn't startup.   Is this too much of a load for 200W??  Anyone know specs for those magnets?

You didn't happen to hook up the microswitches to the power supply as well?  From what you said it sounds like you did.

haha .. no.   I don't think my IPAC would like that too much

Those are called coin "lockout" coils and are made in several voltages by the particular coin door manufacturer. Generally they are made in these voltages:

6 volts DC

12 volts DC

24 volts DC

48 volts DC

120 volts AC

The coils are usually stamped with the operating voltage and 12 volts DC was the most common ones. Generally the coild should pull in with at least 75% of it's rated voltage applied. If you tried to use a 12 volt coil on only 6 volts then it should NOT pull in as the voltage is too low. If I remember correctly I believe each coil draws around 500 milliamps of current.
