battery operation and retransfers from battery to normal operation.
C.
Recharge: Upon restoration of the AC input source, the input converter and output
inverter shall simultaneously recharge the battery and provide regulated power to the
critical load.
D.
Automatic Bypass: The automatic bypass shall be used to provide transfer of critical
load from the Inverter output to the bypass source. This transfer, along with its
retransfer, shall take place with no power interruption to the critical load. In the event of
an emergency, this transfer shall be an automatic function.
E.
Manuel Bypass: The system shall be equipped with an internal make-before-break two
pole switch to electrically isolate the UPS from the input and output during preventative
maintenance, module upgrades, or limited frame service. The manual bypass shall also

the power modules (recitifier, battery charger, inverter) , and battery modules in the
same manner as the automatic bypass will still supplying surge and EMI filtering, and
overcurrent protection. There will be a positional sense supplied to alert users that the

AUTOMATIC BYPASS
A.
As part of the UPS, a system automatic bypass switch shall be provided. The system
automatic bypass shall provide a break <11Ms transfer of the critical load from the
Inverter output to the automatic bypass input source during times where maintenance is
required, or the inverter can not support the critical bus. . Such times may be due to
prolonged or severe overloads, or UPS failure. The additional manual bypass switch
will have a no break transfer of critical loads from Inverter output to the manual bypass
switch which will correspondingly engage the automatic bypass switch driving it into
bypass position. The UPS shall constantly monitor the output current, as well as the
bypass source voltage, and inhibit potentially unsuccessful transfers to automatic
bypass from taking place.
B.
The design of the automatic bypass switch power path shall consist of a heavy duty
electromechanical bypass contactor with a continuous duty rating up to 100A.
C.
Automatic Transfers: An automatic transfer of load to bypass shall take place
whenever the load on the critical bus exceeds the overload rating of the UPS. Automatic
transfers of the critical load from bypass back to normal operation shall take place when
the overload condition is removed from the critical bus output of the system. Automatic
transfers of load to bypass shall also take place if for any reason the UPS cannot support
the critical bus.

through the UPS display interface or by engaging the manual bypass switch on the front
of the unit.

current from magnetic devices, or short circuit conditions, the automatic bypass shall be
capable of sustaining overloads of 1000% of system capacity for sub cycle fault
clearing.
