The main purpose of your power supply is to run your trains. To run your train your power supply must supply energy for your locomotive, smoke unit, sound system , and any lighted cars. You may also need power for accessories like switches, street lights, building and house lighting or any other accessories. Your TOTAL POWER REQUIREMENTS depends upon the number of locomotives or motors, and ALL OTHER items that require electricity. The length of the track is not a factor.

No, the 810 and 820 series meters operate in using a "single ended supply" meaning you only need between 9 and 25 VDC to operate them. We sell very reasonably priced power supplies that accomplish this in a very economical manner. See similar questions...

A Transformer is an electrical device by which alternating current of one voltage is changed to another voltage using coils. There are several different types, but they all basically do the same thing - change the voltage. They are usually heavy for their size due to the weight of the coils (size and weight depends on their rating). A Converter is an electronic device that is used in some cases instead of a transformer. See similar questions...

A transformer is a tool that takes the output of a Dapp and converts it to another format. Current transformers include: RSS, email, HTML, Google Maps, and more. To transform a Dapp, find or create a Dapp and then click the 'more uses' button to see the available set of transformers. See similar questions...

Many people use the wrong size cable for their systems but working out what power cable you need is actually very simple. Add all the ratings together. ie total each amp so a 2x50wrms amp would be 100, then add the totals together. This gives you a number representing the current draw, in amps, of your system. Then match the current with the length of the cable in the following table to give you the correct size cable to use. See similar questions...

In fact, transformers are available in a wide range of wattage ratings, so we need to look at the question the other way around: "what size of transformer do I need to power the group of lights required"? This is simply a matter of multiplying the wattage and numbers of the lamps used in the luminaires (garden lighting fittings) to be connected to the transformer. For example 6 light fittings at 20 watts = 120 watts in total. Therefore a 150 watt(va) transformer is required. See similar questions...

Yes. If the Roll-Up III connects via serial port, the external power supply is needed to ensure the digitizer has a constant power source. This is especially true if you are using the digitizer with a laptop computer. The power supply is not needed if the Roll-Up III connects via USB port. See similar questions...

Yes. Although the Roll-Up does get some power from the computer, the external power supply is needed to ensure a constant power source. This is especially true if you are using the digitizer with a laptop computer. See similar questions...

The K3 DC voltage required is 13.8 V nominal/recommended; 11 V recommended minimum; transmit disabled below 10 V; system shutdown below 9.0 V. The K3 is portable, thus it's designed for operation with a 12-V vehicle battery or gel-cell. Estimated minimum current draw with no enabled options is 0.9 A on receive, 3 A at 10-W and 20 A at 100-W. These figures will be refined after further testing. On all HF bands, TX with a 12.0-V supply still allows 100 W+ output. See similar questions...
