DC-DC Isolated Power Supply Module, 10V-24V to +/- 12V-18V Dual Output, 1A Audio Pre-Amp Converter Board for Car Audio Workbench & DIY Op-Amp

When engineering custom audio equipment or sensitive sensor arrays, ground loop noise and voltage mismatches are common hurdles. This DC-DC isolated power supply PCBA is designed to address these challenges with objective precision. It converts a standard single DC input into a symmetrical, adjustable dual voltage output (±12V to ±18V), which is critical for driving operational amplifiers and audio pre-stages. Unlike enclosed consumer adapters, this bare board is intended for direct integration into complex systems such as audio testing workbenches, DIY instrumentation setups, and microcomputer hubs. It requires foundational electrical engineering knowledge for safe operation, particularly in managing the REM activation terminal and dual-rail grounding. Users must accurately calculate their specific loads to ensure the output current remains within the 1A operational threshold, preventing overload and ensuring long-term system stability.Compliance & Testing: Component-level PCBA for hardware integration; intended for operation strictly within Extra Low Voltage (ELV) parameters.CPSC eFiling Integration: Harmonized Tariff Schedule (HTS) categorization applicable for unhoused industrial DC power regulators.Input Voltage: DC 10V - 24V (Single Supply)Output Voltage: DC ±12V - ±18V (Dual Positive and Negative Output, Continuously Adjustable)Max Output Current: 1AProtection Mechanisms: Overload, Over-temperature, Short-circuit protectionControl Terminal: REM (High-level active; connect to IN+ to enable)Dimensions: 58mm x 61mmPackage Includes: 1 x DC-DC Isolated Power Supply Module

• SINGLE TO DUAL OUTPUT ISOLATION: Engineered for precision audio and instrumentation projects, this DC-DC converter PCBA transforms a single DC 10V-24V input into a highly stable, adjustable dual positive and negative DC ±12V to ±18V output.
• 1A CURRENT FOR AUDIO PRE-AMPS: Designed specifically for low-power, high-fidelity applications. It delivers a maximum output current of 1A, providing a clean and isolated power source essential for audio pre-amplifiers, operational amplifier (op-amp) circuits, and sensitive signal processing.
• REMOTE CONTROL ACTIVATION (REM): Features a dedicated REM terminal for flexible power management. The module requires a high-level signal (connecting to the input positive terminal or a standard switch logic) to activate, ensuring power is only drawn when your connected system is operational.
• PRO-LEVEL WIRING STRICTLY REQUIRED: Designed exclusively for experienced electrical engineers. This is an isolated dual-voltage supply; mixing positive (+), negative (-), and ground (GND) lines will result in immediate catastrophic failure. Integrated overload, over-temperature, and short-circuit protections mitigate basic faults, but proper circuit design is mandatory.
• VERSATILE DIY INTEGRATION: An essential component for advanced workbench environments. It provides reliable isolated voltage regulation for RV dashboard audio stabilization, custom audio workbenches, ham radio testing setups, and specialized CCTV or IoT hub sensor arrays.
