Application
Our outdoor UPS CNW330 series is specially designed for telecommunication base stations.Whether it is used in remote sites or urban networks, our professional team can design solutions for various application scenarios, whether outdoor or indoor, to ensure the smooth operation of power equipment.
System Layout Diagram:
The UPS consists of the following blocks:
RECTIFIER
Converts the input AC power to DC power, The functions are the following:
– Powering the inverter with direct current.
– Charging the battery automatically. Float charge to 80% first, then equalized charge at a constant voltage.
The charging current is limited to 15% of the battery Ah value (stored in memory!) This charging current will only be executed when the total output does not exceed 110% of the rated value.
EXTERNAL BATTERY
Provides the reserved energy for powering the load when there is no power input to the UPS.
HARMONIC REDUCTION FILTER (optional)
The filter, in the front stage of rectifier, reduces harmonic distortion of input current. It consists of two inductors and several capacitors, and is protected by a fuse.
INVERTER
Converts the DC power of a rectifier or battery into AC power. It remains in working condition at all times to provide power to the load.
STATIC SWITCH
Allows to automatically or manually switch between INVERTER output and BY-PASS bypass output in real-time.
At the same time, this static switch has a “Backfeed Protection” device to prevent current feedback caused by abnormal SCR faults.
SWMB
Turn on the SWMB switch and turn off other switches SWIN, SWBY, or SWOUT, the UPS will be isolated for maintenance purposes. At this point, the load can still obtain power without being affected, because there is no voltage inside the UPS (The voltage only exists in the input/output terminal block and switch section. But on UPS with three-phase output, the neutral line is not separated!).
