Frequently Asked Questions
Can I use the MPS-45-48 for 48V industrial communication or control equipment?
Yes, if the equipment is designed for constant 48V DC input and draws no more than 1A or 48W. That makes it suitable for lower-power 48V industrial communication hardware, interface modules, and control devices that need a regulated 48V rail. The 90-264VAC input also supports use across a wide range of AC supply conditions.
Is this a good fit for small 48V automation loads in a control cabinet?
It can be a fit for compact 48V automation loads when the total demand stays within 1A and 48W. This is most relevant for smaller control, signaling, or communications equipment that runs from a constant-voltage 48V supply. It is not intended for loads that require more than 1A.
Can the MPS-45-48 power a 48V embedded or telecom-style device?
It can, provided the device expects 48V constant voltage and its power draw remains at or below 48W. That makes it relevant for many compact 48V embedded systems and telecom-style electronics with modest current demand. Buyers should match both the 48V output and the 1A current limit to the load requirements.
Can this power supply be used in outdoor equipment?
The operating temperature is specified as -10°C to +60°C, but no IP rating is listed. Because ingress protection is not stated, outdoor or exposed use should not be assumed from the product specs alone. It is better suited to protected indoor environments or sealed enclosures that handle dust and moisture protection separately.
How does the MPS-45-48 compare with other 48V MPS models?
The 48V MPS range includes MPS-30-48 at 28.8W and 0.6A, MPS-45-48 at 48W and 1A, MPS-65-48 at 64.8W and 1.35A, MPS-120-48 at 120W and 2.5A, and MPS-200-48 at 200W and 4.2A. All are constant-voltage 48V models, with the main differences being output current and total power. This model sits in the lower-middle of that 48V lineup.
