TSO'd REGULATED DC-DC POWER CONVERTER
(14 to 28Vdc High Power DC Converter)
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.
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.
Normal: 12 to 28 Vdc
Abnormal: 8 to 36Vdc
21.8 Amps typ at 14 Vdc input &@FL
(0.5 Amps maximum at no load)
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
28 ± 0.5 Vdc regulated for input voltage from 8 to 28 Vdc (Switching Mode)
Follows input voltage for the input above 28 Vdc (Override Mode)
0-10 Amps continuous.
15 amps for 5 minute.
280 Watts continuous for input voltage from 12 to 28 Vdc.
420 Watts for 5 minutes at 14 Vdc input voltage
1% for line, 1% for load and 1% for temperature
Delivers 110% output power for 2 hours minimum
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.
Unit is protected against output short circuit by an external 25 Amp input circuit breaker per MIL-C-5809
