Regulated DC-DC Power Converter | 28/14VDC, 280W
K G S ELECTRONICS
EDMO#: RG28
MFR#: RG28
Description
The RG28 converts 28 VDC input voltage to a regulated 14 VDC output voltage.
The 14 VDC output is buck converted from the input voltage and therefore the output voltage is not isolated from the input.
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.Features
- Converts 28 VDC to 14 VDC
- 280 W continuously at 14 VDC (20 amperes output)
- Synchronous current mode switching
- Surface mount technology
- Output short circuit current limit protection
- Output shuts down when the voltage feedback loop is opened
- TSO'd
