Product introduction
Our Reliable 220V Control Transformer with a New Silicon Steel Core offers a robust capacity of 50,000VA and below, perfectly engineered for input voltages of 1000V and below within AC 50-60Hz circuits. This powerhouse is designed for long-term, continuous operation at its rated capacity, making it an indispensable solution for machine tools and mechanical equipment. It serves as an essential control power supply for various general electrical appliances, local lighting, and signaling power supply needs.
· Operational capability at altitudes not exceeding 2000 meters;
· Designed to function seamlessly in ambient air temperatures ranging from -25ºC to +40ºC, with an average not surpassing +35ºC over any 24-hour period.
· Maintains optimal performance with relative humidity levels not exceeding 90% at +25°C, and staying below 50% at +40°C.
· Ideally suited for environments free from violent vibration and shock, and where protection from rain or snow is not required.
· Designed for safe operation in non-explosive atmospheres, where there is an absence of metal-corroding gases and conductive dust that can compromise insulation integrity.
With transformers tailored to differing capacities, voltages, and application needs, their structure varies, typically categorized into those with enclosures and those without.
Our transformer coils can be configured with double-winding or multi-winding options, allowing for secondary voltage and capacity customization through multiple taps or windings to meet distribution requirements.
For double winding transformer coils, the primary current is defined as 11=Pe/1, while the secondary current is 12=Pe/U2, ensuring efficient power distribution.
