1800W 40A DC to DC Adjustable Constant Voltage and Current Power Supply Boost converter Module

Presenting the 1800W 40A DC to DC Adjustable Constant Voltage and Current Power Supply Boost Converter Module. This module serves as a non-isolated DC power converter, providing a high-power and stable output by converting 10-60V DC to 12-97V DC. Its use of high-quality components ensures remarkable conversion efficiency, reaching up to 97%.

Equipped with intelligent features, the module includes a temperature control fan that operates automatically when the temperature hits approximately 60℃. It ceases operation when the temperature drops below 60℃, contributing to efficient temperature management.

This versatile module finds applications in driving high-power solar street lamps, powering various LED lighting systems with constant voltage (CV), supplying power to vehicle-mounted and mobile devices, creating do-it-yourself adjustable constant voltage and constant current (CV CC) power supplies, solar power charging, and various battery charging scenarios. Its adaptability and robust performance make it an ideal choice for a range of power supply needs.

1. Boost Converter Module:
– The module operates as a boost converter.

2. MLCC Ceramic Capacitor:
– MLCC ceramic capacitors are added to both input and output, reducing output ripple to about 100mV at 48V to 72V 4A.

3. Airfoil-Type Heat Dissipation:
– Utilizes airfoil-type heat dissipation for excellent heat dissipation, allowing for even greater output power (up to around 1800W with a 48V input and fan).

4.Large Power Tube:
– Features a 100V 210A TO-247 large package power tube, providing a substantial power margin and good dynamic response.

5. Temperature-Controlled Fans:
– Equipped with temperature-controlled fans using hydraulic bearing technology, striking a balance between noise and heat dissipation. The fan operates automatically when the load temperature reaches around 60 degrees, reducing noise and extending the fan’s life.

6. Adjustable Undervoltage Protection:
– The undervoltage protection is adjustable, effectively safeguarding various batteries and can be used for solar cells.

7. Output Current:
– Maximum output current is 35A. For loads exceeding 15A, replace the existing heatsink with a larger one and a fan to enhance heat dissipation.

8. Constant Range:
– The potentiometer allows adjustment within the constant range of 0.8-28A (+/-0.3A).

9. Output Power:
– Output power is calculated as Input voltage * load current (less 5% loss due to efficiency).

10. Working Temperature:
– Operating temperature range is -40 to +85 degrees. For high ambient temperatures, enhanced heat dissipation is recommended.

11. Operating Frequency:
– Operates at a frequency of 150KHz.

12. Conversion Efficiency:
– Achieves a high conversion efficiency, up to 93 to 97%.

13. Overcurrent Protection:
– Yes, with adjustable output current limit. When the current exceeds the limit, it automatically reduces the output current to a minimum of 5A, varying according to the load current nature.

14. Short Circuit Protection:
– Yes, 3 20A fuses connected in parallel protect against accidental short circuits.

15. Input Reverse Polarity Protection:
– Yes, features 150A power MOS reverse protection.

16. Input Low Voltage Protection:
– Yes, adjustable from 10V to 50V, with self-recovery.

17. Input Over Current Protection:
– Yes, automatically protects when input exceeds 40A, preventing an increase in power supply voltage.

18. Output Counter Filling:
– Yes, for charging without requiring a blocking diode.

19. Installation Hole:
– Four 3mm screws for installation.

20. Connection Type:
– Solderless terminals for output.

21. Module Dimensions (L x W x H):
– 130x52x80.

22. Weight:
– 419g.
