Voltage Comparator Information And Circuits
This page provides basic information about voltage comparator integrated circuits and is to act as reference material for other circuits.

 


voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level.

Voltage
Voltage is an electric potential difference between two points, the unit of measure is the volt.

ABOUT VOLTAGE
A few words about voltage may help you understand the operation of your transformer so that you can use it to the best advantage.

Voltage
Electromotive force (analogous to a pressure) measured in volts.
Voodoo Barge ...

Fixed Voltage Post
In model railroading, a terminal post on a transformer or power pack which is permanently configured to provide a set amount of voltage at all times. Generally used to power accessories and lamps.

The induced voltage theory is a strong voice for lights in our locomotives. If we can reduce track cleaning by lighting our motive power, why not do it and smile?

Changes high-voltage 110-volt AC house current into low-voltage AC current to power your DCC system.
Transition curve
See Spiral curve or easement.

Use a variable voltage transformer to change the voltage supplied to the main winding if you desire a high slip, reduced voltage speed control, which is more efficient.

Impedance Bond An electrical track device used to separate the spent high voltage DC return voltage intended for the substation from the low voltage track circuits or other circuitry. See also AFO.

This is not a true DC offset, but does change the RMS (average) voltage to a non-zero value. That is sufficient for whistle relays of that era.

126 ton dual voltage CoCo electric locomotive which can obtain power from a catenary or a third rail. Used for Channel Tunnel freight services.
Class 101
RAILWAYS. A type of diesel railcar, used in Britain.
Class 159
RAILWAYS.

Semi-Conductor - Material used in electric traction rectifiers, whose electrical resistance depends on the direction of the applied voltage. Silicon and Germanium are typical examples.
Seniority - Length of service relative to others.

A low-voltage flow of electricity in the rails of a track when they are bonded at the joints and form a complete circuit.
Catch basin.

May use constant voltage on the track with a device on the engine receiving a radio signal from the controller telling it how much voltage to use and which direction to go.

The simple track circuit consists of a relay energised by a low voltage circuit fed through the running rails of a section of track. Each section is electrically isolated from others.

Transformer The unit which converts the household mains voltage down to the much lower and safer voltages that we use to run our trains.

According to this guy at the UP, the cut out was supposed to be located behind the high voltage cabinet inside the little room there.

Many modelers have found ways to make that light burn constantly, or at least at a constant voltage. Most methods use diodes and/or resistors to step the voltage down or keep it constant.

On model trains, the headlight intensity may vary with the voltage on the tracks.

The detector reduces the track voltage by 1.4 volts due to the bridge rectifier. This can actually be an improvement with conventional throttles, reducing the (usually too high) top speed of engines.

Make sure your lamps can handle the voltage from the power source; otherwise they will burn out quickly unless you put a resistor in the circuit. This is especially true for LEDs.

Voltage determines speed. Electrical rating (measured in voltamps, VA, meaning volts x amps) is what matters.

A location where power is received at high voltage and changed to required voltages and characteristics for distribution to the catenary system, third rail, and other electric apparatus.

If you have a "train set" power pack, these are usually 7va with 15-17v DC voltage. This should provide enough power for about 20-30 miniature Christmas tree lights wired in series, five lights to each series.

Feeder Wire--smaller gauge wire (usually #22 or #20 - the lower number is thicker wire) that feeds from a main wire under the layout up to various points along the track to preclude voltage drops and maintain constant current.

For electric locomotives and multiple units notching up describes the process of increasing the voltage on the traction motors in steps. This can be done manually or automatically.
