Technical Data:

1 Working voltage: DC 12/24V

2 Rating current: 8A(12V); 4A(24V)

3 Size: Refer to drawing. Roller or rachides

4 Function: This variable speed controller can control the resistor to adjust the air flow arbitrarily in the air flow volume.

12/24V is same with the resistor, no need to add other parts. we can do the roller as customer’s requirements.

5 Material of case: black ABS

6 red, black, blue and yellow wire ,30cm

7 Applied for heater. Heater variable speed controller.
