Large Buck-Boost DC/DC Converters

High power 12 volt to 6 volt, 12 volt to 12 volt, 24 to 24 volt, and 24 to 19 volt DC/DC Buck-Boost converters at low cost. Suitable for voltage stabilization of automobile electronics, special purpose UPS, etc.

These are Buck-Boost DC/DC Converters. Buck-boost means that the topology will alow the DC input voltage to be higher or lower than the output voltage, which makes the design very flexible for semi-custom designs. For example, you can specify a factory set output voltage from 13.8 to 24 volts with a minimum order of 10 pieces.
Motors: Running motors from these units will void the warranty.

Advantages:

Designed for converting an unregulated/unstable dc voltage to a regulated dc voltage.
Suitable for marine and automotive applications
Isolated with input and output common ground
Good load and line regulations
Wide input voltage input range
Fully electrical protected
Anodized blue colour aluminium extrusion housing

Inexpensive high current DC/DC converter stabilizes voltage in automotive and truck applications.

Also can be used to provide regulated voltage from a sealed lead acid or other battery--excellent for special purpose UPS DC battery backups.

High efficiency 75-85%.
