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 ups L include value-regulated, non-spoilable, lead acid batteries outside. To maintain
battery design life, operate the UPS in an ambient temperature of 15-25
°
C.
3.7 Dynamic Bypass
The ups provide 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.
NOTE
：
The bypass power path does NOT protect the connected equipment from disturbances
in the utility supply.
