REGULATED DC TO DC POWER CONVERTER
FAA TSO-C71
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.
| 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).
