Przetwornica napięcia 1200W 20A DC Step-Up podwyższająca 8-60V na 12-83V

DC-DC Step-Up Converter 1200W 20A

A high-performance step-up voltage (Step-Up) module with maximum output power of 1200W. The converter lets you power circuits at a higher voltage than the available supply. The module operates from an input voltage of 8V - 60V DC and allows smooth adjustment of the output voltage from 12V to 83V DC. The design offers high efficiency up to 95% and stable switching operation.

The module is versatile and well suited to advanced electronic projects. It can successfully be used to power microcontroller-based systems, including Arduino, ESP8266, ESP32, and Raspberry Pi.

Key technical specifications

• Input voltage: 8V - 60V DC

• Maximum input current: 20A (active cooling recommended above 10A)
• Maximum output current: 20A
• Maximum output power: 1200W
• Converter efficiency: up to 95%
• Switching frequency: 150kHz
• Short-circuit protection: input fuse
• Operating temperature: from -40°C to +85°C
• Module dimensions: 133 mm x 52 mm x 43 mm

Advanced features and adjustment

The converter includes three multiturn potentiometers for precise tuning. The CV potentiometer sets the output voltage, while CC limits the maximum output current. The module also has minimum input voltage adjustment (RV1), which protects against over-discharge of the supply-a critical feature when powering from Li-Ion or Li-Po batteries.

The PCB has a large aluminum heatsink for heat dissipation. When operating above 10A, the module provides a dedicated 12VFAN connector for a cooling fan. Voltage appears on this output automatically when the board temperature rises.

Example applications

• Powering lighting systems based on high-power LEDs
• Charging batteries with a higher nominal voltage from lower-voltage sources
• Powering audio amplifiers that need higher voltage in 12V automotive installs
• Powering laptops and portable IT gear from car batteries
• Building high-output bench and lab power supplies
• Powering drives in e-bikes and electric vehicles

Benefits

• High current capability for very demanding loads
• Stable parameters-set output voltage does not drift with input voltage variations
• Built-in protection against short circuits and excessive discharge of the supply battery
• Safe charging-the circuit allows battery charging without an extra protection diode on the output
• Automatic cooling control via a dedicated 12V fan connector

Important safety information

The module has no reverse-polarity protection on the supply input. Incorrect wiring of the input leads will permanently damage the converter. Always measure and set the output voltage before connecting the load. The device is intended for integration into larger systems and requires basic electronics knowledge.
