Unveiling the 500W Boost Constant Current Module
Let's dive into this marvel of technology: a non-isolated boost module, otherwise known as a 500W boost constant current module, and its key attributes:
Feeding the Beast:
Our module devours direct current in the range of 8.5V-48V. The maximum input current it can swallow is 15A. Be advised, if you're pushing more than 8A, enhance the cooling system to avoid any damage. When the module is quietly at work (with 12V increasing to 20V), the idle current stands at around 10mA. However, the higher the output voltage, the more the idle current escalates.
Fine-tuning the Output:
The module flexes a 10-50V adjustable output voltage. Maximum output current is 10A, although it is inversely related to the input-output voltage difference. The larger the voltage difference, the smaller the output current. If the output current crosses the 5A threshold, don't forget to install a heat sink or fan to dissipate the heat. The constant current limit ranges from 0.2A to 10A.
Crunching the Numbers:
The output power equation is simple: input voltage multiplied by 10A. For instance, if the input is 12V at 15A, you get 180W. Need more power? You can pair two modules in parallel. So, for a 10A output, adjust each module's current to 5A.
Our module can withstand temperatures from -40 to +85 degrees Celsius. If the ambient temperature is soaring, enhance the cooling measures.
Under the Hood:
The module operates at a frequency of 150KHz, achieving an impressive conversion efficiency of up to 96%. This efficiency, however, is tied to input and output voltage, current, and pressure difference. Safety features include overcurrent protection (output over 10A) and input reverse connection protection (less than 5A).
The module, with dimensions of 70mm x 36mm x 17mm, weighs a mere 50 grams (The listed weight of .2kg is due the weight when unit is packed for transit).
Where Can You Use It?
The module is versatile. It can be used to:
- DIY a regulated power supply with an input of 12V, and an adjustable output of 12-50V.
- Power your electronics. You can set the output according to your system voltage.
- Be your car's power supply, energizing your laptop, PDA, or various digital products.
- DIY a high-powered mobile power supply for your laptop, paired with a 12V lithium battery pack.
- Stabilize solar panels.
- Charge storage batteries, lithium batteries, and the like.
A Word of Caution:
Do not attempt to adjust the current via short-circuiting – the boost module's circuit structure is not designed for this. Ensure that the output voltage is higher than the input voltage. Also, remember to connect the module to the input voltage before connecting the load when dealing with a large load.
