PWM POWER CONTROL KEMO M195 9-28V/DC, MAX. 20A
Power controller for controlling DC loads (DC motors, light bulbs, heaters, LEDs with current limiting resistors, etc.) The use of PWM (pulse width) control works well even with electric motors running at low RPM. Switching frequency: approx. 300 - 600 Hz (for motors, a humming noise may be heard). The control is via the supplied potentiometer or optional with an external control voltage 0 to 5 V/DC.
The module may heat depending on the load. Therefore, it has to be mounted in a dry and well ventilated place. In case of loads of more than 5 A (up to max. 20 A) the module with the metallic base area has to be cooled. This is done by attaching it planely on a heat sink or bigger metallic piece in such a manner that the module will not heat to more than +70°C under highest load.
The operating voltage of the module must be between 9 - 28 V and come up to the operating voltage of the connected load.
The capacity of the module is max. 20 A! Please make sure that the connected loads do not have a higher current consumption! There are motors, which have a current consumption of e.g. 8 A during operation but require >30 A during the start-up or in blocked condition! These will destroy the controller.
