Step-Down Transformer | Reliable Power Transfer | Compact Design
The 21:4 Transformer is a step-down transformer designed to convert input voltage at a 21:1 primary-to-secondary winding ratio, effectively reducing voltage while maintaining stable power flow. It is ideal for use in welding machine control circuits, power supply units, and industrial electronics where controlled voltage regulation is critical.
