The 5V 5A (25W) DC Metal Case SMPS is a high-performance industrial power converter designed for maximum durability and heat dissipation. At Electrapac, we recommend this "Cage-Style" power supply for permanent installations where reliability and high current output are non-negotiable.

Product Overview

This Switch Mode Power Supply (SMPS) converts standard AC mains electricity into a highly regulated 5V DC output. Encased in a ventilated aluminum shell, it utilizes passive air cooling to remain stable under load. Unlike plastic "wall-wart" adapters, this unit features a fine-tune adjustment screw, allowing you to calibrate the voltage precisely to compensate for voltage drops in long wire runs.

Key Features for Electrapac Customers

• Industrial Grade Build: The perforated metal housing provides excellent EMI shielding and physical protection for the internal components.

• Precision Voltage Tuning: The "ADJ" trimpot allows you to dial in exactly 5.0V (or slightly higher, 5.2V, to overcome resistance in long LED strips).

• High Efficiency: Modern switching technology ensures minimal energy loss, keeping your Electrapac projects energy-efficient and cool.

• Screw Terminal Block: Features heavy-duty barrier terminals for secure wiring, supporting thicker gauge cables that can handle the full 5A current.

• Universal AC Input: Designed to work globally with an internal 110V 220V selector switch.

Wiring & Safety Guide

To ensure a safe and professional installation, follow the labeled terminals:

1. L (Live) & N (Neutral): Connect your AC power cord here.

2. FG /  (Ground): Connect the Earth/Ground wire to the metal casing for safety.

3. -V (COM): The negative DC output (Ground).

4. +V: The positive 5V DC output.

5. ADJ: Use a small screwdriver to fine-tune the output voltage while measuring with a multimeter.

Safety Warning: Ensure the input voltage switch (110V 220V) is set to your local grid standard BEFORE applying power to avoid damaging the unit.

Primary Applications

• Digital LED Strips: Powering up to 100–150 pixels of WS2812B (Neopixels) or SK6812 RGB LEDs.

• Raspberry Pi Clusters: Providing a stable, high-current 5V rail for multiple microcomputers.

• Industrial Automation: Powering 5V logic controllers, sensors, and HMI displays.

• 3D Printers: Providing secondary power for 5V peripherals like Noctua fans or Raspberry Pi Octo Print servers.

• Arcade/Gaming DIY: Perfect for powering retro arcade cabinets and JAMMA boards.

Why Shop at Electrapac?

We source our 25W Metal SMPS units with high-quality filter capacitors to ensure low ripple and noise, preventing "flicker" in LEDs or "reboots" in microcontrollers. At www.electrapac.com, we provide the heavy-duty power foundations that keep your large-scale builds running 24/7.
