480W Adjustable DC Switching Power Supply Switch Mode Power Supply 0.28" Display (Output 0-24V 20A)

480W Adjustable DC Switching Power Supply Switch Mode Power Supply 0.28" Display (Output 0-24V 20A)

Features:
- 0.28" Digital DC Voltmeter: Good stability and high test accuracy
- The voltage can be adjusted all the way
- Thickened aluminum alloy shell. The open-hole design makes it more thermally conductive and the power supply operates more stably
- Cooling fan (ultra-quiet) with intelligent temperature control: When the temperature reaches a certain level, the fan runs automatically. When the temperature does not require cooling, the fan automatically stops
- With a 110V/220V switch; widely used around the globe
- Premium components: Two imported power tubes, imported 494 chip, imported fast rectifier tubes, double imported electrolytic capacitors, FR-4 sheet double-sided double-layer PCB, and high-frequency low-resistance filter capacitors
- Pure Copper: Transformer, inductor, common mode, and drive

It is mainly used in various DC equipment, DC motor stepless speed regulation, LED stepless dimming, chemical electrolytic plating speed regulation, scientific research testing, student experiments, etc.

Attention:
When using inductive loads such as motors and fans, please pay attention to the motor starting current parameters. This parameter should not be higher than the current used by the power supply, otherwise the power supply may be damaged. You should choose a power supply with a larger current, or equip the motor with a soft-start protection circuit to absorb the inrush current.
