Product information

Description

The Legrand 042857 safety transformer is a professional-grade electrical component engineered for precise voltage conversion in demanding environments. With a power rating of 100VA, this unit is designed to step down primary voltages of 230V or 400V to a stable 24V output, ensuring reliable operation for low-voltage control systems and industrial equipment.

Advantages

This transformer offers exceptional reliability and safety for electrical installations. Its robust construction ensures consistent performance under continuous load, minimizing the risk of overheating or electrical failure. By providing galvanic isolation between the primary and secondary circuits, it enhances the safety of connected equipment and personnel, making it an ideal choice for complex control panels and automation systems where stability is paramount.

Suitable for

Industrial control circuits
Low-voltage lighting systems
Automation and signaling equipment
Professional electrical distribution panels

When it may not be suitable

This transformer is not intended for high-power applications exceeding its 100VA rating. It is also not suitable for outdoor environments unless housed within an appropriate IP-rated protective enclosure to prevent moisture and dust ingress.

Key specifications

Power rating: 100VA
Primary voltage: 230V or 400V
Secondary voltage: 24V
Design: Safety transformer

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. The transformer is typically mounted on a DIN rail or a flat surface within a control cabinet. Ensure that the primary input wires are connected to the correct terminals corresponding to either the 230V or 400V supply. The secondary 24V output should be wired to the control devices, ensuring that the total load does not exceed the 100VA capacity of the unit.

What to consider before purchase

Verify that the 100VA power capacity is sufficient for your specific load requirements.
Ensure the input voltage of your supply matches either 230V or 400V.
Check the available space in your control cabinet for proper ventilation.

Usage recommendations

Always verify the input voltage before energizing the transformer to prevent damage. Ensure that the secondary circuit is protected by an appropriately rated fuse or circuit breaker to prevent overcurrent conditions.
