BALLAST POWER SUPPLIES FOR METAL HALIDE LAMPS
A complete range of high quality ballast power supplies specially designed to ensure correct operation and long life to metal halide lamps with power from 200 to 12000W.
They are characterized by high linearity and are made up of a reactor in series to the mains, a battery of power factor improving capacitors and a power relay for the remote ignition of the power supply (some models are equipped with a special type of L-C circuit).
Some of them are fitted with an input autotransformer to obtain the noload voltage value required by the lamps. A main circuit breaker protects the unit against short circuits or over current phenomena.
Their peculiar design guarantees a low acoustical noise, a high robustness, an easy handling and makes them particularly suitable for a wide variety of applications.
