220V to 105V 3 Phase Isolation Transformers

Why Equipment Cannot Connect Directly to the South American Grid

If the heating and mixing furnace adapted to 105V is directly connected to the 220V power grid in South America, it will cause a series of chain problems.：

• The output power of the heating tube is insufficient, the furnace body cannot reach the standard constant temperature, and the temperature control interval continues to be low.；
• The operating speed of the mixing motor is unstable, resulting in uneven mixing of materials and poor production consistency.；
• After abnormal working conditions continue to accumulate, it can easily cause the line to overload and burn down, and the furnace temperature control is completely out of control, which directly leads to production failures and safety hazards.
• The heating mixing furnace runs at high temperature and high current. If there is no electrical isolation, the clutter of the power grid will interfere with the temperature control accuracy, causing equipment false positives and downtime, and increasing production risks.

How the Transformer Works

The transformer works based on the principle of electromagnetic induction: the primary winding is connected to the South American 220V three-phase power grid, and the secondary winding outputs a 105V three-phase voltage to complete the voltage level conversion.；

Electrical isolation is achieved through insulation between the primary and secondary windings, so that the furnace body side circuit and the power grid side circuit are electrically independent of each other, and the power grid clutter and grounding interference cannot be transmitted to the equipment, and the temperature control and sensing system are protected from the source.

Typical Applications

• Chemical raw material mixing furnace: high requirements for temperature control accuracy, relying on electrical isolation to protect the temperature control system, reduce false alarms and downtime failures.
• Food processing heating furnace: the voltage is accurately matched to ensure uniform and stable heating, and it is suitable for continuous production.
• Metal smelting and mixing equipment: voltage conversion and electrical isolation can be stably completed under high current conditions.
• Other heating and stirring equipment exported to South America with a rated three-phase voltage of 105V.
