Circuitron - Basic Flasher -- Adjustable Rate, LED or Lamp - HO

The CIRCUITRON BF-3 is similar to the BF-2 and may be used for the same applications, but adds the flexibility of adjustable rate and duty cycle (the time on versus time off). Two tiny trimmer controls on the circuit board allow you to set the rate from one flash every 10 seconds up to dozens of flashes per second (note that the lamp will appear steady ‘on’ rather than flashing at high rates). The duty cycle is adjustable from 5% (a very short flash) up to 95%. Input voltage of 12-18V AC/DC. All other specifications are the same as the BF-2.
