Switch Mode Power Supply – A New "Unconventional" Design Launched by CET Technology
A typical Switch Mode Power Supply (SMPS) or switching supply has an input of ~120VAC to 240VAC and outputs a low DC voltage of say 5, 12 or 24V. Recently, a major fire & security hardware manufacturer approached CET for a more "unconventional" supply that had a low input voltage of 24VAC and required high current, 2.5 amps at 5VDC output. Unconventional, because most switching power supplies do not run in such low AC input voltage.
