The Pulsator® 451 Plus features a state-of-the-art, 8-joule, power supply for improved light output and warning effectiveness. This low-profile strobe combines advanced dome optics with a high-performance power supply to produce a brilliant flash that meets SAE Class 2 requirements.

Pulsator 451 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.
