PWM950 Module is designed to enable the user to vary the voltage across a solenoid or other devices. The Pulse Width Modulation (PWM) is proportional to the input control voltage. The maximum pulse width could be adjusted using an onboard trim potentiometer. To apply the control voltage, a DC power supply could be used. This is particularly useful when a solenoid requiring a relatively large amount of power needs to be turned on and off with a low power trigger voltage such as a TTL compatible signal. |
