DC power supplies provide consistent DC power to machinery and equipment in areas where AC power is not available or accessible. DIN-mount DC power supplies with overload protection are typically used for starting high in-rush loads. Linear power supplies are commonly used for providing low-noise, reliable DC power for control and processing applications. AC-to-DC converters with overload protection are suitable for powering heavy-duty equipment. A switching DC power supply provides a range of power ratings, output voltages, and styles for applications with changing power demands.
