WebA voltage regulator is a system designed to automatically maintain a constant voltage. Most HVDC links use voltages between 100 kV and 800 kV. Exclusively designed from the ground up by electricians for electricians. The resulting DC voltage is then switched on and off at a high frequency by electronic switching circuitry, thus producing an AC current that will pass through a high-frequency transformer or inductor. If the +5 volts is not "perfect", the game will not run at all, or will have random resets and lockups. It will work fine during an over voltage situation. Protection circuits, like reverse polarity protection, short-circuit protection and over/under voltage protection, are used to protect any electronic appliance or circuit from any sudden mis-happening. 2.
