Product Description

Product Description

Constant current source:

Technical characteristics:
1. AC constant current source is specially designed and manufactured for low-voltage electrical appliance users. Its output current is constant, and its output waveform is pure sine wave. It can carry resistive, inductive and capacitive loads, meet the requirements of low-voltage electrical appliances for test power supply, and can be used as an over-current test instrument.
2. Outstanding advantages, high current stabilization accuracy, can be used according to the user's environment. Ensure constant output current.
3. Automatic test of different current levels can be carried out (items: voltage, current, frequency, lifting time, and cyclic test operation)
4. Frequency adjustable range: 40-500HZ (optional), fixed output: 50HZ, 60HZ (fixed output frequency within more ranges can be designed according to user requirements)

 

Product application:
1 AC air switch
2 AC contactor
3 Mechanical switch and electronic switch
4 Cable and wire
5 Automatic detection and calibration platform
6 Large current capacitor electrical appliances
7 Thermal relay, molded case circuit breaker, small circuit breaker and the required rated current, action current, short-circuit protection current, etc

FAQ

1. Q:  Does installation Easy ?

    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.
