Product Specifications

Technical details and manufacturing context for Control Transformer

Definition
A control transformer is an essential component within Motor Control Centers (MCCs) that steps down the main incoming power voltage (e.g., 480V AC) to a lower, safer voltage level (typically 120V AC or 24V AC) specifically to power the control circuits, relays, contactor coils, pilot lights, and other logic devices that manage the operation of the motors.
Working Principle
It operates on the principle of electromagnetic induction. The primary winding, connected to the main power supply, creates a varying magnetic field in the transformer's core. This varying magnetic field induces a proportional voltage in the secondary winding, which is connected to the control circuit. The ratio of primary to secondary windings determines the step-down voltage ratio.
Common Materials
Electrical Steel (Silicon Steel), Copper Wire, Insulation Materials, Laminated Core
Technical Parameters
  • Rated Volt-Ampere (VA) capacity, indicating the maximum load the transformer can supply to the control circuit. (VA) Per Request
