A 12V 20A Metal Chassis SMPS is a high-power, industrial-grade power supply unit engineered to convert standard AC household mains into a highly stable 12V DC output. Capable of delivering a massive continuous current of up to 20 Amperes (240 Watts total power), this unit features a heavy-duty perforated aluminum enclosure with an exposed terminal strip. It is widely used across India to run large LED digital signage boards, heavy-duty 3D printers with high-temp heated beds, 16-to-32 channel centralized CCTV camera networks, thermoelectric Peltier cooling matrices, and high-torque CNC stepper motor driver rails.
✨ Key Features
- Heavy-Duty Screw Terminal Block: Built with an open terminal strip featuring robust protective barriers, allowing you to secure thick-gauge wire lugs or fork terminals safely.
- Smart Active Cooling Fan: Equipped with an internal cooling fan that automatically triggers based on temperature thresholds or current loads to keep components operating efficiently.
- Dual Input AC Selector Switch: Features a manual sliding switch (110V / 220V toggle) on the internal circuit board to let you manually adjust input parameters before deployment.
- Manually Tunable +V ADJ Potentiometer: Outfitted with a precision variable adjustment screw to tune the output range between roughly 10.5V and 13.5V DC to compensate for wire voltage drop over long distances.
