Battery type
Anderson Power mating part PP45 or equivalent
1. Capable of operating at 73% of rated full load for up to 2 hours at 74°C. For FXM350, above 55°C ambient, derate output power by 1.4%
per °C rise, up to 74°C max. For Micro350 derate above 50°C
2. Capable of operating at 100% of rated full load below 0°C down to -40°C after the Alpha FXM350 and Micro350 has been stabilized at
0°C for at least 1 hour. Batteries may need battery heater mat at lower temperatures.
3. Derate 2°C per 300 m (1000 ft) above 1400 m (4500 ft).
4. The LCD display may not function below -15°C. It gradually resumes normal operation as the temperature rises above -15°C. This will not
affect the operation of the Alpha FXM.
5. Efficiency is measured at an ambient temperature of 25°C, full resistive condition and nominal Line and Battery voltage.
