Phantom Variable Watt Digital Ballast, 250W/400W, 120/240V was developed from our popular Phantom II ballast line. It retains all of the reliability and engineering superiority of the Phantom II models and adds 250W/400W switching capability as well as three-way output control, making it highly versatile. Output wattage is selected using a recessed switch on the rear panel.
Like the Phantom II ballasts, the PHB2040 is totally silent, energy efficient, reliable, and lightweight. Its industry-leading Smart Alert Technology utilizes a 32 MHz fully integrated microprocessor to keep your setup running smoothly.
The Phantom PHB2040 has built-in hot re-strike programming to protect the lamp and ballast in the event of a temporary loss of power. The ballast will not attempt to restart a hot lamp for at least 15 minutes.
