When it may not be suitable

This transformer is not intended for high-power applications exceeding its 100VA rating, as overloading may lead to overheating or permanent damage. It is also not designed for outdoor use without a protective enclosure, nor is it suitable for applications requiring variable voltage output.

Key specifications

• Power rating: 100VA
• Primary voltage: 400V
• Secondary voltage: 230V
• Phase: Single-phase
• Type: Safety transformer

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The transformer must be mounted securely within a dry, well-ventilated enclosure to prevent overheating. Connect the primary 400V input to the designated terminals and the secondary 230V output to your load, ensuring that all connections are tightened to the specified torque. Always verify that the input voltage matches the transformer specifications before energizing the circuit.

What to consider before purchase

• Verify that the 100VA power rating is sufficient for your total load requirements.
• Ensure the installation environment is free from excessive moisture and dust.
• Check that the input and output voltage levels match your specific system needs.

Usage recommendations

For optimal longevity and safety, ensure the transformer is installed with appropriate circuit protection, such as fuses or circuit breakers, on both the primary and secondary sides to prevent damage from short circuits or overloads.
