Mean Well UHP-200A-4.2 Power Supply 168W 4.2V 40A

Q: What are the key output specifications of the Mean Well UHP-200A-4.2?

The UHP-200A-4.2 is rated for 168W total output power. It provides a 4.2V DC output with a rated current of 40A, which makes it a high-current, low-voltage enclosed power supply for demanding equipment.

Q: What kinds of applications is the UHP-200A-4.2 typically suited for?

This model is best suited to equipment that needs a regulated 4.2V supply and high current capacity in an enclosed AC-DC format. Its low-profile 26mm design and fanless operation make it a practical option for compact industrial or OEM builds where space and noise matter.

Q: Is the Mean Well UHP-200A-4.2 a good choice for space-constrained enclosures?

Yes. One of the main differentiators of this model is its 26mm low-profile housing, which helps when vertical space is limited inside cabinets or equipment chassis. That makes it easier to specify than bulkier enclosed supplies when mechanical clearance is tight.

Q: What operating environment is this power supply designed to handle?

The UHP-200A-4.2 is specified for operation from -30°C to 70°C. It also uses free-air convection cooling with a fanless design, which supports quieter operation and reduces reliance on active cooling components.

Q: What input and protection features does the UHP-200A-4.2 include?

This model accepts a universal AC input range of 90 to 264VAC and also supports 127 to 370VDC input. It includes built-in active PFC and protection functions for short circuit, overload, over voltage, and over temperature, which are important for long-term equipment reliability.

Q: What warranty and physical characteristics should buyers know about?

The Mean Well UHP-200A-4.2 includes a 3-year warranty. It has a listed weight of 0.42 kg, which is useful when evaluating it for compact assemblies or larger multi-unit builds.
