What this product does and why you need it 40W adjustable boost DC power module that converts 6–36V input to an adjustable 0.5–36V output. It delivers 0–4.5A output current within the 40W power limit, giving a compact, accurate supply for bench testing, prototyping, and field debugging. Modular design: the power board and the display/control unit can be used together or independently, so you can integrate the board into projects or use the display as a standalone controller. Key benefits Precise, adjustable power: wide input/output range and a fineadjustable regulator let you test circuits and devices across common voltages without swapping supplies. Faster repeat setups: 11 memory presets and silicone pushbuttons provide onetouch recall for common voltage and current settings, speeding repetitive tests and onsite repairs. Clear, reliable readout: a 0.8inch LCD with a 36 × 29 mm viewing area shows realtime voltage, current and system parameters with wideangle visibility for easy monitoring in different working positions. Builtin safety and durability: multiple protection mechanisms (antireverse connection, overvoltage, overcurrent, overpower, undervoltage and additional overprotections) with thresholds help prevent damage from electrical faults and extend component life. Features and specifications Power rating: 40W maximum output Input voltage: 6–36V DC Output voltage: adjustable 0.5–36V DC Output current: 0–4.5A (subject to 40W maximum) Display: 0.8inch LCD, viewing area 36 × 29 mm Controls: silicone buttons, 11 memory presets Design: modular — power board and display unit usable independently Protections: antireverse connection, overvoltage, overcurrent, overpower, undervoltage, plus additional overprotections with useradjustable thresholds Practical applications (examples) Electronics bench testing: power small boards, sensors, or controllers while monitoring voltage and current during functional checks and troubleshooting. CNC and motor controller debugging: supply and tune drivers or control electronics when developing or repairing CNC controllers and similar equipment. Field service and DIY projects: portable, adjustable power for field repairs, hobby projects, and onsite diagnostics where quick preset recall and builtin protections are valuable. Compatibility, size and performance notes Compatible with a wide range of 6–36V supplies and devices that accept 0.5–36V inputs. Observe the 40W maximum to avoid exceeding power capability. Compact modular format allows easy integration into custom enclosures or temporary bench setups; use the display for convenient control and monitoring or mount the power board directly in equipment. Why this module stands out Combines a wide input/output range, memory presets, a clear wideangle display and comprehensive protections in a modular package, making it a practical, safe and flexible choice for lab work, device debugging and DIY electronics.
