Picture of product RG28

Part #: RG28






Regulated DC to DC Converter

Part Number :

  • Converts 28 Vdc input voltage to a regulated 14 Vdc output voltage.
  • Capable of delivering 280 Watts continuously at 14 Vdc (20 amperes output)
  • 14 Vdc output is buck converted from the input voltage and therefore the output voltage is not isolated from the input
  • "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
  • Output shuts down when the voltage feedback loop is opened


Dimensions: 2.75 W x 6.875 L x 2.24H Weight: 1.2 lbs.
Input Voltage: 28 Vdc NOM., 22 to 32 Vdc Input Current: 10.8 Amps typ at 28 Vdc input & full load
Output Voltage: 14 Vdc regulated Output Current: 0-20 Amps continuous
Efficiency: 92% typical TSO: C71
Regulation: 1% for line, 1% for load and 1% for temperature Cooling: Convection and thermal conduction through the bottom plate (No internal fan)
Altitude: 55,000 ft. Temperature: -55°C to +71°C
Overload Protection: Withstands without damage or degradation loads exceeding 110% to an output short circuit. Unit delivers rated output power upon removal of the overload condition Overvoltage Protection: Under a output short circuit condition, the current is limited to approximately 37.5 Amps

In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.
