Switching power supply (power adapter) is more efficient than traditional silicon steel transformer power supply, low cost, and now more and more widely used in various industries, the use of simple and convenient.
But now the market some products, some products, if the overload or overcurrent, will cause more serious transformer overheating, burn out the transformer insurance, now portable transformers are generally used glass insurance tube, or directly with a 100 ohm resistor for protection, although can protect the transformer, but this the protection is disposable, burn, must to solve the problem by replacing the fuse. Now if we use self recovery fuse, we use Shenzhen tage electronic (TERGY) to replace the traditional fuse or resistance, immediately solve the problem.
If the load is too large because of the switching power supply or short-circuit current, self recovery fuse (TERGY) immediately into high resistance, not by a fault current, exclusion can automatically recover, greatly facilitate the use of this application is the trend of development.
