Federal Signal's Pulsator® 551 Plus features a state-of-the-art power supply for
improved light output and warning effectiveness. This high-profile strobe combines
advanced dome optics with a high-performance power supply to produce a brilliant
Flash that meets SAE Class 2 requirements.
Pulsator 551 Plus strobes are exceptionally durable. The power supply is moisture
and vibration resistant and protected against reverse polarity, voltage spikes and
RFI. The patented base design and O-ring gasket combine to seal out moisture and
contaminants. All models feature modular construction that provides quick access to
internal components. The impact-resistant, polycarbonate, dome and base provide
added durability in heavy-duty applications.
Heavy Duty models feature a gel-filled base that completely encases the power
supply for extra protection against vibration and moisture. The encased power
supply allows superior performance in extreme high-vibration environments.
Pulsator 551 Plus models are available in 10-joule (Double & Quad-Flash) and 8-joule
(Double-Flash), 12-48 VDC versions and 115 Volt (5-joule/single & Double-Flash) AC
versions. All models use a helical strobe tube that is easily replaceable. All models
include the necessary mounting hardware.
