Specifications:
Input voltage: AC200-240V
Output: Dual voltage ± 50V/6A; Independent 19V/0.5A (unstable, decreasing with the main voltage, used in situations with low requirements, such as supplying power to fans. Different main voltages have different independent voltages, and the purchase title indicates it)
Special reminder: As the switching power supply only stabilizes the main voltage, the independent and auxiliary output current must be less than the current output by the main voltage; For example, the current of the main voltage at that time is 10mA, and auxiliary and independent devices cannot carry loads above 10MA;
Voltage stabilization accuracy: main no-load ± 3%, on-load ± 3%; (When AC220V input)
Rated continuous power: 300W (with an ambient temperature of 25 ℃ and a fan)
Instantaneous power: 600W (can work for 30 seconds with an ambient temperature of 25 ℃ and a fan)
Conversion efficiency: Max 98%
External dimensions: length, width, height=116 * 67 * 40mm
Weight: 265g
Packing List:
1* Switching Power Supply
NOTE:
1. This product is a bare board with high voltage circuit hazards and must be purchased by someone who can use it. Our store will not bear any consequences caused by use!
2. For commercial purposes, some circuits and components are polished and encrypted, and schematic diagrams, PCBs, and technical support are not provided
3. For long-term high-power use, please add a fan for air cooling. The power supply is equipped with overheating, overcurrent, and short circuit protection. The overcurrent and short circuit protection is locked protection, and the main filter capacitor voltage must be disconnected from the AC power supply and reduced to 0V before starting again. This power supply is a true LLC power supply, with a high-frequency sine wave resonant circuit. It is not an ordinary square wave switching power supply, and is very suitable for use in power amplifiers with good results
4. Each power supply is tested before shipment, and our store is not responsible for any burnt transformers, pipes, or ICs. If maintenance is required, we will bear all costs ourselves! The board is constantly upgraded and revised, and the component circuit may be modified.
