This transformer may not be suitable for high-voltage applications exceeding its rated insulation levels or for environments with extreme electromagnetic interference that could compromise measurement accuracy. It is also not intended for use in circuits where the primary current consistently exceeds the specified transformation ratio.
Key specifications
Transformation ratio: 300/5A
Accuracy class: 0.5
Power rating: 2.5VA
Maximum cable diameter: 30mm
Busbar compatibility: 40x10mm, 20x30mm, 25x25mm
To use the LOVATO Electric DM3T0300, ensure the primary conductor passes through the center of the transformer aperture. Secure the device firmly using the provided mounting accessories to prevent vibration or movement. Connect the secondary terminals to your measuring device or relay using appropriately sized wiring, ensuring that the polarity is correctly observed to maintain measurement accuracy. Always verify that the secondary circuit is never left open while the primary circuit is energized.
What to consider before purchase
Verify the primary current of your system matches the 300A rating
Check the physical dimensions of your cables or busbars against the aperture size
Ensure the secondary load does not exceed the 2.5VA power rating
Confirm the required accuracy class for your specific application
For optimal performance, ensure that all electrical connections are tightened to the manufacturer's specifications and that the transformer is installed in a location free from excessive heat or moisture. Regular inspection of the secondary wiring is recommended to ensure system integrity.
