All power supplies offer overload protection to protect both the power supply and the load tracking and wiring from overheating. This may come in a number of different guises or characteristics.

In low power products a trip and restart or “hiccup” mode is common as this helps to keep costs down by utilizing primary control schemes. Trip & restart overload schemes are generally unsuitable for loads involving high start up currents such as electromechanical equipment, lighting equipment or applications which have a high capacitive element, as start up may be unreliable and variable even from unit to unit. This overload characteristic is also unsuitable for direct battery charging applications. With these types of load a constant current overload characteristic is desirable.
