2.3 Features
Intelligent RS232 and USB communication
Through RS232 or USB standard data port and UPS power management software, it can realize the
three remote function between the computer and UPS, monitor the running and electrical data of UPS
on the computer, perform ON/OFF operation remotely and support SNMP network adaptor (external,
connect with UPS through RS232), which makes UPS be a network new member.
High input power factor
UPS adopts the advanced active PFC technology, which eases load in the power grid. It is the new
generation green power.
High cost performance
UPS adopts many kinds of power conversations and high frequency PWM technologies, which is
with high efficiency, small volume, light weight, improves the running reliability and reduces cost.
Perfect protection
Equipped with the functions, such as output over-voltage protection, battery under-voltage protection,
input over-voltage protection, triple over-current protection, etc. and solve the problems of the high
frequency UPS, such as poor adaptability in the power grid and weak anti-impact ability.
Low mains input voltage
Adopt the independent rapid detection technology. When the mains input voltage is 120V, which is
the lower limit, the battery still doesn't discharge. Therefore, in the mains mode, all output power gets
from the power grid, which is to ensure the battery is still in the 100% energy storage status, reduce
the battery discharge times and prolong working life.
