Product Description

DC TO AC inverter

Introduction
Our pure sine wave inverter is a dedicated power supply of a new generation of electric power and communication systems, we design and manufacture the inverter power supply according to the characteristics and requirements of the electric system, suitable for power system of power supply equipment high quality, high reliability requirements, are widely used in power system communication, carrier, monitoring, relay protection and emergency lighting. The power supply uses advanced sinusoidal pulse width modulation (SPWM) technology, the main circuit of Germany's Siemens IGBT module drive protection for Japan's Mitsubishi thick film circuit, with the advantages of high reliability, protection and full-featured, small waveform distortion, larger power and so on.
 

production features
(1) The main circuit adopts the United States INTEL microprocessor, Germany Siemens IGBT module, drive protection adopts Japan Mitsubishi movement, output partial adopts isolation transformer, safe and reliable
(2) SPWM pulse width modulation technology, the output is inverter, pure sine wave of low distortion
(3) Full-bridge circuit structure, applicable to any load
(4) DC input uses state-of-the-art anti-filling noise suppression technology, the AC input of multiple filtering to eliminate the interference of the electricity grid, communication equipment and other common DC panel without disturbing each other
(5) With a full range of power protection solutions and perfect self-detection and protection. DC input voltage is too low alarm, overload alarm, overheating alarm and short-circuit, the power will turn off the inverter output, troubleshooting, manually reset the power to work properly; Input under-voltage protection fault is cleared after the output will automatically resume
(6) Compact circuit structure, high efficiency, strong function
(7) Group-screen installation, elegant appearance

Adapt to the environment
1. For desolate area like mountain, island, pasturing area, etc.
2. For transportation system like beacon light, traffic light, street light, etc.
3. For communication system: unattached operation microwave middle   station, optical
cable maintenance station, etc.
4. For photovoltaic power station, wind-solar power station, park charging station, family
   power house, factory power station, etc.
5. For solar building: has good business future.
6. For the new technology application project.
