The Wolf ATEX Transformers are CE marked to the 94/9/EC ATEX Equipment Directive for safe use in Zone 1 potentially explosive gas and dust atmospheres, where the T class and ambient temperatures permit.

Operating from 230V or 110V to 24V and 230V to 110V, the 400VA Ex transformers are intended for use with the Wolf range of temporary ambient and task LED and Fluorescent lights and with ancillary equipment for maintenance tasks.

As standard, Transformers are supplied with a 15 metre input cable fitted with an ATX plug and with four ATX output sockets fitted to the enclosure.

The Transformers are available with a stainless steel or GRP enclosure, sealed to IP66, enabling use in wet and dusty conditions. In addition, a stainless steel outer protective skid makes the unit stronger and easier to handle for temporary installations ensuring that it can withstand the harshest of environments.

Wolf also offers bespoke high power single and three phase ATEX transformers, which can be fitted with RCDs and MCBs plus mains distribution units, splitter boxes, extension leads and cable reels.

All Wolf’s ATEX power distribution systems are robust and durable in their construction, compact and portable for easy handling and fully flexible to enable different configurations to be built to your specific hazardous area requirement.
