Primary Functions and Characteristics
1
．
Intelligentized RS232 communication function: With RS232 standard
data interface and UPS power management software, realize three
remote-control functions between computer and UPS, computer
supervises UPS operation and electric parameters, and realize
long-distance power on/off function, as well as supporting SNMP
network adaptor (outlaid, connecting UPS through RS232 interface),
which enables UPS to directly become network fresh blood.
2
．
High input power factor: Adopt advanced active PFC technique, which
alleviates load on electric network and represents green power supply of
new generation.
3
．
High performance-price ratio: Adopts multiple power transfer and high
frequency PWM technique, high efficiency, small size and light weight as
well as improving operational reliability and reducing manufacturing cost,
which lowers the cost of the system design for customers.
4
．
Perfect protection function: Possess such functions as output
low-voltage protection, battery low-voltage protection, input low-voltage
protection and triple overflowing protection, etc and overcome previous
defects such as high frequency UPS' poor adaptability and weak
resistance to shock for electric network.
5
．
Low commercial power input voltage: Adopt independent quick detection
technique, even at the lower limit 140V of commercial power, the battery
remains off discharge, thus all energy output are taken from electric
network, ensuring the battery in the state with 100% energy storage,
while at the same time decreasing the battery discharge times and
prolonging its life.

Precautions
Abide by the following general safety precaution during operation or
maintenance.
