Machine tool control circuits
When it may not be suitable
This transformer is not intended for use in high-power applications exceeding its 250VA rating. It is also not suitable for outdoor environments unless housed in a protective enclosure that meets the required IP rating for the specific installation site.
Key specifications
Power rating: 250VA
Input voltage: 400V or 230V AC
Output voltage: 24V AC
Phase: Single-phase
Design: Safety transformer
How to use
Installation should be performed by a qualified electrician in accordance with local electrical codes. The transformer should be mounted securely in a well-ventilated area to ensure proper heat dissipation. Connect the primary side to the appropriate 400V or 230V power source and the secondary side to the 24V load. Ensure that all connections are tightened properly and that the system is grounded according to the manufacturer's guidelines.
What to consider before purchase
Verify that the 250VA power rating is sufficient for your total load requirements.
Ensure the input voltage matches your available power supply (400V or 230V).
Check the physical dimensions to ensure the unit fits within your intended enclosure.
Confirm that the environment is dry and free from excessive dust or corrosive elements.
Usage recommendations
Always install a suitable fuse or circuit breaker on both the primary and secondary sides to protect the transformer and the connected equipment from potential overcurrent or short-circuit conditions.
