Hi, i have a astron rs-12a 300 watt 13.8 vcd and aduracom. modle lp-10 7 amp continuos, what are they used for, can i use the to power accessories ogauge layout. Thank you

If you Google the model numbers, you will find out what they are and what they're used for.
I did, and determined that they are both 120 Vac input, 13.8 Vdc output power supplies. When you see "13.8" volt outputs on power supplies, that means 12 Volts in real life. Devices like two-way radios and other automotive equipment is rated that way, because car batteries are 12 Volts at rest, and require 13.8 Volts to get and stay charged.
If you have accessories that can operate at 13.8 Volts DC, then, yes, you can use these supplies to power them. If your accessories require AC at any other voltages, then, no, you can't.
These seem to be designed for electronics requiring a well regulated 12-14 Volt DC power supply, like Ham radio for example.
I would suggest not using them with accessories with coils (uncouplers for example), because 13.8 VDC can quickly overheat and melt these coils. It would be fine for 14 V incandescent lights.
What O gauge accessories would you want to use them with?
EDIT: Arthur, I started this reply before you posted yours. I agree with your statement.
Thank you for the replies, i wanted to power bldgs and lionel tower lights things that just stay on
The supplies can be used for those applications. You will have plenty of power for many of them.
Thank you for the info, Happy new year all.
Can you get inside the transformer and eliminate the diodes that convert the AC to DC?

Normally I try to encourage interest in electronics knowledge and experimentation. On this answer geared towards a novice, this is not one of those times.
With this much power, I'd strongly caution against anyone without proper training or the equivalent of a degree in electronics from attempting this. There is a significant risk of fire and possibly electrocution if you don't take the proper precautions, as is the case when modifying any high current device such as these DC power supplies mentioned by the OP.
Even opening the cover of an unplugged Power Supply can be dangerous if one were to come into contact with high energy capacitors which can retain a charge long after the unit is unplugged.
Can it be done, yes, but to ensure user safety, there's a lot more to it than removing the diodes. Doing so would bypass most of the built-in safety measures designed for DC current. And if you're asking this question, its a good indicator that you probably shouldn't attempt it without qualified assistance.
