4 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

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

overvoltage protection, battery undervoltage protection, input

overvoltage 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 160V 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.

5 Precautions

Abide by the following general safety precaution during operation or

maintenance.

1 Please don't remove the cover. This system can only be maintained or

repaired by professional maintenance personnel.

2 Protective ground terminals should be connected to earth end for sure.
