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 0.1uf & 47uf 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. 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)
6. The power supply is considered a component which will be installed into a final equipment. 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)
7. Only for Blank type,R type efficiency slightly less than the Blank type.
8. Inrush current parameter has 10% tolerance.
9. RCM is on voluntary basis and meets relevant IEC or AS/NZS standards complying with AS/NZS 4417.1.

FAQ

Can I use the UHP-350-24 for a 24V PLC, sensor, or industrial automation system?

Yes, this constant-voltage model delivers 24V at up to 14.6A, with 350.4W total output. That makes it a practical fit for 24V PLC systems, sensors, and general industrial automation equipment built for 24V DC.

Is the UHP-350-24 suitable for 24V control cabinets and machine control hardware?

It can be suitable for 24V control cabinets where the total DC load remains within 350.4W and 14.6A. The 220.0 × 62.0 × 31.0 mm low-profile body is also helpful where panel space is limited.

Can this model power 24V embedded systems or industrial I/O equipment?

Yes, the 24V constant-voltage output aligns with many embedded and industrial I/O systems that use a 24V DC bus. With 14.6A available, it sits above smaller 24V supplies while keeping the same slim, fanless UHP housing style.

Is the UHP-350-24 meant for outdoor environments?

The unit is specified for operation from -30°C to +70°C, but the provided specs do not include an IP rating. That means the temperature range is defined, while outdoor exposure resistance is not.

How does the UHP-350-24 compare with the other UHP-350 voltage options?

The UHP-350 series includes models from 198W to 351W with output voltages ranging from 3.3V to 55V. The UHP-350-24 provides 350.4W at 24V and 14.6A. All models in this series share the same slim, fanless design and universal input range, with the selection point mainly being the required output voltage and current.
