Product Description

Product Description

This series products adopt high frequency electronic switch changing technology,design and manufacture for air and military electrical equipment of 28.5V DC switch power,it a product instead of thyristor-controlled DC Source.
Application:   
It can be used in aircraft and on-board equipment, radar, navigation and other electronic equipment military,and other needs 28.5V or 24V DC power supply field.And for all panzer and tanks, planes, guns, the power to start using.

 

Performance characteristics
★Power devices using a new generation of IGBT,use of IGBT switching mode high-frequency low-loss characteristics,complete  energy conversion, with a small size, light weight, high efficiency, high reliability
★Current-mode control with full-bridge conversion, PWM control, and slope compensation technique, without anti-bias magnetic capacitors in series, with fast dynamic response, shock load capability, the advantages of a reliable over-current protection
 

★Intelligent monitoring using micro-chip computer to complete the power of intelligent control, LED / LCD panel display power supply operation parameters and working conditions; with a self-diagnostic features ,can remember the recent failures, improve maintainability
 ★Functional units and components, all designed to be modular structure, via the components of series expansion, small size, high efficiency, reliability and good maintainability
★Machine with 19 "standard chassis structure, either alone or rack can be installed

    A: Very easy, every customer can do it by themselves, we will supply all the components for installation and very                 details installation manual. 
 

2. Q:  Does our wind is enough for a wind generator ?

     A:  As our wind generator can start running at low wind speed2.5m/s. so your average annual wind speed is more               than 5m/s then you can use it .
 

3. Q:  Which model of wind generator is suitable for me?

    A: Please contact our sales with following points :

       (1) What appliance do you want to running by the system?  How many watts are they and their working time .

       (2)Your annual wind speed .

       (3)What kinds of system do you want ? On-grid or off-grid
 

4. Q:  Can I only buy parts not whole system?

    A: Yes, for example you can manufacture tower on local , we can supply you tower drawing.
 

5.  Q:  For horizontal axis wind turbines VS vertical axis wind turbines, which kind of efficiency is better.

     A:  For same model at same wind speed, the output of horizontal axis wind turbines is more efficient than that of                  vertical axis wind turbines.
