What is transformer % Duty Cycle?

Duty cycle is a measurement of the % of the time that the transformer is conducting current during one minute. This value is used to insure that the electrical components are not operating above their thermal capability. Resistance welding transformers are rated at a 50% duty cycle. Each application may operate at different duty cycle up to and including 100% continuous.

THE FORMULA TO CALCULATE DUTY CYCLE FOR AC is:

Duty Cycle AC

THE FORMULA TO CALCULATE DUTY CYCLE FOR MFDC is:
