Manson N2097, VWM-4108 User manual

Hello! I've reviewed the user manual for the Manson PWM Controller VWM-4108. This device is a 12VDC 8A PWM controller for efficiently dimming lights and controlling the speed of DC motors. The document also covers installation and operation details. I am ready to help with your questions about this device.
What is the main use of this PWM controller?

What type of power source do I need?

How does it control the output?

PWM Controller of DC Motor & Light

User Manual

Introduction

This 12VDC 8A pulse width modulator (PWM) is a general purpose DC output power control. It can

be used as an efficient light dimmer, DC motor speed controller such as small dc fan, pump

controller. By varying the pulse on-off ratio the average on time is also varied from 0-100 percent.

The main advantage over the conventional resistor controller is it consumes much less power and it

is much cooler than a resistor controller. In motor application it generates more torque and start the

motor more easily.

Installation

1. Install the controller as close as possible to the output load.

2. Double check Input and Output polarity before connecting to a Nominal 12VDC source such as

12V battery.

3. Turn the volume knob to Min position before connection to DC load.

4. Turn the knob gradually to near Max to check variable speed or light.
