Key benefits Reliable 48V output from varying 48V battery sources: maintains a stable 48VDC rail when input voltage varies between 42V and 57VDC, solving common under and overvoltage issues in 48V systems. Flexible power options: available in 400W and 500W power ratings to match system demand and reduce overspecification. Versatile conversion modes: functions as a charge power supply and supports both DCDC boost and buck conversion, allowing stepup or stepdown regulation as needed. Simplifies system design: combines regulation and charging capability in a single unit so you can avoid separate converters or chargers. Key attributes Input voltage: 48V nominal, accepts 42–57VDC input range. Output voltage: regulated 48VDC. Power ratings: available in 400W and 500W configurations. Functionality: charge power supply, DCDC boost and buck converter; also described as ACDC converter compatible with charging applications. Use case compatibility: designed for systems that require a stable 48VDC bus and charging capability from a 42–57V source. How it solves problems Keeps sensitive 48V electronics operating reliably when battery voltage falls under load or when sources vary, reducing equipment resets and downtime. Eliminates the need for multiple components by providing power conversion and charge supply functions in one device. Scales to application power needs with two wattage options, helping control cost and thermal considerations. Practical applications Telecom and network cabinets: provide a stable 48VDC supply and battery charging for routers, switches, and remote radio heads where battery voltage can vary during discharge and recharge cycles. Renewable energy and battery storage systems: regulate fluctuating battery or DC bus voltages from solar charge controllers or battery arrays and supply a consistent 48V rail for inverters, controllers, or charging loads. Industrial and mobile equipment: power 48V control systems, electric vehicle auxiliary systems, or charging circuits for 48V battery packs in material handling, ebikes, or light electric vehicles. What to consider when selecting Choose the 400W model for lighter loads and lower heat generation; choose the 500W model when higher continuous power is required. Verify your system's input nominal voltage falls within the 42–57VDC window to ensure correct operation. Confirm mounting, cooling, and environmental requirements in your installation (sitespecific details should be checked against supplier documentation). Why customers choose this product Direct compatibility with common 48V battery systems and the ability to regulate across a realistic battery voltage range. Singleunit solution for powering and charging tasks where a stable 48V output is essential. Clear power options (400W or 500W) to match application needs without unnecessary oversizing. For installation, configuration, and safety details, refer to the manufacturer's technical documentation and wiring instructions to ensure proper integration with your 48V system.
