Windham, NH -- (ReleaseWire) -- 08/07/2015 -- 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.
The need came from their unique application. The customer had to implement the functionality of media converters using 24VAC power found on existing analog cameras. The location of the media converters with respect to the analog cameras can never be assumed near a standard AC outlet or DC source.
The media converters alter the analog picture data into encapsulated digital data for transmission over IP/Ethernet networks. The analog signal is transmitted to the media converter using fiber optics. Once there, the media converter performed analog to digital conversion, along with the proper TCP/IP encapsulation, for packet data transmission.
The packet data can then be transmitted over any distance, reassembled, and converted back to analog with no loss in fidelity or quality. The design and subsequent supply of this SMPS provided by CET Technology met the demands of the environmental and electrical specifications required for a stringent need within fire safety and security.
The part number of this power supply is CT-7186
How Switch Mode Power Supplies Work
A Switch Mode Power Supply (SMPS) or switching supply is an electronic power supply with integrated switching transformer to convert AC power into DC. The SMPS takes power from the mains source and converts and transmits it to DC powered electrical components. Switching supplies are extensively used in many industries across the globe due to their high efficiency and low power consumption.
Linear power supplies are good for low-power devices such as cordless phones and video game consoles. Although new video game consoles demand higher power so SMPS are being embedded in the latest generation consoles.
