Product Description
10kVA 480V to 240V Single Phase Dry Type Step Down Isolation Transformer
Designed for CNC machines and industrial equipment requiring 480V to 240V conversion with electrical isolation.
Product Overview
This 10kVA Single Phase Dry Type Step Down Isolation Transformer is engineered to convert 480V input to 240V output for CNC machines, automation equipment, and other sensitive industrial loads. Designed for 50/60Hz operation and IEC 61558 compliance, it provides electrical isolation between the supply and load circuits while delivering stable power. The dry-type, oil-free construction makes it suitable for indoor industrial installations where safety, reliability, and low maintenance are important.

Production Process
Frequently Asked Questions
Why is an isolation transformer recommended for CNC machines?
An isolation transformer can electrically separate the CNC equipment from the incoming power supply, helping reduce the impact of certain electrical disturbances and providing an independently configured voltage supply.
Can this transformer be used with other industrial equipment?
Yes. In addition to CNC machines, it can be designed for automation equipment, control systems, machine tools, and other loads requiring 480V to 240V conversion.
Does 50/60Hz mean one transformer can automatically operate at both frequencies?
The transformer can be designed for 50Hz, 60Hz, or dual-frequency operation. The required input frequency and voltage should be confirmed before production.
Can the transformer be customized for my machine?
Yes. We can customize the voltage ratio, capacity, frequency, terminals, enclosure, protection level, and other specifications based on your equipment and installation requirements.
