Electricity UPS System Special Cabinet Electricity UPS 10-100KVA
 
 
 
 
Key features:

1. Adopt full digital control technology
2. Intelligent detection and monitoring function
3. Digitally control the static switch with zero switch
4. Full isolation between input and output
5. Super low output zero earth voltage
6. DC UPS isolated with utility power completely
7. Cubical design with power standard (customization)
8. Multifunctional protection for overvoltage, under voltage, over current, short circuit and over temperature and so on.
9. Large-screen LCD monitor with Chinese and English operation interface
10. Ultralong 256 event record, user-friendly analysis and management to the situation of the power supply (touch screen optional)
11. Static bypass has a strong anti-overload capability

 
Application:
Petroleum, chemical industry, gas and power station and so on.
 
 
 
Control system:
It adopts microprocessor bus control technology, three core processor controlling rectification, inversion and parallel connection respectively, to ensure the real-time control of the rectifier, inverter and static switch and the coordination of every power part, characterized by increased control of aging, higher reliability, enhance of the efficiency of the whole UPS system and the output technical parameters are better than that of the device with same capacity.
 
Rectifier:
6 pulse or 12 pulse fully controlled bridge (6 or 12 SCR) compose rectifier. Its function is to input AC 3880V to DC220V or so by rectification. “slope” start (soft start) is the control feature, which means output voltage of the rectifier increase from 0V to 220V within 10 second and has no impact on the power grid.
 
Inverter:
SPWM(sinusoidal pulse width modulation) , formed by 6 IBGT high power tubes, is composed of full-bridge-control.
Large Capacity of Overload of the UPS Inverter
110% load --60＇
125% load --10＇
150% load --1＇
200% single phase load --30＂
Good Capacity of Resistance to Output Short Circuit Current Limiting and Period Load Impact
 
 
 
Static switch:
 

• Not sync automatically switch
• Optional bypass cabinet: Isolating transformer and the bypass voltage regulation
• Intelligent monitoring:Working status and data of UPS are transmitted to DCS system in real-time via RS232/RS485, passive contact and power transmitter, which finally realize Intelligent monitoring.

Unique option:
 

• SNMP card
• Dry contact card
• Signal transmitter
• Bypass isolation and voltage regulation
• Increase feeder circuit (standard for 8 loops)
• 12 pulse rectifier
• The appearance of special models(standard dimension:800×600×2260mm)
