Static Bypass Industrial UPS Power Supply Strong Transformer 384VDC

High-reliability Design:

CONSNANT Company apply herself to the development of China’s electricity demands for power plants, substations, power distribution products are designed with online double conversion, zero conversion function. The CNI330 system is composed of power special-purpose UPS, DBW regulator cabinet, PDU series feeder cabinet. Main applications including electric power long distance, RTU, power carrier wave, power monitoring and so on. When the utility power is normal, single phase 220V(or three phase 380V.) After isolation, rectification and filtering through the inverter to provide a stable power supply to the load; if the input AC power is abnormal or power failure, the backup power system by the DC screen provide power through non-return diode inverter. When the DC screen occurs voltage shortage or power break, the static switch transfer to bypass for power supply; when the electricity is restored, the inverter automatically switches to utility power and provide power supply under inverter mode. If the inverter overload or fault and transfer power supply under bypass mode, also give a warning signal at the same time.

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:

Microprocessor bus control technology, three-core processor rectifier, inverting and parallel

Rectifier:

6 pulse or 12 pulse fully controlled bridge (6 or 12 SCR) compose rectifier.

Inverter:

SPWM(sinusoidal pulse width modulation) , formed by 6 IBGT high power tubes, is composed of full-bridge-control. 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.
