Single Output Switching Mode Power Supply (0-30V/0-3A)
Description
Single output switching mode power supply (0-30V/0-3A) is an electronic device used to supply constant voltage or constant current to an electrical load. Like other power supplies, SMPS transfers power from a source to a load such as a personal computer. Single output means there is one set of voltage output.
Features
30V/3A single output switching mode power supply is characteristic of overall output protection, high stability, full scale long time operation, continuously adjustable voltage and current, slim and light as well as CC/CV mode auto switching.
Advantages
1. 30V/3A single output switching mode power supply is characteristic of low consumption, high efficiency, small volume, light weight and wide voltage stabilizing range.
2. It has high filtering efficiency thus the capacity and volume of filter capacitor are greatly reduced. Therefore, it ensures high reliability of switching mode power supply.
3. This instrument has wide voltage stabilization range. When there is a big voltage change in frequency grid, adjustable power supply is able to ensure stable output voltage.

Notes
1. Single output switching mode power supply should adopt suitable line voltage.
2. The grounding conductor of power cord should be connected to ground in case of electrical shock.
Maintenance
1. The most important things are dust prevention and heat dissipation. Besides, do not operation the machine in overload condition.
2. Keep away from gas, steam, chemical deposition, dust, greasy dirt and other explosive or corrosive medium when you install DC stabilized power supply. Then the insulating property of the machine will be well-protected. Try to avoid the action of vibration or turbulence.
3. The machine should always be in a vertical state without suffering any wind, snow, ice or hail.
