Power Supply 2 Amp, Circuit Protected cr2s6

If you do not know how to determine the correct size that your power supply needs to be, you have a couple options. First purchase my instructional manual and read Know How Many Lights You Can run On Your Transformer or simply buy a bigger unit. Since all of the power supplies I sell are voltage regulated, it makes no difference if you only have one light attached. That light will not burn out prematurely because it receives too much voltage as is true with an older transformer.
I highly recommend and only sell 12 volt Direct Current (DC) power supplies. All are 12 volt, voltage regulated circuits. I secondly recommend that your power supply be a circuit protected power supply. Circuit protected means that if you introduce a full short across the unit, it will shut down but can be reactivated simply by unplugging it and plugging it back in. CR2S sells only DC regulated power supplies: A 1 amp (12 watt), 2 amp (24 watt) and 6 amp (72 watt) regulated power supplies. Unlike the older transformers, you can buy a larger, more powerful unit and not worry about your lights burning out. All of these power supplies put out a constant 12 volts.
For most projects I recommend the 2 amp, voltage regulated and circuit protected power supply that I sell for $ 28.98. For those larger dollhouses or to power several display boxes, I recommend the 6 amp, voltage regulated, circuit protected and line grounded power supply.
