Description of BS Online Uninterrupted Power Supply (UPS):
The Online UPS is suitable for environments where electrical isolation is necessary or for equipment that is very sensitive to power fluctuations.
In an Online UPS, the batteries are always connected to the inverter, so that no power transfer switches are necessary.
An uninterruptible power supply (UPS), also known as a battery back-up, is a kind of widely used electric power supply device.
Features of BS Online Uninterrupted Power Supply (UPS):
(1) Our battery back-up has a wide input voltage range
(2) The UPS can start up without battery
(3) Cold start
(4) Low impact on the mains supply
(5) Automatic battery charging in UPS off mode
(6) Lightning and surge protection function
(7) Short circuit and overload protection
(8) Fan speed auto control when loads varies
(9) Network/fax/modem surge protection
(10) LED/LCD display(optional)
(11) EMI/RFI noise filter is equipped in the electric power supply device
(12) Smart RS232 communication with monitoring software
(13) Filtered, stable and regulated-double conversion on-line(VFI) technology in accordance with EN50091-3, a with EMI filters
(14) Guaranteed output quality even with typical distorting IT loads with crest factors of 3:1
