Product Overview HBL1025: LED Shunt For complete documentation, see the data sheet Product Description The HBL1015/25 Series are electronic shunts which provide a current bypass in the case of LEDs going into open circuit. LEDs are by nature quite fragile when subjected to transients and surge conditions. There are also many cases where high reliability of the LED lighting must be maintained such as in headlights, lighthouses, bridges, aircraft, runways and so forth. In these cases the low cost addition of the HBL device will provide full assurance that an entire string of LEDs will not extinguish should one LED fail open. The HBL device is also applicable to other loads where circuit continuity is required. The devices can be used with currents from 140 to 500 mA.
