The RG40 is a solid-state, DC to DC switch-mode converter that converts an input DC voltage (27.5 VDC nominal) t
o a regulated 13.75 VDC output voltage.
The RG40 meets the Federal Aviation Administration (FAA) technical standard order TSO-C71 (airborne static DC to DC electrical power converter - for air carrier aircraft).
Two or more RG40's may be paralleled (external diodes required) if additional power is required.
RG40
Specifications:
Input Voltage:
22 to 41 VDC (27.5 VDC nominal)
Input Current:
18.1 ADC at full load (nominal)
Output Voltage:
13.75 VDC
Output Current:
30.0 ADC at full load
Output Ripple:
13.75 mV
Efficiency:
80% (minimum)
Load Regulation:
1% Line, 1% Load, 1% Temperature
Load Transient Response:
NL to FL condition: 4.0 Vp undershoot for 5.0 mSec. (nominal).
FL to NL condition: 2.0 Vp overshoot for 5.0 mSec. (nominal).
Overload Capacity:
110% of the rated output power for a period of two hours; 150% of the rated output power for a period of 5 minutes ( 1 min. at 70°C ambient temperature). Without damage or degradation, the converter will withstand a sustained short circuit and provide 200% of the rated output current for a period of one minute.
Protection Circuit (Reverse Polarity):
The converter will trip a MIL-C-5809 25 ADC input circuit breaker in the event of reverse polarity input voltage connection.
Protection Circuit (Shut Down):
The converter will shutdown under the following conditions:
Input voltage > 41 VDC (-3 VDC hysteresis)
Input voltage < 15 VDC (-2 VDC hysteresis)
Output voltage > 16 VDC (-2 VDC hysteresis)
Internal temperature > 100°C.
