The Amperite Model DFW wig-wag flasher is a combination solid state/electromechanical device that is designed to alternately flash a pair of lamps on police, ambulance, school buses, EMS, and other emergency vehicles. Its flash rate of approximately 110 times per minute provides maximum warning effectiveness to both traffic and pedestrians.
The DFW flasher unit employs a pair of heavy duty automotive relays, each of which are driven by a silicon transistor connected in a switching configuration. The oscillator circuit provides proven solid state reliability while the relays allow control of heavy load currents without the need for a heat sink.
The units are small and compact, allowing easy installation in the engine compartment of any vehicle. It is epoxy encapsulated to provide maximum protection against vehicle and engine vibration. Two versions are available for installation, using quick-connect terminals or hard wiring to the vehicle harness.
On/off recycling flasher with alternating outputs. Flash rate is fixed at 110 FPM with a 50% duty cycle. Custom flash rates and duty cycles are available.
