A power supply Singapore provides electricity-to-electricity loads in devices. They convert one form of electricity to another. Some control the output voltage to a steady level or a compatible value and are called regulated power supplies. They control the current and stabilise it, avoiding sudden fluctuations and power surges. Power supplies that convert AC current to DC current are common and widely used.
