Model Theatre Lighting Dimmer
This circuit serves as the foundation for the dimmers in a model theatre lighting system that utilizes touch globes as the light source. The circuit is centered around a 55.
This circuit design incorporates a dimmer functionality specifically tailored for a...
Simple Lamp Dimmer Fan Regulator
The circuit operates by adjusting the firing angle of the Triac. Resistors R1, R2, and capacitor C2 are involved in this process. The firing angle can be modified by changing the value of any of these components, with R1 designated...
2500W Phase Control
This circuit controls resistive and inductive loads up to 2,500W. Its primary component is the Siemens TLE3103 integrated phase control circuit, which includes its own power supply, a zero voltage crossing detector, and a logic driver. An additional feature is...
How to test a triac
A multimeter can be utilized to assess the condition of a triac. Begin by setting the multimeter selector switch to a high resistance mode (for example, 100K). Connect the positive lead of the multimeter to the MT1 terminal of the...
Light Sensitive Staircase Switch with Triac
Light Sensitive Staircase Switch with Triac. The operation of the third circuit is similar, except that it incorporates photo sensitivity. The circuit is illustrated in the schematic. When there is insufficient light...
A light-sensitive staircase switch utilizing a TRIAC is designed...
BA5173 produced by multi-function lamp dimmer
The circuit operates on a 220V AC input, which is stepped down by a buck converter using resistor R3. The output voltage is rectified by a VDI rectifier and filtered through VD2 and capacitor C3, providing approximately 3.9V DC to...
Hysteresis-free phase control circuit
This circuit is designed for lamp dimming and similar applications. It requires only one RC phase lag network. To prevent the hysteresis (or "snap-on") effect, the capacitor is reset to approximately 0 volts at the end of every positive half...
Triac Applications
Next to SCR, the triac is the second most commonly used component in the thyristor family. It has largely replaced SCR in many control applications due to its bidirectional conductivity. Key applications include motor speed regulation, temperature control, illumination control,...
Simple silicon-controlled dimmer circuit diagram
A simple silicon-controlled rectifier (SCR) dimmer circuit is depicted in Figure 13. This circuit is designed to control the brightness of lights. As the resistance in the potentiometer decreases, the conduction angle of the SCR increases, resulting in an increase...
