This Ultrasave ED20-1MMH E-HID MH PCS 20W Multi-Volt 120-277V THERM P is an HID Ballast.
Ultrasave's low wattage electronic ballasts for metal halide and high pressure sodium lamps are the ultimate choice for your HID needs. These high quality ballasts utilize programmed cold start technology for 20 to 150 watt lamp types, and are offered in multiple or dedicated input voltages of 120, 120 to 277 and 347 volts at 50/60 Hz. Our HID ballasts are designed with superior lamp wattage regulation, optimizing lamp colour stability and reducing lamp-to-lamp colour variations. In addition, these ballasts offer significant energy savings and cost reductions over incandescent and magnetic HID alternatives. All of the ballasts have a 90°C case temperature rating to promote long life in high temperature applications and several enhanced protective features including thermal and programmed electronic protections. These protections prevent overheating issues by shutting down the system should the lamp fail to ignite or cycle on and off at end of life.
The latest additions of 70, 100 and 150 watt models incorporate a dedicated 120VDC output designed for use with self heating thermal protectors. This product enhancement offers fixture manufacturers the necessary power source for connecting to a thermal protector and protection against fixture overheating."
