DC POWER SUPPLY

1. This power supply is widely used in fields such as broadcasting and television transmission, communication, power electronics, scientific research, electroplating, water treatment, and aging of battery charging products.

2. Adopting a switch mode power supply circuit with low ripple design, the ripple is close to that of a linear power supply, and the efficiency is much higher than that of a linear power supply. It is small in size and lightweight. Multiple protections for overvoltage, overheating, and overload.

3. Important components are imported with original packaging, and the circuit design is optimized and reasonable. The production process is strict and complete, ensuring the reliability and stability of the machine.

4. Wide input voltage range.

5. The output voltage regulation and current regulation values can be continuously adjusted from 0V to the rated value.

6. Allow the input voltage to decrease accordingly when the output voltage decreases.

7. Both output stabilization and current stabilization are sampled from the output, thus achieving high stability and reliability.

8. If the output current needs to be increased, multiple units can be directly connected in parallel without the need for current sharing processing.

9. Input overcurrent, overvoltage, and undervoltage protection; Output short-circuit, overcurrent, overvoltage protection; Overheat protection for the entire machine.

9. Intelligent temperature controlled fan for heat dissipation.

10. Built in EMI filter.
