Push-pull converter (+12V → ±18V; 50W) as potted module. â‘ transformer; â‘¡ and â‘¢ electrolytic capacitors vertical and horizontal mounted; â‘£ discrete circuit board in through-hole technology. A push–pull converter is a type of DC-to-DC converter, a switching converter that uses a transformer to change the voltage of a DC
Catalog 40 of 1936 introduced a full line of architectural downlights (individual architectural products had been made for some time), the autotransformer dimmer (originally dubbed the "Transtat", the catalog was overstamped, changing the trade name to "Autrastat"), motor operated dimmers, Fresnel lens spots, etc. At the same time, the more ...
For example, an auto transformer that adapts a 1000 VA load rated at 120 volts to a 240 volt supply has an equivalent rating of at least: 1,000 VA (240 V – 120 V) / 240 V = 500 VA. However, the actual rating (shown on the tally plate) must be at least 1000 VA.
In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.
A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...
A common dual dimmer module used in stage lighting A dimmer. A dimmer is a device connected to a light fixture and used to lower the brightness of the light.By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.
