In stock 20 Watt Fully Isolated DC/DC 12 Volt Converter bricks at 1/2 price

12 to 12 volt converter mounted on the circuit boad 
Complete product with circuit board and wire terminals Bare module ready for mounting on a circuit board is also available
_________________________________________________________________________

This is a fully isolated 12V to 12V DC/DC converter module, or "brick." It has 1600 volts isolation from input to output, has a standard footprint, and a wide voltage input of 9-18VDC. The 12 volts output is at 1670 mA, giving 20 watts. It has automatic recovery from power overload protection, which kicks in at about 24 watts.


The short circuit protection is done by an automatic recovery "hiccough mode," meaning that when it detects an overload it tries to come on, then if the fault is still there it will shut off. This happens continually until the fault is corrected.

This is perfect for regulating 12 volts from battery or automobile voltage sources. We can also supply the circuit board to mount these to, the Gerber files are linked below.
These are high quality, brand name Taiwanese converters in a polished nickel plated copper case. Shielding is on all 6 sides.
