Frequently Asked Questions
What applications is the Mean Well UHP-200A-4.5 best suited for?
This model is designed for equipment that specifically requires a 4.5V DC supply with up to 40A of output current. It is a practical fit for OEM, industrial, and security-related systems where high current, low voltage, and a compact enclosed power supply are important. Buyers should match it to loads that are specified for 4.5V operation.
What are the key output specifications of the UHP-200A-4.5?
The UHP-200A-4.5 is rated for 180W total output power with a 4.5V DC output and 40A rated current. That makes it a high-current option for low-voltage applications that cannot use more common 12V or 24V supplies. The model name and rating are aligned around that 4.5V output class.
What AC input range does this power supply support?
This model supports a universal input range of 90 to 264VAC, and it also accepts 127 to 370VDC. That wide range makes it easier to standardize across projects that may operate in different mains environments. It also withstands a 300VAC surge input for 5 seconds.
How does the UHP-200A-4.5 handle cooling in compact installations?
The UHP-200A-4.5 uses a fanless design and cools by free air convection. It also has a low-profile 26mm form factor, which helps when space is limited inside equipment housings. For buyers trying to avoid fan noise and moving parts, that is a meaningful advantage.
What protection features are built into this model?
This power supply includes protection for short circuit, overload, over voltage, and over temperature. Those built-in safeguards make it better suited for professional equipment where power stability and fault response matter. It also includes an LED indicator for power-on status.
Is the UHP-200A-4.5 suitable for wider temperature ranges?
This model is specified for operation from -30°C to 70°C. That range makes it more suitable than many general-purpose indoor-only supplies for demanding commercial or industrial environments. Its fanless convection design also avoids reliance on active cooling hardware.
What warranty and physical characteristics should buyers know about?
The UHP-200A-4.5 carries a 3-year warranty from Mean Well. It weighs approximately 0.42 kg, which supports use in compact equipment designs where lower mass can be helpful. Its slim 26mm profile is one of the main physical differentiators of this series.
