High efficiency 24VAC to 12VDC 20 Watt AC/DC Converters with removable screw terminal block (also a 36VDC to 12VDC DC/DC converter)


24VAC to 12VDC 1.5 Amp power source
24VAC to 12V 18 watt power supply 24VAC to 1V, 3V, 3.3V, 4V, 4.8V, 5V, 6V 8V, 8.4V, 9V, 10V, 11V, 12V, 13V, 14V, 14.4V, 15V, 16V, 17V, 18V
24VAC input, user adjustable DC output, including 5V 5A, and 12V 3A

Tiny switchmode 24VAC/12VDC power supply offers much higher efficiency and lower ripple than the cheaper linear versions. The biggest application of these is to power 12 volt video cameras to replace 24VAC cameras, fiber optics transmitters, REX PIR's, proximity readers and other accessories. Also works as a 36VDC to 12VDC converter.
