Very basic power supply circuit boards may consist of a transformer, four diodes or a block rectifier, and one or more capacitors for filtering. The board will have a connection for the input voltage and a switch to turn the supply on or off. A fuse should be incorporated in the circuit. Some electronic components can become hot while operating, and these may be attached to heat sinks to prevent overheating.
uninterruptible power supply (UPS):is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails. ups pcb is a core part of the system. Wonderfulpcb is professional electronic ups control pcb boards OEM in china.
