The TCP 20B50 Emergency Fluorescent Ballast is a critical component of an emergency lighting system designed for use in commercial and industrial settings. This particular ballast, model number 20B50, is specifically engineered for use with 4-lamp T12 or T8 fluorescent bulbs and comes with a 1400ms delay feature.
This emergency ballast is assembled with robust technologies that ensure reliable performance under various circumstances. The 1400ms delay function enables the ballast to stay in standby mode until normal power is lost, allowing the backup battery to supply power during an outage. This characteristic makes it an ideal solution for maintaining safety and compliance with emergency lighting codes.
Moreover, this ballast is compatible with both magnetic and electronic ballast-compatible bulbs, providing versatility for various applications. The high-quality components are complemented by UL-Listed and CE marked certifications which underscore its conformity with industry safety and performance standards.
Its compact, slender design allows for easy installation and mounting. It features convenient terminal connections, accommodating both quick-disconnect and screw terminals, ensuring a seamless installation process. Additionally, its electrical connectivity includes a Neutral (N) input for the normal electrical power source, an Auxiliary (A) input for the backup power source, and a 'TEST' switch to allow for periodic testing of the emergency backup system.
The TCP 20B50 Emergency Fluorescent Ballast incorporates advanced technology and reliability, making it an indispensable component for any emergency lighting installation seeking to meet safety codes and enhance overall system performance.
