Product introduction

Introducing our high-performance Reliable 220V Control Transformer, a powerhouse in its class with an impressive capacity reaching up to 50,000VA. Specifically engineered for input voltages soaring to 1000V within AC 50-60Hz circuits, this transformer epitomizes efficiency and reliability. Built to sustain optimal performance even at full capacity, it is the perfect choice for machine tools and mechanical equipment. As a steadfast control power supply, it seamlessly supports general electrical appliances, localized lighting, and indicator power sources, making it a versatile and indispensable asset.
· Perfectly suited for settings where the altitude remains below 2000 meters;
· Skillfully designed to function within ambient air temperatures from -25ºC to +40ºC, ensuring the average temperature over a 24-hour period does not exceed +35ºC.
· Optimized for conditions where air relative humidity stays below 90% at +25°C, and does not go beyond 50% at +40°C.
· Constructed to endure environments devoid of harsh vibrations or shocks, ensuring complete protection from rain or snow exposure.
Meticulously engineered for safe environments, free from explosion hazards, with no presence of gases or conductive dust that could potentially corrode metals or impair insulation quality.
Our transformers are meticulously crafted to meet an array of capacity, voltage, and application specifications. We offer a diverse selection of structural designs, commonly categorized into encapsulated and open-shell configurations, to cater to varied demands.
The transformer coils are adeptly designed with either double or multiple windings, featuring secondary windings with multiple taps or independent coils to ensure precise voltage and capacity distribution.
For double-winding transformer coils, the equations are elegantly simple: primary current I1 equals Pe divided by U1, while secondary current I2 equals Pe divided by U2.
