The PDC2412003 is a DC/DC power converter that takes 24V DC input and will output 12V DC. Cuts DC power to create low amperage, regulation output. Low heat, with synchronous rectification technology. Full load efficiency above 90%, small size, just 46 x 32 x 22mm with insulated plastic heat-sink enclosure. Cost effective for DVD, GPS, LED Panels, etc. This power converter will operate at lower voltages with reduced current output. We frequently recommend this power converter for operation with a 12VDC input to help isolate troublesome power related issues.
