SMPS Over-Temperature Protection – Stay Cool with Made in India Parts
🔥 The Problem :
Switch Mode Power Supplies (SMPS) are known for their efficiency, but they can overheat during continuous operation, especially in compact enclosures or high-load conditions. Without proper over-temperature protection, this heat can degrade components, trip circuits, or even cause permanent damage.
✅ The Solution :
The best fix is integrating a temperature sensor (like an NTC thermistor or thermal shutdown IC) with the SMPS controller. If the temperature crosses a set threshold (say, 100°C), the circuit either throttles output or shuts down entirely, preventing damage.
🧪 Practical Example :
Let’s say you’re powering a 3D printer with an enclosed 24V SMPS. On hot days or during long prints, internal temperatures rise. Installing a thermal sensor to shut down the power if temps exceed 90°C helps avoid meltdowns or fire risks.
📐 Sample Calculation :
Using an NTC thermistor with a beta value of 3950 and resistance of 10kΩ at 25°C, you can monitor the temperature by measuring the voltage drop across a divider circuit and setting a microcontroller to trigger cooling or shutdown at around 90°C.
🛒 Product Recommendation :
