Whelen ULF44 4-Channel LED Flasher – 62 Flash Patterns, 5 Amps per Channel

The Whelen ULF44 four-channel LED flasher turns steady-burn LED and Super-LED® lightheads into a coordinated warning package. It runs alternating, simultaneous, or synchronized patterns from one compact, fully encapsulated module. Put it behind the perimeter lights, grille lights, and body-mounted LEDs on your rollback or wrecker when you want every light working together instead of blinking at random. Whelen ULF44 Specs Outputs: 4 outlets / 4 independent channels Capacity: Up to 5 amps (60 watts) per channel. Do not exceed. Flash patterns: 62 Scan-Lock™ patterns: alternating, simultaneous, and synchronized Inputs: Scan-Lock pattern select and synchronization Protection: Short-circuit and thermal protection on every channel Construction: Fully encapsulated for water and shock resistance Voltage: 12 VDC Dimensions: 1-5/8" H x 2" W x 2-3/4" L (41 x 50 x 70 mm) Why Operators Run the ULF44 Five amps per channel is a lot of headroom for LED lightheads. You can run more than one light on a channel as long as the combined draw stays under 5 amps. Scan-Lock lets you cycle through the patterns and lock in the one you want without a laptop or programming cable. The small footprint fits behind a body panel or inside a toolbox compartment where a bulkier controller won't. Fitment The ULF44 is not vehicle-specific. It is designed for LED and Super-LED® lightheads wired for steady burn. Before you install, confirm that your lightheads support steady-burn operation and add up their amp draw per channel.
