Frequently Asked Questions
Can I use the MPT-45B for equipment that needs 5V, 12V, and -12V outputs?
Yes, this model is listed with 5V, 12V, and -12V outputs for multi-rail applications. Its main listed output is 5V at 3A, and the total rated power is 42.6W.
Is the MPT-45B a good fit for embedded or industrial electronics with a negative 12V rail?
It can be used where a system needs a 5V main rail plus 12V and -12V outputs from one power supply. The product is specified for 42.6W total power and 3A on the listed 5V output.
Can the MPT-45B support mixed-signal or interface boards that use both positive and negative rails?
Yes, the listed outputs of 5V, 12V, and -12V make it relevant for electronics that require both positive and negative DC rails. It is a constant-voltage power supply with 90-264VAC input.
Is the MPT-45B suitable for outdoor or high-exposure environments?
The defined operating temperature range is -10°C to +60°C. The provided specs do not include an IP rating, so the product data does not specify outdoor, wet, or dust-tight use.
What is the difference between the MPT-45A and MPT-45B?
MPT-45A is listed at 40.5W with outputs of 5V, 12V, and -5V, while MPT-45B is 42.6W with outputs of 5V, 12V, and -12V. Both list a 5V main output at 3A, but they differ in total rated power and negative output rail.
