3.4 Battery Charger
The battery charger utilizes energy from the utility power and precisely regulates it to
continuously float charge the batteries. The batteries are being charged whenever the UPS
is 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 6K/10K Standard include value-regulated, non-spoilable, lead acid batteries inside.
To maintain battery design life, operate the UPS in an ambient temperature of 15-25°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. To
manually transfer the connected load from the inverter to bypass, press the ON/OFF button
or Manual Bypass button once.
NOTICE： The bypass power path does NOT protect the connected equipment from
disturbances in the utility supply.
