The Pulsator® 551 Plus has been updated for improved performance. The Pulsator 551 Plus features a new state-of-the-art, 10-joule, 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), 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.
