DC power supplies are electronic devices that provide a stable and continuous flow of electrical current with a fixed polarity and voltage level. Unlike Alternating Current (AC), which periodically reverses direction, DC current flows steadily in one direction. [pdf]
Direct current (DC) electricity is what solar panels produce and what batteries hold in storage while alternating current (AC) electricity is the type used on the grid and in most household devices. [pdf]

Yes, an outdoor power supply is essentially a type of power battery. It typically includes a built-in lithium-ion battery that allows it to store electric energy, functioning as a portable energy storage solution2. This makes it similar to a battery, as it can provide power for various devices when needed3. [pdf]

The current relevant standard for power supplies is EN61204-3: 2000. This covers the EMC requirements for power supply units with DC output (s) of up to 200V, at power levels up to 30kW, and operating from AC or DC source voltages of up to 600V. The "EN" refers to Euro Norm or European standard. [pdf]
