connected to utility power.
3.5 DC-to-DC Converter
The DC-to-DC converter utilizes energy from the battery system and raises the DC voltage to
the optimum operating voltage for the inverter. The converter includes boost circuit which is
also used as PFC.
3.6 Battery
The standard model include value-regulated, non-spillable, lead acid batteries inside. To
maintain battery design life, operate the UPS in an ambient temperature of 14-25°C.
3.7 Dynamic Bypass
The UPS provides an alternate path for utility power to the connected load in the unlikely event
of a UPS malfunction. Should the UPS have an overload, over temperature or any other failure
condition, the UPS automatically transfers the connected load to bypass. Bypass operation is
indicated by an audible alarm and illuminated amber Bypass LED.
NOTICE：The bypass power path does NOT protect the connected equipment from
disturbances in the utility supply.
