See Transformer. An isolation transformer has an equal number of windings between the input and output coils. The output voltage is therefore the same as the input voltage. Since magnetic fields are relatively slow to change, an isolation transformer can protect circuitry from damaging electrical noise.
A transformer with a 1:1 (one-to-one) power ratio. That is, the signal level going in equals the signal level coming out. Commonly seen used in direct boxes or microphone line splitters. This allows the same signal to drive different inputs such that they two inputs don't interfere with each other, but are isolated from each other.
A transformer in which one or more output windings is electrically separated from the input winding and all other output windings by an insulation at least equivalent to double insulation or reinforced insulation.
an electrical device that sits between the power connections of the monitor and the electrical feed
a special transformer that is designed so that the signal going out equals the signal going in
a very unique transformer
A device that electrically separates electronic equipment from the incoming power system, reducing unwanted electrical noise.
A transformer inserted to reduce noise and isolate a circuit. These are used in many larger uninterruptible power supply (UPS) systems.
A device that electrically separates and protects sensitive electronic equipment by buffering electrical noise and re-establishing the neutral-to-ground bond. By virtue of the neutral-to-ground bond, isolation transformers eliminate neutral-to-ground voltage - one type of common mode disturbance.
A transformer with a 1:1 turns ratio. It does not step voltage up or down. It serves as a safety device, isolating the grounded conductor of a power line from a chassis or any portion of a circuit load.
A transformer in which the primary winding(s) are isolated from the other windings such that a insulation breakdown either is unlikely or will not cause a hazardous condition.
Transformer with a one-to-one turns ratio. connected between the a.c. power input to a piece of equipment and the a.c. line, to minimize shock hazard.
A transformer that contains electrostatic shields between primary and secondary windings, and no direct electrical path between primary and secondary.
A transformer used to reduce or eliminate noise and create the equivalent of a dedicated or isolated ground circuit. These transformers are included in many larger UPS systems of 3kVA or larger. Standalone isolation transformers serve the function of removing common mode noise. See common mode voltage.
A multiple-winding transformer with physically separate primary and secondary windings. Although the two windings are physically disconnected, the magnetic field in the windings of the primary creates (induces) electrical power in the secondary winding. In this way the electrical power available at the input can be transferred to the output. An isolation transformer does not transfer unwanted noise and transients from the input circuit to the output windings. This attenuation, or reduction in amplitude, could be as high as one million to one. No Definitions No Definitions
A transformer with a one to one turns ratio, where one side is connected to the source and the other to the load. This prevents any DC bias levels present on the source from passing through to the load.
Transformer placed in series intended to provide electrical isolation for down-line critical equipment. It may also step-up or step-down the voltage.
This transformer has physical separation from the primary and secondary windings in order to allow magnetic coupling between isolated circuits and minimize electrostatic coupling.
A transformer that sits between the building electrical outlet and the monitor, isolating the monitor from the building electrical system. [ edit
An isolation transformer is a transformer, often with symmetrical windings, which is used to decouple two circuits. An isolation transformer allows an AC signal or power to be taken from one device and fed into another without electrically connecting the two circuits. Isolation transformers block transmission of DC signals from one circuit to the other, but allow AC signals to pass.
