MASTER RETRY CHANNEL
Master Retry Channel allows user to perform reset of Power Outputs. If a Power Output has
signaled a fault, due to either over or under current condition, triggering a Master Retry will reset it
back to default state. Master Retry can be triggered by any channel or element. Master Retry
configuration can be found in Tree View → Global Output Settings → Master Retry Channel .
PWM (PULSE WIDTH MODULATION)
PMU has the ability to apply PWM to 25A Output Pins.
The main principle of Pulse Width Modulation is to limit the amount of Power supplied to Power
Output by alternating power Output on and off.
Keep in mind that PWM introduces energy loss to heat due to transistor switching on and off.
Higher frequencies generate more heat, therefore If you are experiencing overheated status on
Power Outputs or high heat in general, either lower the Frequency of PWM, or use a flyback diode
to eliminate flyback and lower the thermal load (See Using flyback diode section).
