Electronic fluorescent lamp ballast BLP 59-S

The BLP 59-S is a full electronic, controllable AC power supply for ssr uv-lamps from about 3000 to 6000 watts nominal power and designed for industrial purposes. It is tuned especially to operate with mercury discharge uv-lamps. The lamps are driven with square-wave current, through this the obscuring period during the zero-axis crossing of current, occurring at sinus-shaped supply (standard power supply), is dropped.
