Can I build my own transformer?

Dapper: Frequently Asked Questions
Yes. Transformers are tools which transform the raw XML produced by Dapper to various useful formats. Soon, we will release the code of the existing transformers and an API that will allow you to build new transformers and add them to the current existing list.

In the transformer section, what does C.T. mean?

Hammond Mfg. - FAQ Section (Frequently Asked Questions)
C.T. is short for center tapped. The center of the winding has been brought out of the transformer via a wire lead or termination.

What size transformer or power supply do I need ?

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.

Q49. What is a dependency transformer?

Smalltalk FAQ
A DependencyTransformer implements the behavior needed by an object to register interest in a value model. A dependencyTransformer is defined as a dependent of a value model and converts an update message sent to itself into a specific change message and sends this change message to the interested object.

What is a PCB transformer?

PCBs | Region 9: Toxics | US EPA
Polychlorinated biphenyls (PCBs) were used in electrical transformers manufactured between 1929 and 1977, with the majority being installed in residential and commercial buildings and industrial facilities prior to 1978. A “PCB transformer” is a transformer that is known, or assumed under TSCA, to contain PCBs at concentrations greater than 500 parts per million (ppm).

Do you own a PCB Transformer?

PCBs | Region 9: Toxics | US EPA
Generally, a transformer will have a nameplate attached to the unit indicating the name of the dielectric fluid, the approximate weight in pounds, and the amount of fluid, usually in gallons. In accordance with the Toxic Substance Control Act (40 C.F.R. ยง 761.40 (a)), proper PCB identification labels must be visible near the access to the transformers and also on the transformer itself.

What is an electronic transformer?

FAQ
Conventional transformers, also called electromagnetic transformers are extremely large and heavy, and consist of an iron core and the sets of wire. An electronic transformer, on the other hand, also contains an electronic device, an inverter, which allows the size of the actual transformer to be reduced. This electronic device and the reduced size output transformer make up the main components of what we normally call an electronic transformer.

What is an isolating transformer?

Frequently Asked Questions - Jefferson Electric
In an isolating transformer, the primary and secondary windings are connected magnetically, but not electrically. Also referred to as an "insulating" transformer.

What is a dependency transformer?

Smalltalk Frequently Asked Questions
A DependencyTransformer implements the behavior needed by an object to register interest in a value model. A dependencyTransformer is defined as a dependent of a value model and converts an update message sent to itself into a specific change message and sends this change message to the interested object.

Do any of your Monopoints / Multipoints allow the use of a remote transformer?

Frequently Asked Low Voltage Monorail, Mono/Multi -Point and...
Our QMP-M1RN-TR and QMP-MI Monopoints allow the use of a remote low voltage transformer. The Multipoints all have integral electronic low voltage transformers.

Which jumpers do I cut when installing a TF 407 or TF 410 transformer (for the MA 3)?

Technical Support
You MUST cut wires W6, W8 and W13 for channels one, two and three respectively. Additionally you may wish to cut W9, W10 and W14 to break the minus connection from primary to secondary. See the TF 407, TF 410 Manual for installation instructions. I can't tell which terminals to connect to the amp on the 70.7 transformer (models TF 170 and TF 370 for the MA 6S).

What are bridge and transformer skeletons?

MC-3020 Model Compiler FAQ
From the MC-3020 UG:) Based upon information modeled in BridgePoint Model Builder, MC-3020 automatically generates source code frameworks for bridge and transform implementation. These skeleton files will actually compile as generated. The user is saved from delving into generated code to divine interfaces required for these boundary functions. Kind and helpful comments are provided to guide insertion of bridge and transform implementation code.

How do I evaluate the Geographic Transformer?

Geographic Transformer
You can completely evaluate version 4.x, including image reprojection, with any ONE of your own images, or with any of the sample images provided within the new, enhanced Getting Started Guides.

How many lights can I power from one transformer?

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.
