POWER CONTROL PWM 9-28V DC 10A for motors, heaters and LEDs

MANUAL | INSTALLATION WARNINGS

This device allows you to control the power supplied by light bulbs (filament or halogen), LED lights limited to resistance such as LED strips and low voltage spotlights, motor speed (drills, fans ... etc), electric heaters via a potentiometer. with knob supplied.

The maximum load is 10A continuous on 9-28V DC with the device installed on the heatsink not supplied, otherwise without the heatsink it is possible to use the device with a maximum load of 5A. The device is ideal for resistive and inductive loads.

Thanks to PWM modulation, the module allows complete control of the power and is particularly suitable for electric motors thanks to the ability to use them even at the minimum number of revolutions. Furthermore the PWM modulation allows a very high efficiency as well as very low dissipation of the control module,

The knob potentiometer supplied allows direct control via the knob of the 95% power.

The device, excluding the potentiometer, is installed in a plastic container with an aluminum rear part that can be installed on a heat sink or metal casing.

The module can also be controlled, in place of the potentiometer, even with an analog voltage from 0 to 5V supplied by external electronic circuits.

SPECIFICATIONS:

• Input voltage: 9-28V DC

• Maximum allowed current and load: 10A (if installed on a suitable heatsink not supplied)

• Without heatsink maximum current 5A

• Power control supplied by means of a linear rotary knob potentiometer installed on a wire connected to the device via faston. Possibility of external electronic controls with 0-5V DC analog voltage

• Power control through PWM pulse modulation with 10-20kHz frequency

• For resistive ohmic and inductive direct current loads

• Connection: 2 faston for potentiometer connection (supplied), 2 faston connection in series with load for power control

• Ideal for bulbs (filament or halogen), limited resistance LED lights such as LED strips and low voltage spotlights, DC motor speed control (drills, fans ... etc), electric heaters.

• Dimensions approx. 87 x 60 x 33 mm

INSTALLATION WARNINGS

Depending on the load the module heats up. Heat is dissipated by the aluminum plate at the bottom of the module. Under certain circumstances it must be mounted on a cooling surface according to the installation instructions. It is important that the module is fixed with 4 M3 screws (or 2.9mm metal screws) on the cooling surface. This can be the back wall of a metal enclosure. The aluminum plate on the bottom of the module must not bend, do not use larger screws, and do not drill larger holes. The screw heads must rest on the module plate, instead of the plastic edge of the module! During assembly, the module must not be curled up (if the ground is not flat). The reason: inside the aluminum base of the module the thin insulation layer is directly soldered on the SMD electronic components. Make sure that the maximum expected temperature (as specified in the module description) is not exceeded. If not, apply a larger cooling plate.
