Frequently Asked Questions
Can I use the MPM-45-48 for 48V telecom or network equipment?
It can be used for equipment that requires a constant 48V DC source and draws no more than 0.94A or 45.1W. That output profile fits many 48V IT, telecom, and communications power sections when the load stays within the rated current.
Is the MPM-45-48 a good fit for 48V industrial control or monitoring devices?
Yes, if the device expects 48V constant voltage input and its demand remains within 45.1W and 0.94A. The wide 80-264VAC input also supports use across a broad AC input range.
Can this model power 48V embedded systems or interface modules?
It is suitable for embedded or interface hardware that needs a regulated 48V output and does not exceed 0.94A. The compact 87.0 x 52.0 x 29.5 mm size can also help where internal space is limited.
Can the MPM-45-48 be used outdoors or in exposed environments?
The operating temperature range is -30°C to +80°C, so the temperature specification is broad. But the provided specs do not list an IP rating, so they do not claim weather, dust, or water ingress protection for exposed outdoor use.
What are the main differences between the MPM-45-48 and other MPM 45-series versions?
The 45-series outputs include 12V at 45W and 3.75A, 15V at 45W and 3A, 24V at 45.1W and 1.88A, 48V at 45.1W and 0.94A, and 5V at 40W and 8A. This non-ST 48V version measures 87.0 x 52.0 x 29.5 mm, while the ST 48V sibling keeps the same 45.1W, 48V, and 0.94A ratings in a 109.0 x 52.0 x 33.5 mm package.
