Product introduction

Immerse yourself in the exceptional performance and adaptability of our High-Performance 100VA Transformer. Tailored to address the stringent requirements of contemporary machine tools and mechanical systems, this transformer is your go-to solution for circuits with input voltages up to 1000V, operating seamlessly at AC frequencies of 50-60Hz. Designed for continuous operation at its designated capacity, it effortlessly energizes general electric appliances, local lighting, and provides steadfast indicating power, boasting an incredible capacity reaching up to 50000VA.
· Expertly designed to deliver optimal performance at altitudes of 2000 meters or less;
· Consistently reliable within a broad ambient temperature spectrum from -25ºC to +40ºC, maintaining a 24-hour average temperature not exceeding +35ºC to guarantee smooth and stable operations.
· Sustains operational efficiency with relative air humidity levels not exceeding 90% at +25 °C, and staying below 50% at +40 °C, ensuring dependable performance across diverse environmental conditions.
· Designed for environments devoid of intense vibration and shocks, fortified against rain and snow infiltration, promising reliable, continual operation.
Engineered for media lacking explosion hazards, our transformers are crafted to function without the presence of corrosive gases or conductive dust, which could undermine metal strength and insulation, thereby ensuring extended safety and durability.
With a variety of designs accommodating different capacity, voltage, and usage needs, our transformers are available in both shell-encased and open-frame structures, each meticulously crafted for specific applications.
Our precision-engineered transformer coils, whether double-winding or multi-winding, enable the secondary side to harness multiple taps or windings, achieving the exact voltage and capacity distribution required for your operations.
The double winding transformer coil functions with remarkable efficiency, where the primary current is represented as I1=Pe/U1, and the secondary current as I2=Pe/U2, ensuring optimal energy conversion and distribution.
