WebDuty cycle, sometimes called "duty factor," is expressed as a percentage of ON time. A 60% duty cycle is a signal that is ON 60% of the time and OFF the other 40%. Many loads are rapidly cycled on and off by a fast-acting electronic switch which accurately controls the output power of the load.

WebAdditionally, the ' duty cycle' is the amount of time a compressor is providing consistent pressure (PSI) and flow (CFM). So, if a compressor advertises a 100% duty cycle at 25 CFM and 125 PSI, it means that the compressor will provide 25 CFM and 125 PSI for 100% of the time with the help of a storage tank. In this example, the same compressor ... WebMar 2, 2024 · Sequence of Operation: When there is a fault, the concerned relay operates, which inturn operates the Master Trip Relay (86).
