Same power supply question... reworded. Thanks for having patience

There are numerous post war Lionel transformers with pure sine wave constant output voltages in that range, e.g. #1033.  It's advisable to install a fast acting fuse/breaker between PW transformers and the TIU.

Anything with a physical secondary tap wiper or fixed taps in that range will work.  A good modern choice with some real versatility would be the Atlas/Williams 80 watt transformer - built like a postwar transformer with two variable sine wave outputs, and whistle/bell capability.

Thanks guys. That one looks good, but I need to beat a dead horse.

If I use the accessory tap on this at full power, it will put 16V on the TIU or the MTH IR controller and it wont be chopped? Is that correct? Is that what pure Sine Wave means?

 

Also the 14VAC Accessory output on a Z1000 won't do what I want, is that correct?

 

I don't know why this is so difficult for me to grasp...

 

Thanks

It will put out 16V on the accessory connection, but only 2 amps, and it is pure sine wave.  The track output is at least 5 amps.

 

The Z-1000 I believe does chop the brick's output electronically to 14 volts.

Thanks Rob! You hit the topic in both Forums. Much appreciated

It is not the. Z1000 brick that chops the sine wave, rather, it's the Z-Controller throttle. The Z1000's accessory output is a pure sine wave, not chopped.

Barry, I stand corrected.  I knew that the brick outputs 18v, but was not aware the 14v output connection is on the brick, separate from the controller.   The manual is vague, if not completely lacking, in accessory connection instructions.

 

The Lionel BW, CW, and GW all make the accessory connection at the controller, resulting in other than pure sine wave outputs.
