Power inverters can have several types of certifications, some of the most important of which are a Network Equipment-Building System (NEBS) certifications, which Bell Labs initiated in the 1970s. There are three levels of NEBS certification, with the third level being the most comprehensive in terms of a device’s performance under adverse conditions. If any of the conditions below are present in the area where a power inverter is placed, it should have a level 3 NEBS certification.

Heavy Vibration

Standard inverters have parts that can malfunction when they are consistently exposed to heavy vibration. If you need to place an inverter in an area that consistently produces vibration, such as an assembly line, be sure to invest in a device that has a level 3 NEBS certification.

Airborne Contaminants

Airborne contaminants such as Volatile Organic Compounds (VOCs) and chemicals from solvents can harm more than workers. They can also cause inverter components to corrode. If an inverter will be exposed to airborne contaminants, it should have a level 3 NEBS certification.

Fluctuating Temperatures

Fluctuating temperatures can damage mechanical parts and part housings by causing them to rapidly expand and contract. Over time, the repetitive expansion and contraction can lead to warping. Inverters in area that has fluctuating temperatures need a level 3 NEBS certification.

High Moisture

Equipment that is consistently exposed to moisture can start to oxidize from the inside out, with rust damaging electrical connections, nuts and bolts, and anything else that is not stainless. This is why inverters should have a level 3 NEBS certification if they are exposed to high moisture.
