    Product Details

    This charger is a high-efficiency, wall-mount AC/DC switching power adapter designed to deliver a regulated 24V 3.75A (90W) DC output. It uses a universal 100–240VAC, 50/60Hz input stage, allowing deployment in most regions that use standard AC mains (with suitable plug compatibility and approvals).

    The adapter is housed in a compact black enclosure with a UL 2-pin AC plug and an integrated DC output cable of approximately 1.2m. Internal design includes high-frequency switching, EMI filtering, and multiple protection circuits to ensure stable, low-ripple output for sensitive loads.

    With efficiency level VI, low standby power, and compliance to ETL 62368-1 and FCC Part 15B, this adapter is suitable for 24V powered equipment that requires consistent performance, electrical safety, and adherence to modern energy-efficiency standards.


    Usage Notes & Safety Instructions

    General Use

    • Use only on AC mains within 90–264VAC, 50/60Hz.

    • Ensure the connected device is rated for 24V DC and does not exceed 3.75A / 90W.

    • Plug the adapter firmly into a properly grounded, standard AC outlet.

    Environment

    • Operate the adapter within 0–40°C ambient temperature and 5–90% RH, non-condensing.

    • Avoid placing it near heat sources, in direct sunlight, or in very humid or dusty environments.

    • For storage, keep within –20 to +65°C and away from corrosive or conductive contaminants.

    Connection & Handling

    • Do not pull the adapter by the DC cable; hold the housing when unplugging from the wall.

    • Avoid bending or sharply twisting the DC cord; repeated mechanical stress may damage the cable.

    • Ensure good ventilation around the adapter; do not cover it with cloth or place it in confined, unventilated spaces.

    Safety & Protection

    • If the adapter shuts down due to over-current, short-circuit, or over-voltage, remove the load and unplug from AC. After the fault is corrected, reconnect; the unit is designed for auto-recovery.

    • Do not attempt to open, modify, or repair the adapter—this can defeat safety isolation and void compliance.

    • Do not use the adapter if the housing is cracked, the cable is damaged, or you notice unusual smell, noise, or excessive heat.

    Intended Use

    • Designed for equipment requiring 24V DC supply up to 90W, such as certain industrial devices, consumer electronics, and LED or control systems that match the rating.

    • Indoor use is strongly recommended; if used near moisture, ensure it is protected from water spray and condensation.
