HID ignitors for MK4 semi-parallel systems
Compact ignitors for flexible luminaire design
HID ignitors for semi-parallel systems
Product Benefits
•Wide range of lamps covered by one ignitor
35-600 W
•Digital versions ensure longer lifetime than
series ignitors, and silent operation
•Smaller dimensions than predecessors mean
it fits more easily into compact luminaires
Product Features
•Designed to ensure maximum performance
with new MK4 ballasts
•Semi-parallel ignitor will only work in
semi-parallel circuits and must be matched
with the relevant ballast
•Ignitors equipped with screw terminal blocks
as standard
•Lightweight and compact products
•Current flows through ignitor only at lamp
start-up
Application
•Outdoor lighting
System
•Electromagnetic system requires ballast,
ignitor and capacitor
•Designed to work only in semi-parallel cir-
cuits: 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
•No ignitor needed for SON-I lamps
