1. ePropelled The Future of
Electric Propulsion
Intelligent Power System - iPS500
Aircraft electronics continue to evolve as mission profiles become more
challenging and demanding. Longer flights and heavier payloads are
driving system designers to new heights. New levels of both energy and
system-level efficiencies are required to meet tomorrow’s aviation needs.
The 500-Watt ePropelled Intelligent Power Systems are a complete power
management solution for your aircraft. They provide steady regulated DC
power for your on-board avionics, servo and payload requirements. These
smart power systems also provide a wide array of real-time performance
and operational data for a range of useful applications and analytics.
ePropelled’s iPS500 provides complete power solutions for aviation applications.
The iPS500 takes in 3-phase sinusoidal AC voltages from starter generators like the
ePropelled SG500 and converts them to DC voltages to power on-board avionics,
servos and payloads. Input AC voltages will vary by the RPM of the Starter Generator or
Alternator and using active rectification and switching regulation the iPS500 will supply
the required DC output voltages.
Telemetry data for use with analytics, machine learning and artificial intelligence has
become a critical component to operational success of any air mission. The iPS500
monitors every input and output’s voltage and current level and provides the data
collected via an integrated Controller Area Network (CAN) interface. Aircraft and
power system designers can create custom applications via our open API (Application
Programming Interface) and you can set thresholds for alerts and alarms based on your
specific applications and mission profiles.
The Electronic Engine Starter (EES) feature can be used to drive the starter generator
during the engine start sequence. Once the engine is up to speed, the iPMC delivers
the regulated voltages. If for any reason the starter generator stops working, a backup
battery (if connected) automatically comes online and provides the voltages for a limited
duration depending on the backup battery size.
