Frequently Asked Questions
Can I use the MPM-45-12ST for a 12V industrial control board or compact automation assembly?
Yes, if the load needs constant voltage 12V and stays at or below 45W and 3.75A. It accepts 80-264VAC input, which supports a broad AC input range for panel-based equipment.
Is the MPM-45-12ST a fit for 12V embedded systems that need medical safety approval?
It can be considered for 12V embedded equipment where the listed medical safety approved feature is relevant, provided the load remains within 45W and 3.75A. The output is constant voltage, so it is intended for devices designed for a regulated 12V input.
Can this model power a 12V networking, gateway, or monitoring device in an equipment enclosure?
It can support 12V gateway, monitoring, or communications hardware if the total demand does not exceed 3.75A and 45W. The encapsulated construction and less than 0.1W no-load power consumption may be useful in continuously energized enclosures.
Is the MPM-45-12ST meant for outdoor use or wide-temperature indoor environments?
Its specified operating range is -30°C to +80°C, which supports use across a broad temperature range. However, no IP rating is listed, so outdoor suitability cannot be confirmed from the provided specifications.
What is the difference between the MPM-45-12ST and the other 45W MPM power supplies?
The 45W group includes MPM-45-12 and MPM-45-12ST at 45W, 12V, 3.75A; MPM-45-15 and MPM-45-15ST at 45W, 15V, 3A; MPM-45-24 and MPM-45-24ST at 45.1W, 24V, 1.88A; MPM-45-48 and MPM-45-48ST at 45.1W, 48V, 0.94A; and MPM-45-5 and MPM-45-5ST at 40W, 5V, 8A. For this ST version specifically, the listed dimensions are 109.0 x 52.0 x 33.5 mm and the weight is 0.206 kg.
