Frequently Asked Questions
Can I use the MPM-90-48ST in a 48V industrial or embedded system?
Yes, if the equipment is designed for a 48V constant voltage input and stays within 90.2W and 1.88A. That makes it relevant for 48V industrial, embedded, and automation equipment that needs a fixed 48V DC rail. It is not interchangeable with 12V, 15V, or 24V versions unless the load is built for 48V.
Is the MPM-90-48ST appropriate for medical or low-leakage electronic equipment using 48V DC?
The product is listed as medical safety approved and features extremely low leakage current, which can matter in medical and sensitive electronic designs. Electrically, it provides 48V constant voltage output up to 90.2W and 1.88A. The equipment still needs to be specified for a 48V input rail.
Can this model support a larger 48V load than the smaller MPM 48V supplies?
It is the highest-power 48V option shown in the listed family, with 90.2W and 1.88A output. That gives it more available capacity than the 30.2W, 45.1W, and 65.3W 48V variants. For buyers comparing 48V options, this model is aimed at loads that need the full 90.2W class.
Is the MPM-90-48ST suitable for outdoor or temperature-extreme operation?
The operating temperature range is specified as -30C to +80C, so the product data supports use across a wide temperature range. It is also encapsulated, but no IP rating is listed in the provided specs. Without an IP rating, the published data does not confirm outdoor or direct weather exposure suitability.
What is the difference between the MPM-90-48ST and the other 48V siblings in the series?
The listed 48V models are MPM-30-48 and MPM-30-48ST at 30.2W and 0.63A, MPM-45-48 and MPM-45-48ST at 45.1W and 0.94A, MPM-65-48 and MPM-65-48ST at 65.3W and 1.36A, and MPM-90-48 at 90.2W and 1.88A. The MPM-90-48ST is the ST version at 90.2W and 1.88A, with published dimensions of 109.0 x 52.0 x 33.5 mm and weight of 0.219 kg.
