The DCPM-1 is a versatile linear power module. It can be used to power DC Board Cameras, Miniature Fiber Optic Transmitters or Access control products such as Door Readers and REX'S. To power the unit, you simply apply 10 - 28V AC or DC power to the input and you get 5v or 6-26 VDC with up to 1A output (see Output Current graph). A typical CCTV application could have our PDA-8ET4 powering 7, 24 VAC cameras and then a wire run to a covert board camera powered by our DCPM-1. An access control application would be where you have 24 VDC lock power and you use a DCPM-1 to power a lower voltage REX and/or door reader from the 24 VDC source.
