Power Plant Electricity UPS System Digital Control Output PF 0.8

10 - 100KVA​

Application:
Petroleum, chemical industry, gas and power station and so on.


Key features:

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

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. Its function is to transform DC voltage into sinusoidal AC voltage, boosting by the special (△/Y) zero phase shift zigzag type isolation transformer and become AC220V as load required. In addition, the transformer can eliminate like triple harmonics current that are reflected by non linear load from computer. Control features is the adoption of the “slow-down gate voltage” protection technology, greatly reducing disturbance of shutoff of the inverter (inverter and static switch shift mutually ), enhancing the overload capacity of the whole UPS system, which make the capability of anti-short circuit and anti overload of UPS far superior to the ordinary UPS, especially the anti shot circuit is unmatched by similar devices.

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:

• When the bypass of the UPS lose sync with the inverter, system can automatically implement not sync switch, for example, when the utility power surge pulse width <5ms, the system can ensure no power cutoff.
• When the bypass exceed the limitation, UPS will detect the bypass every 20ms, when the phase angle difference of bypass and the inverter turn to normal range, not synchronized bypass shifting can be realized.

Optional bypass cabinet:
Isolating transformer and the bypass voltage regulation

Intelligent monitoring:
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)​
