Encapsulated electromagnetic copper/iron ballasts for use with an external semi-parallel ignitor for CDM, CDO, MH, HPI (Plus) and SON lamps
Benefits
Excellent resistance to chemical impact, humid conditions and environmental stress crack
Long-lasting reliable solution – outstanding product lifetime of 15 years average
Minimal watt losses thanks to orthocyclic winding process
Control gear can be installed remotely
Features
Encapsulated with thermoplastic polyester resin, reinforced with glass fiber
Equipped with screw terminal blocks as standard; insert contacts available upon request
Ballasts for alternative mains voltages/frequencies available upon request
Separate earth terminal (HID ‘Heavy Duty’)
System
Electromagnetic system requires ballast, ignitor and capacitor
Semi-parallel circuit: if ballasts with “L” in their description (e.g. BSN 100 L307…) are used, SN(D)… ignitors are required; if ballasts with “K” in their description (e.g. BSN 100 K307…) are used, SK(D)… ignitors are required. Capacitor value to match system power can be found on lamp/ballast combination sheet
Series circuit: all ballasts are designed to work with series ignitors
No ignitor needed for SON-I lamps
Applications
Outdoor lighting (most popular application: road and tunnel lighting)
