Its compact and durable build allows for seamless integration into existing electrical panels, while the high-quality materials used in its construction guarantee a long service life even under continuous operation.

Suitable for

Industrial control panels and automation systems
Voltage regulation for control circuits
Powering auxiliary equipment in machinery
Electrical distribution systems requiring 230V output from 400V sources

When it may not be suitable

This transformer is not intended for outdoor use or environments where it may be exposed to moisture, dust, or corrosive elements, as it features an IP00 protection rating. It is also not suitable for applications requiring power levels exceeding its 100VA continuous rating or 0.16kVA short-time rating.

Key specifications

Rated power: 0.1 kVA (100VA)
Short-time rating: 0.16 kVA
Rated input voltage: 400V (± 5%)
Rated output voltage: 230V
Degree of protection: IP00
Standards: IEC/EN 61558-2-2, VDE 0570 Part 2-2

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes and the provided technical documentation. The transformer must be mounted within a protective enclosure to compensate for its IP00 rating. Ensure that the input terminals are connected to the 400V supply and the output terminals are correctly wired to the control circuit load. Proper ventilation must be maintained around the unit to prevent overheating during operation.

What to consider before purchase

Verify that the 100VA power rating is sufficient for your specific load requirements.
Ensure the installation environment is dry and protected, as the unit is IP00 rated.
Confirm that the input voltage matches your supply network within the specified 5% tolerance.
Check available space in your control cabinet for mounting.

Usage recommendations

Always ensure the transformer is properly grounded and that all connections are tightened to prevent electrical arcing. Regularly inspect the unit for signs of dust accumulation or thermal stress to maintain optimal performance and safety.
