Custom PoE Injector Powers Explosion-Proof CCTV Camera

Eaton MEDC Ltd. recently used a modified version of Contemporary Controls' Skorpion PoE Mid-Span Injector to provide a compact power source in their CCTV camera housings.

PoE applications require a 48 VDC power source, but most automation systems operate from 24 VAC/VDC power. For Eaton's application, only one Ethernet Powered Device (PD) needed power, and Contemporary Controls Skorpion PoE injector met this criteria. In addition, Eaton was looking to customize the injector for use in a CCTV camera and reached out to Contemporary Controls for original design manufacturing (ODM).

"The speed of response with which Contemporary Controls modified and then certified the product to fit our needs enabled us to secure more business with our customer," said Brian Taylor, Product Line and Support Manager CCTV Hazardous Area Communications at Eaton MEDC.

Eaton's CCTV cameras and housings are made from 316L corrosion-resistant stainless steel and are designed for use in harsh environmental conditions and hazardous areas where there is a risk of explosion due to the presence of flammable atmospheres.

Contemporary Controls' standard PoE comes in its own rugged metal enclosure; however, Eaton required the completed product to be enclosed in the explosion-proof camera housing without the Skorpion's metal enclosure.

Eaton tested the standard Skorpion PoE Injector for its operation with the CCTV camera. Next, the team at Contemporary Controls worked with Underwriter Laboratories (UL) to obtain the necessary approvals for the PoE Injector without its enclosure. This new, compact design fits easily inside the camera housing, and comes certified and application-ready.

"We design, develop and manufacture our products in-house, which gives us a huge advantage for ODM projects," said Bennet Levine, R & D Manager at Contemporary Controls. "When a customer contacts us about modifying one of our products, we have the resources on hand to deliver a solution, from design to the regulatory approval process."
