1.Product Overview

The product is made under high-frequency inverter power supply technology, also it combined with street lamp’s high pressure sodium technology. We call it the second generation broadband inverter ballast that is much better than anyone on the market currently whatever in output power, harmonic, output power stability, protective response. Moreover advanced structural design is good for lightning protection, waterproof and anti-surge. Not only energy-saving effect better than ordinary electronic ballast, but also life-span and reliability approaching traditional inductive ballast.

2.Fundamental Principles

Frequency ballast makes use of high-frequency inverter technology and high-frequency digital inverter technology in sodium lighting control in SPWM mode which can control the wick power subject to the demands of output power from *0K to **0k so as to reach a constant voltage variable power control while improving the wick ignition speed and protecting wick aging because over temperature of ignition.  The time for ignition is highly shortened to ms level and there is a constant output voltage in ignition that can avoid the surge voltage injury to wick. Moreover it can remote control to wick power. As a result of the use of wide range of inverter technology ballast can maintain over *5% output efficiency if output power from *0% to **0% or from **0 to **0 VAC.

3.Excellent Performance

In the existing market, high pressure sodium lamp electronic ballasts are made in traditional inductive and low frequency electronic model. An example of a **0w wick are as follows:
