LVD 200w Induction Electronic Ballast Power Supply Ballast Only Design: LVDs new ballast design has a tailoring baseboard complication, which is convenient for ballast heat dissipation LVDs electronic ballast features THD of less than 10%, constant output wattage, and fail-safe protection. Multi-Voltage: Can be used in various voltage specifications such as AC 220V/347V, 110-277V, etc Switching: The overlong switch stability can make it work well in occasions of frequent turning on and off the switches. Convenient for making the ballast voltage signal smooth and stable in order to achieve a stable overall property of the ballast
