Luma-Fuse™ is a high quality fault indicating fuse
incorporating a built in bi-directional LED chip. Failed
circuits are easily detected at a glance as the LED will
light when the fuse blows regardless of current direction.
The innovative design of Luma-Fuse™ began from the ground
up, and is not simply a modified fuse with an indicator
added later as with earlier incandescent or "glued on" LED
light styles. The superior sensitivity of the Luma-Fuse™ LED
chip even detects low currents such as found in memory keep
alive circuits. The low current consumption, typically 2 mA
on a 12 volt circuit, keeps drain on battery powered systems
at a minimum, while allowing safe operation of the
Luma-Fuse™ on circuits up to 32 volts.
