Key Features:

• APS Outdoor Intelligent High Frequency Online UPS provide continuous pure sine wave AC power supply for outside communications / network equipment.
• Double-conversion online design, high temperature resistant, anti-cold, sealing level for IP55; with the wide range of input voltage and frequency of input window 45% +35% rated voltage and ± 10% rated frequency), in many remote areas of China after a severe test of the grid.

Application

This UPS is commonly used in the corner of the city, remote roads, mountains, bad environment, such as high temperature (+50 °C) / low temperature (-40 °C), severe dust, moisture, rain, mist erosion, very poor power quality (voltage longterm higher than 260V or less than 160V, frequency abnormal change) in the area.

High Reliability of the UPS System

• Using microprocessor control, directly produce high frequency pulse width modulation wave (SPWM) control of the UPS inverter, to simplify the UPS control circuit, to improve the stability, to have more real-time UPS to quickly respond to changes in the external environment and guarantee the machine’s control circuit is more simple and reliable.
• Using digital control techniques, to avoid the traditional analog control temperature drift inherent defects such as hardware parameters, to ensure consistency and reliability of UPS.
