Duty cycle is the proportion of time during which a component, device, or system is operated. Suppose a disk drive operates for 1 second, then is shut off for 99 seconds, then is run for 1 second again, and so on. The drive runs for one out of 100 seconds, or 1/100 of the time, and its duty cycle is therefore 1/100, or 1 percent
Used when computing failure rates based on active and dormant settings The duty cycle is equal to the percentage of total time the item or system is in the active environment
The ratio of operating time versus total cycle time of a motor A motor has a continuous duty rating if it continues to operate for an indefinite amount of time and its normal operating temperature remains within the temperature limits of its insulation system A motor has an intermittent duty rating if it never reaches a steady temperature, but is allowed to cool between operations
1) The ratio of time on to time off in a recurring event 2) The operating regime of a cell or battery including factors such as charge and discharge rates, depth of discharge, cycle length a length of time in the standby mode
The ratio of average power to peak power, or ratio of pulse length to interpulse period for pulsed transmitter systems Interpulse period is equal to the reciprocal of the pulse repetition rate
The length of time the laser beam is actually cutting, drilling, welding, or heat-treating, as compared to the entire work cycle time
Proportion of "on" time to "off" time, usually stated as a percentage
In a circuit, the ratio of off time to on time
A measure of a motor's "on" time or operating time relative to "off" time or rest time Typically expressed as a percentage of "on" time to total cycle time
(noun) The fraction of time a system is actually employed in performing its function In printing systems, the percent of time that printing is carried out as opposed to the time the system is inactive
The relationship between operating time and the resting time of an electric motor Continuous Duty: The operation of loads for over one hour Intermittent Duty: The operation during alternate periods of load and rest Usually expressed as 5 minutes, 30 minutes or one hour
The ratio of the lengths of the positive to negative halves of a waveform expressed in percentages
The time duration and use frequency during which a battery is drained (i e 2 hours/day)
The relationship between the operating time and the resting time of an electric motor Motor ratings according to duty are
The operating regime of a battery including factors such as charge and discharge rates, depth of discharge, cycle duration, and length of time in the standby mode
percentage of time the motor is on
The total time to one on/off cycle Usually refers to the on/off cycle time of a temperature controller
The percentage of time during an arbitrary test period, usually 10 minutes, during which a power supply can be operated at its rated output without overloading
The percentage of a pulse cycle during which the current is turned on (on-time) relative to the total duration of the pulse cycle Same as PERCENT ON- TIME See also ARC DURA TION
The measure of output waveform uniformity This term, also referred to as symmetry, is a measurement of the time that the output waveform is in a logic high state, expressed as a percentage (%) This parameter is measured at a specified voltage threshold or at a percentage of the output waveform amplitude (Figure 1)
A percentage of the time "on" (transmitting) versus the time "off" (not transmitting)
The percentage of time during a 10 minute period that a welder is rated to run for Common Arc Welders have a 20% duty cycle, which means you can weld for two minutes out of every ten
Percentage of time a compressor unit can operate at full load over a thirty minute period (104) Comments?

Operating time at specific loads compared to total operating time plus idle time
The ratio of "on" time to "off" time for an electronic component or signal In a power system duty cycle is typically used in reference to the semiconductor switch (in PWM controlled systems) or clock signal
The percentage of time a transformer will be supplying the Full Rated Power to the load Percentage of time a unit is expected to perform at Full Rated power versus time spent in idle can significantly affect the physical size of a transformer
