Control transformers are essential components in industrial automation and electrical systems, designed to provide stable and isolated voltage for control circuits. They step down higher primary voltages (e.g., 480V or 240V) to standardized lower voltages (typically 120V or 24V) to power relays, solenoids, PLCs, and other control devices safely. Key features include high efficiency, compact design, and robust insulation to withstand harsh environments. Common products in this category include single-phase and three-phase control transformers, encapsulated models for moisture resistance, and multi-tap transformers for flexible voltage adjustments. These transformers ensure reliable operation of automation equipment while protecting sensitive control components from voltage fluctuations.
