2.6 Load protection current limit
The configurable load protection current limit provides three parameters to customize the
overcurrent protection of the load.
•
Current rating: Constant load current above this level will trip the breaker OFF.
•
Inrush Delay: An adjustable delay (0 to 1500 milliseconds) that starts at the time of
breaker turn ON. The configurable current limit trip is blocked during this period.
•
Trip Delay: An adjustable delay (0 to 750 milliseconds) that starts when currents
exceeding the current rating setting are detected after the Inrush Delay has expired.
The configurable current limit trip is blocked during this period.
2.7 Pulse Width Modulation (PWM)
Breakers can be operated in pulse width modulation (PWM) mode, also referred to as
dimming, to control the brightness of incandescent or LED lighting. The breaker may be
configured with a duty cycle of 5% to 100% with a resolution of 1%.
WARNING
•
The breaker being used as a dimming module will provide an active high
output at full battery voltage to the LED control module. Verify that the
LED control module can accept this type of input prior to use. When a
breaker is configured to provide a PWM output (dimming), the PWM
frequency is 200Hz, and the output current of the breaker is limited to
3.0A. Use of a breaker in a PWM mode (duty cycle less than 100%) for
control of motors or other inductive loads is prohibited.
