1.3         SYSTEM DESCRIPTION

1.3.1    Modes of Operation

The UPS shall be designed to operate as a true on-line double-conversion system in the following modes:

A.     Normal - In normal operation incoming AC power shall be fed to the input power factor corrected (PFC) rectifier that converts the AC power to DC power for the inverter. In this mode, power shall also be derived from utility power for the battery charger. The inverter shall derive DC power from the PFC rectifier to regenerate filtered and regulated AC sinewave power for the connected load. The unit shall begin charging the battery once the UPS is connected to utility power, regardless of whether the UPS is ON or OFF. In the event of a utility outage or severe abnormality (sag or swell), the inverter shall support the connected load from battery power until the battery is discharged or the utility power returns, whichever occurs first.

B.      Battery - Upon failure of utility / mains AC power, the critical AC load shall be supplied by the inverter, which obtains power from the battery. There shall be no interruption in power to the critical load upon failure or restoration of the utility / mains AC source.

C.     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 the battery charger to recharge the battery.

D.     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.

E.      Bypass - The integral bypass shall perform an automatic transfer of the critical AC load from the inverter to the bypass source, in the event of an overload, PFC failure, internal over temperature, DC bus overvoltage or inverter failure conditions.

F.      ECO – The UPS shall allow the user to enable and place the UPS in ECO mode of operation to reduce electrical consumption.  The ECO mode operation shall be an Active type, whereas the UPS will power the connected equipment through the bypass path and the UPS inverter shall be on and operating at no load in order to stay synchronized to the bypass to ensure rapid transfers to inverter power when input power falls outside of the user customizable parameters.  The UPS shall also have a user customizable requalification time that input power must remain within the ECO mode parameters before transferring back to ECO operation.  This is to minimize the number of transfers between bypass and inverter.

 

1.3.2    Design Requirements

A. Voltage

Input/output voltage specifications of the UPS shall be:

Input

·         120V units:     0 - 140VAC, 50/60Hz, single-phase, 2-wire-plus-ground.

·         208V units:     0 - 280VAC, 50/60Hz, single-phase, 2-wire-plus-ground.

·         230V units:     0 - 280VAC, 50/60Hz, single-phase, 2-wire-plus-earth.

Output

·         120V units:     120VAC (user configurable: 110V, 115V, 120V, 127V) ±3%, 50/60Hz, single-phase, 2‑wire-plus-ground.

·         208V units:     208VAC (user configurable: 208V, 220V, 230V, 240V) ±3%, 50/60Hz, single-phase, 2‑wire‑plus-ground.
