Electronic Ballasts and Step-Down Transformers
- Ballasts are NEMA Premium high-efficiency, except UltraStart 2TNU3, 2TNU4, 4GCG8, 5LB99, and 5LE10; UltraMax 3CB72; and ProLine 1PCV6, 4PRX2, 1PLY4, 2RTY9, 1PCV8, 1PCW5, 4XLC4, and 4XLC5. Min. starting temp.: -20 F, except 0 F for ProLine models and 50 F for 3APT8. All are RoHS compliant. UltraStart Programmed Start are for frequently switched applications where occupancy sensors are used. Soft start helps extend lamp life. Start up to 3 times faster than standard programmed-start ballasts. Provide the same energy savings as UltraMax ballasts and can improve lamp life by about 50% at 12 or more starts per day. Parallel mode operation keeps other lamps on the system working when 1 lamp fails. UltraMax Instant Start provide up to 44% more energy savings over standard electromagnetic T12 ballasts. Multivoltage control (MVC) adapts automatically to voltages from 108 to 305V, ande a thermal foldback circuit protects the ballast from overheating. Anti-striation control assures better light quality. Feature UL Type CC anti-arc rating. ProLine Instant-Start feature active power factor correction and parallel lamp operation to ensure continued operation when 1 lamp fails. High frequency, less than 10% THD. UL Listed.
