Instruction for DC/DC converter TDC -Dc-dc

The TDC-X High Efficiency Series DC/DC Converter are specifically designed to provide a reduced voltage supply for auxiliary electrical systems in electric vehicles. By adapting the internationally advanced digital analogy technology, it has the excellence of high transition efficiency, minitype, easy to install, open circuit operation for long time, lower static power, stable output voltage, larger capacity, well-found protecting function, high stability and long lifespan. Employing soft key technology, it has the functions of fail safe for low-voltage, short-circuit protection, overheat and overcurrent protection. High transition efficiency, allowing sustained short-circuit, reset after unshorting are its advantages.
