Power Supply Housing for 3dPrinter Enclosure

This is a custom power supply and enclosure control unit designed specifically for 3D printer enclosures, perfect for maintaining stable ambient temperatures during ABS printing (~50°C).

Features & Hardware Specifications:

• 12V DC Output via XT60 Connector: Supplies stable 12V power for external accessories.

• 5V Power via Dual USB Ports: Powers enclosure LED strip lights, camera modules, or auxiliary 5V devices.

• Integrated Solid State Relay (SSR): Features a CoG ZGT-25 DA (25A, 3-32V DC control)

• SSR to safely trigger and switch AC load heating elements or 1500w space heaters.

• Temperature & Heater Control: Designed to interface with an [STC-1000][4] (or similar) digital temperature controller to automatically turn a space heater on and off, keeping internal enclosure temperatures consistently around 50°C to prevent warping during ABS prints.

• Digital Voltmeter & Battery Level Display: Real-time visual monitoring of DC bus voltage (e.g., 12.2V).

• Built-in AC Panel Outlet: Front-panel US AC outlet for plugging in external AC devices directly.

• Active Cooling System: Equipped with an LED-lit cooling fan, protective grill,

• A speed control potentiometer to regulate the 120mm exhaust fan, efficiently venting ABS fumes out of the enclosure.

• Main AC Power Entry: Standard IEC C14 inlet with an integrated master rocker switch.
