Frequently Asked Questions
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.
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.
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.
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.
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.
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.
