Hitec UPS Dual Output Design Guide
Introduction
The Dual Output Diesel UPS system is designed to replace the
traditional Standby Diesel, Static/Rotary UPS and battery configuration.
By rating the diesel engine and alternator to supply the total site
loads the system can provide the UPS requirements on a continuous basis,
while allowing the standby loads to be re-connected within a few seconds
of any Mains failure.
The Dual Output System can then effectively perform the functions of
both UPS and genset within one integrated unit, which can release the
space traditionally required for the central static/rotary UPS,
batteries, switchgear and associated air conditioning equipment. This
can represent up to 60% of the overall space
allocated for the service requirements.

Fuse Clearing Capabilities
Each Hitec Dual Output UPS Sytem has the ability to clear fuses of up
to 100% of the UPS output whilst maintaining the output voltage within
the specified tolerances.
Input Harmonics
The Hitec Dual Output Diesel system does not incorporate an input
rectifier as with static systems therefore the reflected harmonics onto
the mains utility are negligible and within the requirements outlined in
the Electricity Association’s regulations G5/4.
Load Harmonics
The Hitec Dual Output Diesel system is a low impedance source and is
therefore able to supply non linear loads without de-rating or the
addition of filters.
