Regulator Accessories --circuit board

The utility model has a voltage regulator and the public of a time delay function of voltage regulator circuit board, including a group of upward circuit and a group of down circuit, described by the two-signal comparison circuit increases circuit, delay circuit and the lock circuit Among them, a group of comparison circuit connection signal delay circuit.The delay circuit is connected to the lock circuit, and the lock circuit also connects to another set of signal comparison circuit; described the reduction in the signal circuit is also compared by two circuits, delay circuit and lock circuit, in which a group of comparison circuit connection signal delay circuit, the delay circuit connected to the lock circuit. The lock circuit also connects to another set of signal comparison circuit.The above-mentioned delay circuit is set to achieve adapted for large load of frequent intermittent power supply system operating efficiency; the lock through the above circuit can realize the function adjustable voltage and reduce voltage drift so that the number of actuator movements, thus contributing to long-term stable operation.
