Serial Control Record.
Silicon Controlled Rectifier. A semiconductor device used to convert AC to DC. Commonly used in motor drive applications and UPS
This term has two separate and distinct meanings: 1) A solid-state semiconductor component that conducts or resists current flow depending upon whether a trigger voltage is present at the gate terminal. 2) A complete power controller that utilizes SCRs or TRIACs as the switching devices to control current flow.
Silicon Controlled Rectifier. An electronic switch that can be turned on and off very quickly (up to 300 times a second) that allows current to pass through in one direction.
Silicon Controlled Rectifier -- a three-electrode solid-state device which permits current to flow in one direction only, and does this only when a suitable potential is applied to the third electrode, called the gate.
Silicone Controlled Rectifier.
Typically used in a back to back configuration in order to control both the positive and negative half cycles of an AC line.
Silicon Controlled Rectifier. A solid state switch, sometimes referred to as a thyristor. The SCR has an anode, cathode and control rectification since it can be turned on at will. The SCR can rapidly switch large currents at high voltages. It is small sizes and low in weight.
Ssilicone controlled rectifier.
Silicon Controlled Rectifier. A reverse blocking triode thyristor pnp device.
Silicon controlled rectifiers. A type of diode..
A solid state electronic remote controllable dimming device. An SCR is essentially an electronic switch which achieves the affect of dimming by turning an electrical circuit on and off rapidly over a specific time interval. Most SCR dimmers can only be used to dim incandescent lamps. Other electronic dimmers use similar devices under other names such as the SSR, and include many other sophisticated electronic filtering, control, and circuit monitoring and protection circuitry.

silicon-controlled rectifier, also known as a thyristor; like a diode it only allows electric current to flow through it in one direction, but in addition it can be controlled so that its "turn-on" can be delayed indefinitely.
Silicon Controlled Rectifier. A semiconductor diode in which current through a third element, called the gate, controls turn-on, and the anode-to-cathode voltage controls turn-off.
Semi-closed Circuit Rebreather
Silicon controlled rectifier. A PNPN silicon junction rectifier whose forward characteristic can be triggered from the blocking state to the conducting state by a pulse applied to a gate electrode.
Abbreviation for silicon-controlled rectifier. Three terminal active device that acts as a gated diode. The gate terminal is used to turn the device on allowing current to pass from cathode to anode.
