The Wolf ATEX 250VA Transformers are for use in high ambient temperature hazardous areas and CE marked to the ATEX Directive and IECEx Certified for safe use in Zones 1 potentially explosive gas and 21 dust atmospheres, where the T4 temperature class permits with an upper ambient temperature of +55°C.

Operating from 230V or 110V to 24V and 230V to 110V, the transformers are intended for use with the Wolf range of temporary ambient and task 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 have a 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.

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.
