Low Voltage Electrical Wiring & Lighting Systems - InspectAPedia
Photo: typical line voltage (120VAC or 240VAC) electrical wiring used in wiring a building 14A or 20A electrical circuit. The "normal" building electrical wires, typically #14 gauge (for 15-Amp circuits), is used to carry electrical power into and then out of the low-voltage relay and on to the light, electrical receptacle, or other device that
Switching Power Supply Circuit Diagram with Explanation
Jul 13, 201910.3 Output Voltage Limiting Protection Circuit. The output voltage limiting protection circuit is as shown in the figure below. When the output voltage rises, the Zener diode and the optocoupler turn on, and the Q1 base turns on with a driving voltage. The voltage of UC38423 rises, the output decreases, and the Zener tube does not conduct.
