Survival Laser Adjustable Current Driver

MADE IN USA. The SL-SD-3 is an adjustable "buck" type diode driver. The SD-3 driver is sold in three output current ranges (approximately 400mA to 1.1A, 1.1A to 1.8A, and 1.7 to 3.0A at a maximum output voltage of 6 volts), and the current can be continuously adjusted by the user within these ranges. Lead wires are 1-5/8" long 26 AWG silicone insulated for flexibility and durability. Each assembly is tested before shipment. This driver is 16.8mm in diameter, fits the SL-PBR and SL-DPBR1 pill and brass ring and is designed to be powered by one (for diodes requiring less than 3.5V) or two 3.7 volt rechargeable RCR123A or 18650 batteries. Packaged in an anti-static bag.
