PART 1GENERAL

1.1SUMMARY

1.2This specification shall define the electrical characteristic, mechanical characteristics and design requirements for a single-phase, solid-state uninterruptible power supply (UPS). The UPS shall provide continuous AC power for critical electronic equipment loads.

1.3REFERENCE STANDARDS

The UPS system defined within this specification shall be designed and manufactured according to latest revision of the following standards. Where a conflict arises between these documents and statements made herein, the statements in this specification shall prevail.

A.UL Standard 1778, 4th Edition; and c-UL Listed

B.CSA 22.2 No. 107.1

C.NEMA Type 1 Enclosure

D.FCC Part 15, Class B

E.IEC 61000-3-2

F.ANSI C62.41, Category A

G.ANSI/NFPA 70

H.EN62040-2

1.4SYSTEM DESCRIPTION

A.The UPS shall be designed to operate as a true on-line double-conversion, voltage and frequency independent (VFI) system in the following modes:

1.NORMAL - Under normal input conditions energy from the mains shall be channeled through the input converter, which supplies the output converter and, together with the battery charger, keeps the battery fully charged. Surges and spikes shall be blocked completely at the input converter and very unstable mains can be supported. The output converter synthesizes a completely new AC output sine wave to supply the load (electrical equipment).

2.ON-BATTERY - In the event of a mains power failure (i.e. mains absent or outside tolerance) the output converter uses the energy reserve stored in the battery to continue to produce AC power, ensuring unbroken output. No interruption or alteration shall ever be noticed in the output power. In the event of an extended mains failure, the output converter shall stop when the battery energy has been used up. At this point, the UPS is no longer able to power the connected equipment. When the mains voltage is re-established within tolerance, the input converter shall be supplied again by the mains and the batteries shall be recharged, making them ready to support future power failures.

3.RECHARGE - Upon restoration of utility / mains AC power, after a utility / mains AC power outage, the input converter shall automatically restart and resume supplying power to the inverter and to the battery charger to recharge the battery.

4.INTERNAL BYPASS - If the output converter is unable to deliver the demanded output power (overload, over temperature) the bypass switch shall automatically transfer the load to the mains. If bypass operation is caused by an overload situation, the UPS shall try to switch back to output converter after 0.1 seconds, without generating any alarm. This way bypass alarms due to inrush currents, which normally last less than 0.1 seconds, shall be avoided. If the overload situation still exists after three switch-back attempts (i.e. the overload is not caused by inrush currents), the unit shall remain in bypass mode, generating a bypass alarm. The unit shall switch back to output converter when the overload has been removed. If bypass operation is caused by over temperature, the unit shall switch back when the temperature has dropped below alarm level. When the normal situation is restored, the load shall be transferred back to the output converter.

5.AUTOMATIC RESTART - Upon restoration of utility / mains AC power, after a utility/mains AC power outage and complete battery discharge, the UPS shall automatically restart and resume supplying power to the critical load and the battery charger automatically recharges the battery. This feature shall be capable of being disabled by the user.
