Product Overview
The Wolf ATEX Transformers are designed for safe use in potentially explosive environments, specifically Zones 1 for gas and 21 for dust atmospheres. They are CE marked and certified under both ATEX and IECEx standards. These transformers are available in models that convert 230V or 110V to 24V and 230V to 110V, suitable for powering Wolf's temporary lighting and maintenance equipment. They offer dual power ratings of 400VA and 320VA, allowing for use in various ambient temperatures.

Design and Features
The transformers come with a 15-meter input cable and four ATX output sockets. They are housed in either a stainless steel or GRP enclosure, both sealed to IP66 for protection against wet and dusty conditions. A stainless steel protective skid enhances durability and portability, making them ideal for temporary installations in harsh environments.

Features & Benefits
  • ATEX and IECEx certified for explosive gas and dust atmospheres.
  • Robust, durable, and portable design.
  • Available in multiple voltage configurations: 230V or 110V to 24V and 230V to 110V.
  • Power ratings of 400VA and 320VA.
  • Equipped with 4 ATX socket outlets and a 15m SY cable with ATX plug.
  • Optional CEAG, STAHL, and Marechal plugs.
