Regulated DC-DC Power Converter | 28/14VDC, 280W

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
