Introducing the ST111/ST151/ST171 series of fluorescent tube lamps starters from OSRAM. These high-quality devices have been designed to ignite every time, reliably and quickly. Each starter is a subject to strict manufacturing and quality control tests. Thanks to using the excellent quality components, these starters ensure long-life operation of up to 4 years and extend the lamp life by 20%. The case is made of Makrolon (self-extinguishing plastic) and meet the conditions laid down for protection class II.
• DEOS? ST 171 SAFETY, DEOS? ST 172 SAFETY and DEOS? ST 173 SAFETY are safety starters
• DEOS? ST 172 SAFETY is a safety starter for series circuits (tandem circuits)
• DEOS? ST 171 SAFETY, DEOS? ST 172 SAFETY and DEOS? ST 173 SAFETY are designed to operate with conventional control gear (CCG) and low-loss gear (LLG)
• They reliably disconnect burnt-out or faulty lamps under inductive or capacitive operating conditions
• They are instantly ready for operation when the red button is pressed in (there must be an audible click)
• The automatic cutout circuit protects the choke and the starter itself
• Four times the life of conventional starters
• To ensure reliable ignition and operation the DEOS? ST should be replaced after every four lamp replacements.
• Temperature range for reliable cutout: -20°C…+80°C
• Extends the lamp life by 20%
• Self-extinguishing plastic casing made of Makrolon. Class V2
• Equipped with special radio-interference suppression capacitor (foil winding capacitor)
• Suitable for 220V-240V AC operation. 50/60 Hz, series circuit and single circuit 4W ...22W at 110V/127V

NOTE: To ensure reliable ignition we recommend that you also replace the starter when you replace the lamp. Starters cannot be used for OSRAM DULUX S/E, D/E, T/E or T/E IN lamps.
