MEAN WELL RSP-200-48 201,6W 48V 1U Alimentatore a basso profilo con custodia chiusa con PFC attivo e raffreddamento a ventola

Industrial and automation systems often demand a power source that combines high efficiency, compact dimensions, and unwavering reliability. The MEAN WELL RSP-200-48 answers that call with a 201.6W output in a 1U low-profile form factor, engineered for seamless integration into space-constrained equipment racks and control cabinets. Its 48V DC output at 4.2A is ideal for powering motors, sensors, PLCs, and other 48V-based devices, while active power factor correction ensures compliance with global energy standards and reduces harmonic distortion on the AC mains.

Who is it for

This power supply is built for system integrators, machine builders, and maintenance professionals who need a dependable 48V rail in factory automation, test and measurement, LED lighting, or telecommunications. It is equally suited for OEM applications where a slim 1U profile is a prerequisite, and for retrofitting existing installations that require a high-efficiency upgrade without sacrificing reliability.

Tips

To maximize service life, ensure adequate ventilation around the unit and keep the fan intake free from dust. For 48V DC input applications, verify polarity and use appropriate fusing. Mount the supply with screws on all four corners to prevent vibration-induced stress. When connecting multiple units in parallel, consult the datasheet for current sharing guidelines.
