Precision voltage regulator can be divided into AC and DC voltage regulator. DC is divided into linear and non-linear voltage regulated power supply two categories. Linear power in a stable manner by points, regulator parameters and feedback adjustment regulator. Parameter regulator circuit is simple, mainly using nonlinear components to achieve regulation. For example, a resistor and a Zener diode voltage regulator constitutes parameters. Feedback adjustment regulator having a negative feedback loop, closed loop automatic adjustment system, it has the advantage of mature technology, excellent performance, stability, design and manufacturing simple.
Eight high-precision regulator maintenance tips:
First, do not overload running, try to stagger the peak load use;
Second, clean up the dust, first disconnect the power supply when maintenance to ensure safety;
Third, the installed model where the environment meets the requirements, please do not meet the improvement;
Fourth, careful cleaning of the components, especially carbon brushes, touch the bare portion of the coil, removing dirt;
Five high-accuracy voltage regulator installation environment, to ensure that the ventilation, the ambient temperature and the body temperature to normal;
Sixth, to do the conversion before the season transformers, high-precision regulator thorough maintenance, to remove safety hazards;
Seven, timely replacement of worn or damaged brush, found faulty or damaged components promptly repair or replacement;
Eight, check the precision regulator internal components and thrum whether there is loosening, for a loose connection or bad, and should be promptly treated.
