Duty cycle

The time between activation and deactivation of the solenoid system excitation current is referred as the duty cycle.

The sum of duty cycle and idle interval is the cycle period.

The term "relative duty" (%) means the percentage ratio of duty cycle to cycle period:

relative duty = (duty cycle/cycle period) x 100 [%].

The term "continuous duty" means the duty mode in which the duty cycle lasts until the steady-state temperature is reached in practical terms (100 % duty) as the result of heating of the solenoid.
