5V 10A 50W DC SMPS - High-Current Industrial Metal Case Power Supply

Product Description The 5V 10A SMPS Power Supply is a high-efficiency industrial-grade power converter designed to provide a stable 5V DC output from a standard AC mains input. Housed in a rugged, ventilated aluminum casing, this switch-mode power supply (SMPS) is engineered for long-term reliability in demanding environments. It features an adjustable output trimmer to fine-tune the voltage and built-in safety mechanisms against short circuits, overloads, and over-voltage. This unit is the primary choice for powering large LED matrix displays (like WS2812B strips), high-torque servo motors, Raspberry Pi clusters, and industrial automation sensors that require a high-current, low-voltage source.

Key Features

• High Current Output: Delivers up to 10 Amperes of continuous current, capable of powering over 150-200 WS2812B LEDs at full brightness.

• Dual Input Voltage: Features a manual toggle switch to work with both 110V and 220V AC mains worldwide.

• Precision Voltage Tuning: Includes an on-board potentiometer (V+ ADJ) to calibrate the output voltage between 4.5V and 5.5V for cable drop compensation.

• Rugged Metal Housing: The perforated aluminum case provides excellent electromagnetic interference (EMI) shielding and passive heat dissipation.

• Advanced Safety Suite: Automatic recovery from short-circuit and overload conditions ensures the connected electronics remain protected.

Technical Details

• Switching Topology: High-frequency PWM-based switching ensures high power density and minimal energy loss as heat.

• Output Stability: Maintained within +/- 1% load regulation, providing a consistent 5V even under heavy fluctuating loads.

• Terminal Block Design: Features heavy-duty screw terminals for secure connections: L (Live), N (Neutral), FG (Frame Ground), -V (Ground), and +V (Positive).

• Isolation Voltage: Input to output isolation rated at 1.5KV AC, ensuring user safety from high-voltage AC side.

• Electrolytic Capacitors: Equipped with high-temperature (105°C) rated capacitors for extended operational lifespan and low ESR.

• Ripple & Noise: Low ripple output (<100mV) prevents flickering in LED applications and logic errors in microcontrollers.

• Startup Delay: Features a "soft-start" circuit to minimize in-rush current spikes when the unit is first powered on.

• Leakage Current: Safety-optimized design with leakage current maintained below 0.5mA at 240V AC.

• Natural Convection Cooling: Perforated shell allows for airflow without the noise of a mechanical fan, ideal for quiet environments.

• Duty Cycle: Rated for 100% full load continuous operation at 25°C ambient temperature.

• Mounting Options: Standard M3 screw holes on the base and sides for secure mounting in control panels or project boxes.

• EMI Filter: Integrated EMI filter suppresses radio frequency interference (RFI) for sensitive wireless communication projects.

• Voltage Overtuning Protection: Internal Zener diode protection prevents the output from exceeding safe levels if the adjustment pot fails.

• Vibration Resistance: Components are securely bonded to the PCB to withstand vibrations in industrial or mobile machinery.

• LED Status Indicator: Green LED light provides instant visual confirmation that the DC output is active and stable.
