Load Output Connection
The Hybrid UPS MicroTurbine’s electrical output to the critical load will automatically be
adjusted to match stable incoming utility grid power in both frequency and phase
relationship. Output voltage will be maintained at a preset value, regardless of incoming
utility voltage.
The maximum power need not be balanced. Loads can be connected 3 phases or single
phase and phase-to-phase or phase-to-neutral, so long as the current limits are respected.
An isolation transformer may be required, depending on the system configuration.
When utility voltage is unavailable, the output to the critical load will operate at the
selected voltage and frequency until the utility grid voltage returns and is stable. The
Hybrid UPS system will then automatically adjust its frequency and phase relationship to
match the utility again.
Power Quality
The MicroTurbine output conforms to IEEE 519-1992, IEEE Recommended Practices, and
Requirements for Harmonic Control in Electrical Power Systems.
Heat Output
The recuperated MicroTurbine can produce up to 612,000 kJ (580,000 Btu) per hour of
clean, usable exhaust heat in the range of 232 to 330 °C (450 to 630 °F).
The MicroTurbine exhaust outlet connection is 305 mm (12 in) in diameter, flowing up to
28 m
3
(2600 scf) per minute.
