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. Technical

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.
