Power DC/DC converter RH28

regulatedPWMhigh-power

The KGS model RH28 converts 14 Vdc input voltage to a regulated 28 Vdc output voltage. The converter is capable of delivering 280 Watts continuously at 28 Vdc and up to 10 amperes output. DESCRIPTION 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. Because of the design topology, a wide input voltage range is possible while delivering highly regulated 28Vdc output power. Specifications Input Current 21.8 Amps typ at 14 Vdc input &@FL (0.5 Amps maximum at no load) Overload Unit will not suffer damage or degradation in performance from an overload input current of 50 Amps for 5 Sec or until a 25 Amp input circuit beaker trips Output Voltage Follows input voltage for the input above 28 Vdc (Override Mode) Output Current 0-10 Amps continuous. 15 amps for 5 minute. Regulation 1% for line, 1% for load and 1% for temperature Overload (OL) Delivers 110% output power for 2 hours minimum Protection (OL): Withstands without damage or degradation, loads exceeding 110% of the rated current. Output voltage falls toward input voltage when load exceeds 20 Amps. Unit delivers rated output power upon removal of the overload (OL) conditions. Protection (SC) Unit is protected against output short circuit by an external 25 Amp input circuit breaker per MIL-C-5809 Efficiency 92% typical Temperature -55° C to +71° C Altitude 55,000FT Compliance FAA TSO-C71
