Frequently Asked Questions
Can I use the MSP-300-3.3 for a 3.3V logic or processor rail in embedded equipment?
Yes, this model provides constant voltage 3.3V output rated at 198W and 60A. It is appropriate for high-current 3.3V embedded loads that require a regulated low-voltage rail.
Is the MSP-300-3.3 suitable for FPGA, memory, or backplane-style 3.3V loads?
It can be used where the equipment needs a stable 3.3V supply and the total demand stays within 198W and 60A. The high current capacity is the main characteristic that distinguishes this version from the higher-voltage MSP-300 models.
Can this unit support a 3.3V industrial controller or communications board assembly?
Yes, if the system is designed for constant voltage 3.3V input and remains within 60A and 198W. It also accepts 85-264VAC input, which helps when the AC source varies across installations.
Is the MSP-300-3.3 intended for outdoor use?
The operating temperature range is -40°C to +70°C, but no IP rating is listed in the provided specifications. Based on that information, temperature tolerance is defined, while outdoor exposure protection is not.
How does the MSP-300-3.3 compare with the rest of the MSP-300 range?
In the MSP-300 lineup, the outputs are MSP-300-3.3 at 198W, 3.3V, 60A; MSP-300-5 at 300W, 5V, 60A; MSP-300-7.5 at 300W, 7.5V, 40A; MSP-300-12 at 324W, 12V, 27A; MSP-300-15 at 330W, 15V, 22A; MSP-300-24 at 336W, 24V, 14A; MSP-300-36 at 324W, 36V, 9A; and MSP-300-48 at 336W, 48V, 7A. This version is the lowest-voltage option and one of the highest-current options in that group.
