Channel Letter Transformers

Channel Letter Transformers are engineered to deliver reliable, high-performance power for illuminating channel letter signage in commercial and retail environments. Designed to provide consistent voltage and stable output, these transformers ensure uniform brightness across single or multi-letter installations—helping signage remain visible, professional, and impactful both day and night.

Built for durability and efficiency, channel letter transformers are available in indoor and outdoor-rated configurations to suit a wide range of installation conditions. Weather-resistant housings and IP-rated options protect internal components from moisture, dust, and environmental exposure, making them suitable for long-term exterior use. Advanced electrical design helps reduce power consumption without sacrificing light output, supporting energy-efficient signage systems.

Safety and compliance are key considerations in channel letter installations. These transformers are equipped with essential protections such as ground fault protection (GFP) and open circuit protection, helping safeguard installers, signage, and electrical systems while supporting compliance with industry standards. Compatible with a variety of signage types and layouts, they are trusted by sign shops and installers working with leading manufacturers like Allanson and France for dependable performance and long service life.
