AND220 series dedicated power line frequency inverter

(Introduction)

AND line frequency inverter for power plants, substations and high reliability requirements of the power supply to the new technology developed intelligent frequency inverter, the system uses SPWM pulse width modulation technology, IGBT module and output isolation transformer, the output inverter frequency stabilization for a regulator, filter noise, interference from power fluctuations. low distortion pure sine wave power supply with load capacity, load compatibility, DC input voltage range width and other characteristics, to meet the great demand for various electrical environments, and improve protection device to improve system stability and reliability; humanity was the LCD interface design, makes machines to communicate zero distance, inverters and between the PC can communicate via RS232 communication interface, allowing users to easily work on the terminal at any time to observe the situation, history inverter, timely inverter control.
(Features)

• Efficient IGBT inverter technology

IGBT has a good high-speed switching; the operating characteristics of high voltage and high current; voltage-type drive; only a very small control power; high efficiency (low loss and low heat), the drive circuit miniaturization, high reliability.

• Superior load characteristics:

Fully meet the transition from 0-100% load; to provide instant full-load requirements; and having to switch to bypass; and keep the output stable and reliable;

• to allow 100% unbalanced work:

• three-phase modulation independent, full-bridge inverter technology, three-phase unbalanced load 100% can be normal and reliable power supply.

• input and output using frequency isolation transformer isolation, has EMI suppression.

• using electricity standard cubicle designs.

• Colors can be based on user requirements.

• Internal installation backstop diode

DC-DC bus between the input side and connected via blocking diode prevents the DC bus voltage is higher than the DC input side of the high voltage to a DC-screen anti-irrigation, played the role of DC-screen protection.
