Electric Sign Controller, Remote Maintenance Module – UL879
Nanov Display received the official UL48 and UL879 Compliant certification––indoor/outdoor use––for their Outdoor LCD signs and LCD controller respectively, through Underwriters Laboratories. The UL48 evaluation involves a rigorous waterproof test (4-Hour – Water Shower), a construction test (for resilience against corrosion, mechanical electrical disconnections, and damage to sealant), an electrical test (checking the circuit breaker, grounding, terminal block, Class 2 circuit, and wiring), among other testing. UL is a global safety consulting and certification company, renowned for product-testing and safety-analysis of new technology. The LCD sign controller is a critical component of Outdoor LCD Signs, and the UL required to certify UL879 component compliance guarantees its quality and ensures long term durability. Additionally Nanov has also recently completed UL879 testing of both the main board and power board.
