H-bridge - Another one from ebay

[denyszandonadi]

Does anyone tested this H-bridges? This look well designed for me, but i cant find anything on internet that talk about this product.
The first can handle 100A and the second 60A.


Thank you for any answer!

Datasheet and pinout!

Sorry, my bad!

The only information i have is this one:

1, the basic components of the drive module body placement, highly integrated, well-designed board layout, very beautiful, very small, onboard two-way high-power DC motor drive, the drive module size of only 70mm * 56mm;

2, large heat sink at high currents can effectively drive module for cooling, maintain good and stable performance of the module;

3, when the drive motor, the module maximum rated current up to 60A, and conduction only 0.003 ohm resistor;

4, the switching frequency is high, the most up to 60KHZ, thus effectively avoiding the low frequency of commissioning motor brings unpleasant;

5, the control interface is very simple: A1.A2 = 0.0 when the brakes; when A1.A2 = 1.0 for forward; A1.A2 = 0.1 when reversing; PA for PWM wave input (motor speed adjustment); G for the Dashboard common ground pin (B road for the same control);


6.3.3V/5V compatible, and only need 1 channel motor power supply 12~30V

This is the link for 60A:

Thank you!

If you read the datasheets of the IC's mounted on this bridges you get the info that 60A is only for short usage.
This means this bridge can handle about 30-40A effective and if you use a bigger heatsink or fan.
So you must find a picture or info about the used MOSFETs on this board to be sure.

The bridge has all pinouts for usage with Arduino XPID firmware.

By the way, if you do not buy a complete controler with bridge, you should buy some more bridges, else you may burn one and then wait for the spare part.
