Frequently Asked Questions

Can I use the MPM-45-48ST for 48V automation or control equipment?

Yes, if the equipment requires a constant 48V DC output and its load stays within 45.1W and 0.94A. That makes it relevant for 48V industrial control, instrumentation, and automation subsystems that match those limits.

Is the MPM-45-48ST suitable for 48V communications or telecom hardware?

It can support 48V communications hardware that operates from a constant voltage source and draws no more than 0.94A. The unit also accepts 80-264VAC input, which is useful where AC input conditions vary.

Can this power supply be used in compact 48V embedded equipment?

It can be used in embedded equipment that needs 48V DC and remains within the 45.1W output rating. This ST version is larger than the non-ST model at 109.0 x 52.0 x 33.5 mm, so enclosure space should be checked against those dimensions.

Is the MPM-45-48ST suited for cold or hot operating conditions?

Its specified operating temperature range is -30°C to +80°C, which supports use across a wide temperature window. The provided specs do not include an IP rating, so the temperature range alone does not confirm suitability for wet or dusty outdoor exposure.

How does the MPM-45-48ST fit within the MPM 45-series lineup?

The MPM 45-series includes 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 model is the ST version of the 48V option, and its non-ST sibling keeps the same electrical ratings in a smaller 87.0 x 52.0 x 29.5 mm body.
