This driver is a "buck" type switching power supply fixed current regulated diode driver circuit, delivering 1.25A +/- 50mA of regulated current at a recommended input voltage of 4.2 to 8.4 volts. It is suitable for use with 445nm blue as well as the new 635nm 500mW red Mitsubishi diodes. When used with a 445nm diode the optical output will be approximately 1-1.3W. The switching regulator IC chip has an efficiency as high as 91%, which means that no driver heat sinking is required. Driver circuit board is 16.8mm in diameter and fits P/N SL-PBR1 Pill & Brass Ring, which in turn fits the C6, Survival Laser S4 and Survival Laser stainless steel host assemblies. Lead wires are approximately 1" long. Note:
These drivers are 100% tested and have a layer of silicone adhesive applied to a critical area to prevent shorting against the brass ring typically used during installation in the driver pill. CAUTION:
We strongly recommend that you test any driver assembly with a "dummy load" to verify proper current output before attaching to a diode. Click here
