Description
Product Overview
The 1200W DC-DC Boost Converter Module is a professional-grade, high-power step-up voltage regulator designed for the most demanding power conversion applications. This non-isolated boost converter accepts a wide DC input range of 10V to 60V and delivers an adjustable output of 12V to 90V with a maximum output current of 20A and peak power of 1200W.
What sets this module apart is its comprehensive protection system and true Constant Voltage (CV) and Constant Current (CC) control capability. Independent multi-turn potentiometers allow precise adjustment of both output voltage and current limit, making it ideal for lithium battery charging, high-power LED driving, solar system boosting, and industrial equipment power supply.
The module features dual heatsinks (large aluminum base plate and finned secondary heatsink) for excellent thermal management. An optional temperature-controlled fan can be added – it automatically activates when the module exceeds approximately 55-60°C and stops when temperatures drop, effectively reducing noise and extending fan life. The 27mm iron silicon aluminum magnetic ring inductor with multiple 1.2mm pure copper enameled wire windings ensures high efficiency and stable performance under heavy loads.
Power Rating Explanation: A 1200W rating does not mean the module can output 1200W from a 12V battery. Due to the 20A input current limit, the effective output power equals input voltage × 20A. For example, 12V input × 20A = 240W effective output; 24V input × 20A = 480W; 36V input × 20A = 720W; 48V input × 20A = 960W; 60V input × 20A = 1200W. This is not a limitation of the module but a result of the laws of physics—the input current rating determines achievable output power at lower voltages.
Key Features
-
1200W High Power Output: Delivers up to 1200W output power at 60V input. For applications requiring more than 20A, two modules can be connected in parallel (e.g., two modules at 15A each for 30A total).
-
Adjustable CV/CC Control: Independent multi-turn potentiometers allow precise setting of output voltage (12-90V) and constant current limit (0.5-20A), essential for battery charging and LED driving.
-
Wide Input/Output Range: Accepts DC input from 10V to 60V, with output adjustable from 12V to 90V. Input voltage must be lower than output voltage for boost operation.
-
High Conversion Efficiency: Achieves 92-97% efficiency (efficiency is highest when the difference between input and output voltage is small), minimizing power loss and heat generation.
-
Comprehensive Protection System:
-
Input Reverse Polarity Protection: 150A power MOS prevents damage from accidental reverse connection – can be reversed for a long time without damage
-
Overcurrent Protection: Automatically reduces output voltage when input exceeds 25-35A (model dependent)
-
Short Circuit Protection: Dual-layer protection including input 30A fuse
-
Low Battery Protection: Adjustable (8-50V) with self-recovery function – automatically shuts down when battery voltage drops too low
-
-
Temperature-Controlled Fan: Hydraulic bearing fan only activates when module temperature exceeds ~55°C and stops when cool, balancing noise and heat dissipation.
-
Dual Heatsink Design: Large aluminum base plate (5mm thick) plus finned secondary heatsink with black oxidation treatment for superior thermal conductivity.
-
High-Quality Components: Insulation board made of high-quality alumina (10× better thermal conductivity than ordinary pads), oversized ferrosilicon aluminum magnetic ring inductor with 1.2mm pure copper dual-wire windings.
-
Wide Operating Temperature: Rated for -40°C to +85°C, suitable for demanding industrial environments.
