PF1224-10 ELECTRONIC POWER FLASHER This Unit was designed to flash Headlights on Police Cars and Emergency Vehicles. It has many other uses but should not be used to drive Relays etc.
530 - SS ELECTRONIC FLASHER This Unit was designed to operate 3 X 24V 21W Bulbs and a maximum of 6 in Hazard Mode. The Lamp overload feature reduces the flat-rate to 1 operation every 4 seconds if the total load exceeds 6.5 bulbs. The flat-rate increases in frequency if only 1 X 21W bulb is connected and the ‘S’ Terminal is unconnected. If 3 Lamps are connected and the ‘S’ Terminal is connected to zero volts (- 0V) the flat-rate will increase when only 2 bulbs remain connected. With the ‘S’ terminal unconnected, the ‘P’ Terminal will operate when 2 bulbs are connected. When the ‘S’ Terminal is connected to zero volts (- 0V), the ‘P’ Terminal operates when 3 lamps are connected.
