AC380V (323–437V) to 12VDC Charge Power Supply — ACDC Converter with DCDC Boost/Buck (500W / 400W) Key benefits Reliable 12V DC output from voltage AC sources: converts AC380V (wide input range 323–437V) to a stable 12VDC supply for charging and powering 12V systems. Two power options to match application needs: available in 500W and 400W ratings to support higherload or standard installations. Multifunction converter: combines ACDC conversion with DCDC boost and buck capability to maintain 12V output from varying input conditions, reducing downtime and simplifying power design. What this product solves Eliminates the need for multiple power stages by providing ACDC conversion plus DCDC regulation in one unit. Allows equipment that requires 12V DC to operate reliably from voltage AC sources with wide voltage fluctuations (323–437V). Provides a dedicated chargingcapable supply for 12V battery systems or to power 12V electronics directly. Key attributes Input voltage: AC 380V nominal with a supported range of 323–437V. Output voltage: 12V DC. Power ratings: 500W model and 400W model (select per application). Functionality: ACDC conversion and DCDC boost/buck regulation; intended as a charge power supply and general 12V power source. Compatibility: Designed for use wherever a stable 12V DC source is required from a voltage AC input (see use cases). Size and material: Refer to the manufacturer's model specifications for exact dimensions and enclosure materials. Performance: Specified to deliver rated DC output power (500W or 400W) while regulating 12V output across the stated input voltage range. Use cases and applications Industrial control panels: Provide a stable 12V supply for PLCs, sensors, relays, and control modules fed from 380V mains. Battery charging and backup systems: Serve as a 12V charge power supply for leadacid or other 12V battery banks in backup or offgrid systems where the AC source is in the 323–437V range. Telecommunications, lighting, and automation: Power 12V lighting, communication equipment, or automation devices directly from a voltage AC distribution without extra converters. What to consider when selecting this unit Choose the 500W or 400W version based on the total DC load and charging requirements. Confirm that your input supply falls within the supported 323–437V range to ensure reliable regulation to 12V DC. Review the supplier's datasheet for detailed installation, mounting, connection, and environmental specifications prior to installation. Operational highlights Designed to deliver a regulated 12V DC output from AC380V inputs with tolerance for voltage variation. Provides both charging capability and generalpurpose 12V power in a single converter solution. Available in two power ratings (500W and 400W) to fit different power budgets and application demands. For modelspecific dimensions, connection diagrams, and installation guidance, refer to the product datasheet or contact the supplier.
