Solis Tek 600 Watt Digital Ballast 120/240v
600 Watt Dimmable BallastFeatures: Allows dimming from 600w, to 400w, to 360w. Includes Solis-Boost overddrive setting.Ignition ControlTM - Revolutionary safety measure.  Whether you are powering up  10 units or 100 units of Solis-Tek Ballasts, the electric current draw is controlled by our internal software. Our software will ignite lamps at different times within 5 seconds in order to protect breakers from overloading (also ignites with soft start).  This is especially important for automated systems to protect against inconsistency in lighting schedules.Connection Awareness -  Solis-Tek units will not ignite without a complete and proper connection.  The ballast conducts a 3 second test of the connection circuit.  If the circuit is incomplete ignition will be prevented in order to protect the lamp-120v/240v compatibleable in 400 watt, 600 watt, and 1000 watt outputs.-High Pressure Sodium and Metal Halide switchable-Electronic dimming functions    -1000 watt settings: Solis-Boost - 1000 watt - 600 watt - 400 watt   (4 step dimming)    - 600 watt settings:  Solis-Boost - 600 watt - 400 watt - 360 watt   (4 step dimming)    - 400 watt settings:  Solis-Boost - 100% - 75% - 50%   (4 step dimming)-2 meter power cord included-Soft start-Constant power, 99.9% efficiencyOffering protection against:-output open-short circuit-ignition failure-thermal-end of lamp life-overflow current-over/low voltage-high/low temperatures
