Test conditions and notes8

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. PV/PC functions when users do not use SVR.
6. 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 720mm*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)
7. 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).
8. Refer to derating curve.

FAQ

What are the main output specifications of the Mean Well UHP-1500-380?

The UHP-1500-380 is a 1500W enclosed AC-DC power supply with a 380V output. Its rated output current is 4.5A, making it a high-voltage option for applications that need substantial DC power from a slim form factor.

What makes the UHP-1500-380 different from standard enclosed power supplies?

This model stands out for its 380V high-voltage output, fanless conduction-cooled design, and slim 1U low-profile 41mm height. It is aimed at buyers who need high power density without adding fan noise or extra cooling maintenance.

Is the UHP-1500-380 a good choice for space-constrained equipment?

Yes. The unit uses a slim 1U low-profile design at 41mm, which helps in applications where vertical space is limited. That makes it easier to specify for compact industrial or enclosure-based systems that still need 1500W output capacity.

Can this power supply be used in noise-sensitive or dust-sensitive environments?

Its fanless, conduction-cooled design makes it well suited for environments where reduced acoustic noise and lower airflow-related dust intake are important. This design can be preferable in enclosed equipment or applications where fan maintenance is a concern.

What protection and control features are included on the UHP-1500-380?

This model includes protection for short circuit, overload, overvoltage, and overtemperature conditions. It also provides remote ON-OFF control, a DC OK signal, and programmable output voltage and constant current level through PV/PC functionality.

What operating environment and warranty should buyers expect for this model?

The UHP-1500-380 is rated for operation from -30°C to 70°C. Mean Well specifies a 5-year warranty for this model, which is useful for long-life commercial and industrial purchasing decisions.
