ups power, modular ups manufacturer

Ideal Application
Our outdoor ups is widely used for base station for mobile communications, small telephone exchange, various kinds of outdoor IT equipments.

Introduction
Outdoor UPS is a high performance, small power rating UPS developed by EAST with its rich experience in developing and manufacturing UPS for the PHS system in telecommunication network. This outdoor ups has a simple structure and an integration of rain-proof, burglar proof, dust-proof and lightning-proof functions. Wall type or vertical type cabinet structure makes it easier to be installed and maintained. It has excellent performance and reliability, and it also has comprehensive automatic protection functions to provide clean and steady uninterruptible power supply for the PHS system.
When the commercial power is in regular conditions, single phase or three phases input will be filtered, peak-surge absorbed and stabilized to provide power for PHS system. When the commercial power failed or there is a power-off, the UPS will use the backup battery to provide power through the inverter circuit. When the power-off lasts too long, the UPS will keep working on the DC to AC inverter mode until the battery voltage becomes too low and reaches under-voltage protection. The UPS will automatically turn itself on when the commercial power recovers to regular conditions, and this does not need any human interference. The large current high frequency charger inside the cabinet will shorten the battery charging time, so it can improve battery life and lengthen the service period of the machine to make sure the system can work properly. 
 
Features & Fenefits
1. Adaptability to wide range of AC power
With stabilizing function added to the UPS output, the UPS can work properly when the commercial power voltage changing between 165 volts and 275 volts.
2. Special for outdoor environment
Our outdoor ups has an integrated design of rain-proof, burglar proof, dust-proof and lightning-proof functions. Wall type or vertical type cabinet structure makes it easier to be installed and maintained.
3. Peak and surge absorption
This kind of outdoor ups can suppress the peak, surge and other instantaneous change on the power wire to prevent the PHS system from destruction.
4. Good electromagnetic compatibility
The whole machine employs advanced electromagnetic interference-proof technique to have a good electromagnetic compatibility, so it will not interfere with the equipments connected to it.
5. Battery low voltage protection and automatic charging
When the commercial power failed or there is a power-off, the UPS will use the backup battery to provide power through the inverter circuit. When the power-off lasts too long, the UPS will keep working on the DC to AC inverter mode until the battery voltage becomes too low and reaches under-voltage protection.
6. Overload protection
The machine does not turn off the output when an overload occurs, on the contrary, it turns down the output voltage according to the magnitude of overload. Once the load is regular, the output voltage will return to regular too. In this way, the power-off because of instantaneous overload will be avoided, and the equipment connected to the UPS can work as usual. 
7. Advanced wide input frequency technique
When the frequency of commercial power network departures too much, this UPS can still work properly, so it can be applied in power networks powered by various kinds of dynamos.
8. Short circuit protection
The UPS will turn off automatically, and it will not be destroyed because of load short circuit.
9. The large current high frequency charger and the even/floating charging-mode switch technique will shorten the battery charging time, so it can lengthen battery life.
10. A specialized lightning proof module will be installed as the customer requires. In areas with high lightning incidence, this function will provide more effective protection
11. Double panel design to guarantee reliability
