Electronic ballast(for high pressure sodium lamp) is environmental and energy saving. It can reduce the cost, and provide stable Electronic ballast(for high pressure sodium lamp) is environmental and energy saving. It can reduce the cost, and provide stable illumination and protections. Safety and reliable. Electronic ballasts are high-tech products which is both environment friendly and significant in energy saving. It greatly reduces the cost in power supply circuit, stabilizes the lighting, and is for general power supply; while with its multi-protecting function, and high safety , it greatly prolongs the lifespan of tubes or bulks. Obviously, this product greatly improves the quality of illumination, and reduces the operation coast. As an economic and applicable ballasts, it is the ideal upgraded products to replace inductive ballasts Features: Use special HID control chip. Constant output power within the working range, temperature compensation, dual-frequency work mode against stroboflash, no DC or bias current on the lamp side. Protection against over current, over voltage, break, short circuit, reverse polarity.
