描述： Ultrasave’s broad line of electronic ballasts for T5 linear fluorescent lamps utilizes programmed start technology which prolongs lamp life in frequent on-off applications. These ballasts can operate 1 or 2 T5 lamps on multiple input voltages from 120 to 277 volts or 277 to 347 volts at 50/60 Hz. This reduces SKU requirements and inventory carrying costs, ?resulting in significant cost savings. A 90°C case temperature rating makes these ballasts ideal for high ambient temperature environments. All of the ballasts are also designed with a lamp end-of-life protection circuit, a safety feature that automatically shuts off power as the lamp approaches its EOL, thereby preventing overheating and protecting the ballast.?The 4-lamp 35 watt ballasts with wire leads are the latest additions to the popular line of T5 ballasts and are available in multiple input voltages from 120 to 277 volts and dedicated 347V at 50/60 Hz. These ballasts are designed to operate 3 or 4 T5 lamps reliably at a high ambient temperature of 90°C.Programmed start lamp ignition?
