3 Bulletin Product Overview Selecting a Control Circuit Transformer For proper transformer selection, three characteristics of the load circuit must be determined in addition to the minimum voltage required to operate the circuit. These are total steady-state (sealed) VA, total inrush VA, and inrush load power factor. Total steady-state (sealed) VA is the volt-amperes that the transformer must deliver to the load circuit for an extended period of time the amount of current required to hold the contact in the circuit. Total inrush VA is the volt amperes that the transformer must deliver upon initial energization of the control circuit. Energization of electromagnetic devices takes milliseconds. During this inrush period, the electromagnetic control devices draw many times normal current times normal is typical. Inrush load power factor is difficult to determine without detailed vector analysis of all the load components. Such an analysis is generally not feasible. Therefore, a safe assumption is % power factor. Selection Process. Determine the total inrush VA of the control circuits from the table below. Do not neglect the current requirements of indicating lights and other devices that do not have an inrush VA but are reenergized at the same time as the other components in the circuit. Their total VA should be added to the total inrush VA.. Refer to the table below, Regulation Data Inrush VA. If the supply circuit voltage (Step ) is reasonably stable and fluctuates not more than ± %, refer to the % secondary voltage column. If it fluctuates as much as ± %, refer to the % secondary voltage column. Go down the column selected until at the inrush VA closest to, but not less than, the inrush VA of the control circuit.. Read to the far left side of the chart. The transformer s continuous nominal VA rating is now selected. The secondary voltage that will be delivered under inrush conditions will be either %, %, or % of the rated secondary voltage, depending on the column selected from the table below, Regulation Data Inrush VA. The total sealed VA of the control circuit must not exceed the nominal VA rating of the transformer selected from the table below, Typical Magnetic Motor Starter and Contactor Data Hz, Volt, -Pole.. Refer to the specification tables on the following pages to select a transformer according to the required continuous nominal VA, and primary and secondary voltage combinations.
