• 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
 
 
Advantages:

290% rated current -- 5＂: Even though a output short circuit or an overload occurs because of user’s improper operation, the output current of UPS can still be limited to a controllable extent instead of exceedingly increasing, consequently laying a good foundation for a long-term and reliable operation of UPS.
 
 
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:

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)
