SCR Controller Description & Design | Hockey Puck SCR's ... The SCR The heart of the SCR power controller is the SCR (silicon controlled rectifier, also sometimes referred to as a thyristor). The SCR has two states, ON or OFF, and it allows current to flow in only one direction. SCR's can remain in the off state even though the applied potential may be several thousand volts. Silicon controlled rectifier The name "silicon controlled rectifier" is General Electric's trade name for a type of thyristor. The SCR was developed by a team of power engineers led by Gordon Hall and commercialized by Frank W. "Bill" Gutzwiller in 1957. SCR Power Controllers for Electrical Resistance Heaters The controllers consist of power semi conductors (SCRs), properly sized heat sinks, trigger circuitry, and fuses supplied on panels for surface mounting. The power controller accepts a 4 to 20 mA dc output from a temperature controller or can be supplied with manual option using a remote potentiometer. WHAT YOU SHOULD KNOW ABOUT SCR POWER CONTROLLERS The SCR power controller can control the average load voltage, the RMS value of the load voltage, the RMS or the average load current or load power. The Silicon Controlled Rectifier (SCR) | Thyristors ... REVIEW: A Silicon Controlled Rectifier, or SCR, is essentially a Shockley diode with an extra terminal added. This extra terminal is called the gate , and it is used to trigger the device into conduction (latch it) by the application of a small voltage.
