Custom design and manufacture of state-of-the-art battery chargers, UPS, and
power supplies for OEMs in a hurry!
This is a fully isolated
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.
