What is DC Power Supply?

The DC power supply is a device that creates and supplies a stable Direct Current (DC) from the AC power supply of the outlet. It is used as a power source to run electronic circuits or to check electronic devices.

For example, household power outlets in Japan are provided with 100V AC, but minute voltage fluctuations actually occur due to losses during the power supply and changes in power consumption of devices connected to the same power source.

Fluctuations in the voltage supplied to home appliances with relatively simple structures, such as vacuum cleaners and fans, do not pose much of a problem. However, for precision devices such as electronic equipment, a slight change in voltage can cause malfunction.

Also, since DC power is required to run electronic devices, the supplied AC power must be converted to DC power. A DC stabilized power supply is used for this purpose.

Stabilized DC power supplies can be divided into two types depending on the output method: constant voltage power supplies and constant current power supplies. In constant-voltage power supplies, the output voltage is controlled so that it remains constant even if the power supply load changes. On the other hand, constant-current power supplies are controlled so that the output current remains constant.

DC power supply, also known as an AC to DC power supply, Regulated power supply, or Programmable DC power supply, Bench power supply, Lab power supply, variable DC power supply, is a power circuit that supplies a constant voltage or current. They are roughly classified into Linear regulator and switching regulator types according to the control method.

Zingzonetek’s DC power supplies are high-performance DC regulated power supplies (DC power supplies)/bidirectional power supplies (regenerative power supplies) that pursue “compactness,” “low noise,” and “high power.
