General Electrical FAQ
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.
FAQ (Frequently Asked Questions)
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.
Dapper: Frequently Asked 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.

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.

The differences between AT & ATX power supply are the connector and output voltage. ATX is has a 20-pin connector for mainboard power while AT has two six-pin connectors. ATX has a 3.3V output and +5Vsb, but AT doesn??t. power supplies come with an on/off switch. ATX power supplies is not necessary. The on/off switch of ATX units is controlled through the motherboard. However, some models of ATX power supply do come with it.
Voltage Converter - Frequently Asked Questions
On the back of your appliance, you will find a label describing the power requirements. You should see a label describing the Wattage (W) or the Amperage (A) of the appliance. Once noted, choose a voltage transformer / converter which can handle a higher amount of wattage then your device is rated at. Certain devices which are motor based may require additional power to start up then indicated (know as Surge), in this case always add an extra 20% to the power requirements of your device.

Yes, as long as total wattage of all your appliences does not exceed the wattage capacity of your transformer/converter. Try to set up your transformer to run at 80% of its wattage to avoid demaging your appliences by power flunctuations.

In speaking general Voltage Converters and Voltage Transformers are used to convert electricity. North America and some other countries operate on 110/120 Volt AC 60 HZ. While most of the world operates on 220/240 volts AC 50 HZ. Voltage Converters change the electricity to make work electrical appliances in different countries.
Garden Lighting Frequently Asked 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.

A transformer between 14Vac and 16Vac. For a typical installation, the minimal power required is 40Va.
Elecraft K3 FAQ
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.

The difference between ATX and Micro-ATX are the form factor and output voltage. Micro-ATX provides 4-output voltage (+5V, +12V, -12V, and +3.3V). ATX provides 5-output voltage (+5V, +12V, -5V, -12V, and +3.3V).
Answer: 4-pin power supply connector fan is more universal. You always have power supply connector. You can daisy chain many 4-pin fans together and only use one of your power supply connector. If you buy 3-pin motherboard connector fan, you need to make sure your motherboard do have the socket for the 3-pin fan. Each socket can only connect to one fan. The reason you want to buy 3-pin fan is you can take the advantage of fan speed control by your motherboard.
