The PWM functionality is managed in two different ways:
The Outputs LMH may manage a 100 HZ PWM
The Half Bridge High Power Outputs may manage
configurable frequency PWM from 1 Hz to 10 KHz.
To configure a PWM output, with the duty cycle
depending upon some conditions, please:
• Set the Power Output as PWM
• Define the logics that manage the
different duty cycles
In this example, we correlate the duty cycle of the Power Output FAN to the Water temperature:
In the range 70°C – 80°C the duty cycle is 10%
In the range 80°C – 90°C the duty cycle is 50%
If the water temperature is higher than 90°C, the duty cycle is 100%.
The time for passing from one level to the next one is set at 5 seconds.
The Duty Cycle in a PWM Output is the ratio
between ON and ON+OFF status of the
output. The higher is the ratio, the higher is
the energy that the output gives. If you
connect a lamp or a fan to a PWM output,
you may, changing the duty cycle, change
the brightness (of the lamp) or the speed (of
the fan).
