RG40 Power Converter Regulated DC to DC
(KGS products can only be shipped to U.S. address only.)
(DAI Part# RG40)
The RG40 is a solid-state, DC to DC switch-mode converter that converts an input DC voltage (27.5 VDC nominal) to a regulated 13.75 VDC output voltage.

The RG40 meets the FAA technical standard order TSO-C71.

Two or more RG40's may be paralleled (external diodes required) if additional power is required.

SPECIFICATIONS
DRAWING
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 temp.) 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
(Shutdown)
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)
