The product of the pulse duration and pulse frequency of a pulse carrier, equal to the time per second that pulse power is applied. Also known as duty factor.

See <<duty ratio>>

1. The time intervals devoted to starting, running, stopping, and idling when a device is used for intermittent duty.

2. The ratio of working time to total time for an intermittently operating device, usually expressed as a percent. Also known as duty factor.

The percentage of time that current flows in equipment over a specific period during electric resistance welding.

The fraction of time during which a pulsed accelerator beam is on target, usually expressed as a percent. Also known as duty factor.
