LM317T Voltage Regulator with Pass Transistor

Krauler Voltage Stabilizers of VR-SD SeriesDo you remember those olden days when TV sets were large and black-and-white? At that time many homes had small black boxes next to their TV sets. TV sets were connected to them, and they, in turn, were connected to the mains. These boxes were called voltage stabilizers, and they served to protect TV sets and other electronic appliances from power surges in the network. Since then much time has passed, technologies have made a big step forward, and the quality of power supply has improved. Nevertheless, power surges that can damage electronics, even though they are quite rare, still may occur even in modern power supply networks. Besides, anyone may face the problem of a storm or a short-circuit.The device we're going to consider (Krauler's VR-SD) is an automatic voltage stabilizer and it is basically a descendent of those black boxes which once protected TV sets of our grandmothers and grandfathers against power supply instability. Being designed using modern technologies, Krauler VR-SD is able not only to level off power drops, but can also perform other functions to ensure quality power supply for the devices connected to it. This became possible due to the most reliable stabilization circuit - a circuit that uses a servomotor, which provides an ideally smooth voltage regulation, and supports devices with high starting currents, such as refrigerators, washing machines or electric drills.The stabilizer connects the load to the ...
