SNR UPS-ONT-010-BXL31 [10/34] Ups working mode

Product Description

High Performance 10-20k UPS

1.5.4 Battery Charger

The battery charger utilizes energy from the DC bus and precisely regulates it to continuously charge

the batteries. The batteries are being charged whenever the UPS is connected to utility power.

1.5.5 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.

1.5.6 Battery

The 10K/20K Standard include value-regulated, non-spillable, lead acid batteries inside. To maintain

battery design life, operate the UPS in an ambient temperature of 15-25C.

1.5.7 Static 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 once.

NOTICE：The bypass power path does NOT protect the connected equipment from disturbances in

the utility supply.
