TSO'd REGULATED DC-DC POWER CONVERTER |
(28 to 14Vdc High Power DC Converter) |
| DESCRIPTION
The
KGS model RG28 converts 28 Vdc input voltage to a regulated 14 Vdc output
voltage. The converter is
capable of delivering 280 Watts continuously at 14 Vdc (20
amperes output). A state of the art "Synchronous Current Mode Switching" topology with Surface Mount Technology (SMT) is used to realize the power conversion. Control circuitry includes use of a popular Synchronous PWM controller for voltage regulation and overload current limit. Protection circuitry includes output short circuit current limit. The output shuts down when the voltage feedback loop is opened. |
