This transformer may not be suitable for applications requiring high-power output beyond its 100VA rating or for environments where a high degree of ingress protection is required, as this unit features an IP00 rating and must be housed within a protective enclosure.
Key specifications
Rated power: 100VA
Short-time rating: 0.16kVA
Input voltage: 400V (+/- 5%)
Output voltage: 24V
Degree of protection: IP00
Dimensions: 85mm x 75mm x 91mm
Standards: IEC/EN 61558-2-2, VDE 0570, UL 506
Installation should be performed by qualified personnel in accordance with local electrical regulations. The transformer must be mounted within a suitable protective enclosure to prevent accidental contact with live parts, as the unit is rated IP00. Ensure that the input and output wiring are correctly sized for the current load and that all connections are tightened securely to prevent overheating.
What to consider before purchase
Verify that the 100VA power rating is sufficient for your specific load requirements.
Ensure the installation environment provides adequate ventilation to manage heat dissipation.
Confirm that the unit will be installed inside a protective cabinet to comply with safety standards.
Check that your supply voltage remains within the specified 400V +/- 5% range.
For optimal performance and longevity, ensure the transformer is not operated continuously above its rated power capacity and that it is installed in a clean, dry environment free from excessive dust or moisture.
