DC24V 75W Power Supply Unit
- Ultra-Thin Dimensions: The low 30mm height profile allows integrators to shrink the overall size of their end products, greatly enhancing industrial design flexibility.
- Maintains a reliable 24V supply with a strictly controlled ripple and noise limit of 240mVp-p, ensuring smooth operation for sensitive logic boards.
- Backed by rigorous QA and QC systems and utilizing high-quality CAPXON brand capacitors, the defect and repair rate is compressed below 0.1%~0.2%.
- Verified in an independent electromagnetic compatibility laboratory, guaranteeing the unit passes strict EMC standards to avoid signal interference with other internal electronics.
- Includes fundamental safety mechanisms such as overload, over-voltage, and short-circuit protections to safeguard downstream hardware from electrical anomalies.
- Engineered for fanless, 100% silent operation due to its efficient heat dissipation through the enclosed aluminum chassis, ideal for noise-sensitive environments.
- Powering internal control boards, coin validators, and low-power motors within confined cabinet spaces.
- Acting as a discreet power driver for indoor LED light boxes, display panels, and retail channel letters.
- Supplying steady voltage to access control panels, intercom systems, and lightweight surveillance hubs.
After-Sales Service
- A standard two-year warranty covers the units, ensuring peace of mind during the initial operational lifecycle.
- Comprehensive assistance with vessel booking, customs declarations, and obtaining designated product test reports or factory audit certifications.
- A dedicated engineering team ensures any quality feedback or integration issues are addressed swiftly to achieve complete customer satisfaction.
