This Power Supply PSU Driver Transformer accepts a universal mains input and delivers a 36V output with up to 400W of power. It is designed for quiet operation and uses a single fan to maintain cooling while minimizing noise in workspaces or installations. The unit provides a versatile solution for 36V needs in environments that use 110V or 220V mains. Key features and benefits Universal input range: 110V to 220V with a tolerance of plus or minus 15 percent, enabling use in multiple regions without a separate power adapter. 36V output: Suitable for powering 36V loads in electronics projects, control systems, or compatible equipment. power capability: Up to 400W of output to support demanding devices and applications. Quiet operation: One built in fan designed to minimize noise during operation. Practical PSU and driver transformer functionality: Combines power supply and transformer features in a single module for streamlined integration. Key attributes Functionality: Converts mains voltage to a stable 36V output for load devices. Compatibility: Designed for use with 110V220V mains; compatible in regions with different standard voltages due to ±15% tolerance. Size and construction: Integral power supply solution suitable for installation where a single unit is preferred. Performance: Delivers up to 400W of output while maintaining quiet cooling with a dedicated fan. Applications and use cases Powering 36V electronic devices or subsystems in a workshop, lab, or development environment. Replacing or upgrading the PSU in equipment that operates from 110V220V mains and requires a 36V supply. Prototyping, testing, and development setups that need a reliable 36V power source with quiet operation. Notes This description reflects the product's stated specifications: input 110V220V ±15%, output 36V, 400W, and quiet operation with 1 fan. No additional features beyond those listed are described.
