2.3System Operation

The UPS shall operate as an on-line, fully automatic system in the following modes:

A. NORMAL - Incoming AC power is boosted using a chopper circuit,

and converted into DC power. The DC power is then used to charge the battery bank while at the same time providing clean, DC power to the inverter circuitry. The inverter converts DC power to regulated AC power which feeds the load.

B. EMERGENCY - Upon failure of commercial AC power, the UPS shall derive power from the battery bank and continue feeding the load with clean, regulated AC power. There is no interruption to the critical load upon failure or restoration of commercial AC power.

C. RECHARGE - Upon restoration of the commercial AC source, the rectifier/chopper powers the inverter while simultaneously recharging the battery bank. The UPS shall have the following recharge process:

a)a constant level of current is used to recharge the batteries (the process shall utilize a current-limit function to prevent overcharging batteries, thus extending the life of the batteries)

b)as the batteries reach the normal charge level, a constant-voltage control shall begin which causes the battery recharge current to gradually decrease

c)Under normal operation, the UPS battery bank "floats" at the 2.25-2.27 volts per cell DC level to stay fully charged and ready for the next discharge.

D. BYPASS MODE - Upon detection of an internal fault or output overload, the UPS shall automatically switch from inverter power to an internal bypass via the static switch. Transfer shall be within 4 milliseconds, causing no interruption to the critical load. While in bypass, the UPS shall protect against spikes and common/normal mode noise by utilizing a dual-winding output isolation transformer. “Return from Bypass mode” shall be an automatic function, without interruption to the critical load. Transfer to Bypass may also be performed as a manual operation via the UPS front panel.

E. POWER CONDITIONING MODE - Should the batteries be removed from the UPS, the UPS shall continue to function and still provide
