The PWM400 Module is designed to enable the user to convert the input voltage in order to apply a different voltage to the solenoid or coil. The output voltage to the coil can be varied to within 5% to 85% of the input voltage by adjusting an on board trim potentiometer. The voltage within the above range can then be applied to the coil when a voltage (2 to 40 VDC) is applied to the trigger. 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 signal. |
