Test conditions and notes9
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 5. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
- 6. No load power consumption<0.5W when RC- & RC+ (CN100 pin1,2) 0 ~ 0.8V or short.
- 7. When the input voltage is less than 40VAC, the SPS may exhibit degradation of performance. The final product manufacturers must re-confirm this deviation that does not affect basic safety or essential performance.
- 8. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 9. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the MSP-450-5 for a high-current 5V industrial controller or I/O system?
Yes, this power supply delivers constant 5V output at up to 90A with a 450W rating. That makes it suitable for 5V industrial controllers, I/O assemblies, and other low-voltage systems with high current demand.
Is the MSP-450-5 a fit for powering multiple 5V embedded boards in a rack or cabinet?
It can be a good fit where the equipment is designed for a regulated 5V rail and the total draw stays within 90A and 450W. The 218.0 × 105.0 × 41.0 mm size also supports cabinet or rack integration where space matters.
Would this 5V model work for automated test fixtures or production electronics benches?
Yes, the MSP-450-5 is appropriate for benches or fixtures that need a constant 5V source with substantial available current. Its wide 85-264VAC input range helps when the same equipment may be used under different AC input conditions.
Can the MSP-450-5 support legacy 5V digital hardware that draws heavy current?
It is well suited to 5V digital hardware when the load requirements fall within 450W and 90A. The output profile is especially relevant for older or specialized electronics that still use a high-current 5V bus.
Is this 5V power supply intended for outdoor environments?
The product is rated to operate from -40°C to +70°C, with output derating at higher ambient temperatures per the derating curve. No IP rating is listed, which means the provided specs do not define it for outdoor or water-exposed use.
