Thetransformer reduces the voltage from mains to 12 VAC V A C (RMS). The Diode Bridge (known as a bridge rectifier) will convert 12 VAC V A C to 15 VDC V D C. The voltage is 2-√ 2 times minus two diode voltage drops higher than the input voltage because the rectifier output is the peak AC voltage, not the RMS AC voltage. 12V1A Power Supply Adapter, Waysse 1000mA 12W AC/DC Adapter,12W AC Switching Adapter Slim Design DC 12V Charger for CCTV Camera, LED Strip Light, Routers, Speakers, Home Appliances, Scanner 4.2 out of 5 stars 1,429. $9.59 $ 9. 59.
