When it may not be suitable

This transformer is not intended for high-power applications exceeding its 250VA rating. It is also not suitable for outdoor environments unless it is housed within a protective, weather-resistant enclosure.

Key specifications

• Power rating: 250VA
• Input voltage: 400V
• Output voltage: 24V
• Phase: Single-phase
• Application: Safety and isolation

How to use

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The transformer must be mounted in a well-ventilated area to ensure proper heat dissipation. Connect the 400V supply to the primary terminals and the 24V load to the secondary terminals, ensuring that all connections are tightened securely. Always verify that the input and output voltages match the requirements of your specific equipment before energizing the system.

What to consider before purchase

• Verify that the 250VA power rating is sufficient for your connected load.
• Ensure the input voltage of 400V matches your power supply network.
• Check the available space in your electrical cabinet for mounting.
• Confirm that the required output voltage is 24V.

Usage recommendations

Ensure that the transformer is protected by appropriate circuit breakers or fuses on both the primary and secondary sides to prevent damage from overloads or short circuits.
