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.
