Test conditions and notes10

1. All parameters NOT specially mentioned are measured at △230VAC(Y 400VAC) 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. During withstand voltage and isolation resistance testing, the screw "A" shall be temporarily removed, and shall be installed back after the testing.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. If use PV signal to adjust Vo, under creatin operation conditions, ripple noise of Vo might go over rating defined in this specification.
7. The efficiency is measured at △: 230VAC/Y: 400VAC input. The efficiency level is measured at output voltage 115V(115V model)/230V(230V model)/380V(380V model).
8. The power supply is considered a componenr which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 600mm*900mm 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).
10. An unstable O/P voltage is expected in the first 300ms after power on. A minimum load of 5% is suggested if fast load change is required at power on phase.

FAQ

What are the main electrical ratings of the Mean Well RST-7K5-380L?

The RST-7K5-380L is a high power AC/DC power supply rated for 7515W output. It provides a nominal 380V DC output with a rated current of 19.77A. This model is designed for 3-phase input power.

What types of applications is the RST-7K5-380L suited for?

This model is intended for high power industrial and commercial systems that need a regulated 380V DC supply. Its 7515W rating, programmable output characteristics, and current sharing capability make it relevant for demanding B2B equipment environments. Buyers typically consider this class of power supply where high output power and scalable system capacity are priorities.

Does the RST-7K5-380L support higher-capacity systems?

Yes. The unit supports active current sharing for up to 4 units, allowing total output capacity up to 28.5KW. That makes it suitable for applications that may need scalable power architecture using multiple matched supplies.

What cooling options are available on the RST-7K5-380L?

The RST-7K5-380L offers selectable cooling methods: forced air cooling (blank type) or water cooling (L type). This gives buyers flexibility when evaluating thermal management for high power enclosures or industrial systems. The model also includes fan fail protection as part of its protection set.

Can the output be adjusted on this power supply?

Yes. The output voltage and constant current level are programmable, and the voltage adjustment range is specified as 1 to 120%. This is useful for applications that need controlled output behavior within the model's supported range.

What operating environment is this model designed for?

This power supply is rated for operation from -30°C to +70°C. That wide temperature range makes it appropriate for demanding industrial environments, provided the overall system design stays within the product's operating limits. The unit itself weighs approximately 10.9 kg (forced air) or 10.1 kg (water cooled), which also reflects its heavy-duty high power construction.

How does the RST-7K5-380L differ from lower-power enclosed AC/DC power supplies?

The RST-7K5-380L stands out with its 7515W output capacity, 380V output, and 3-phase input requirement. Compared with lower-power enclosed supplies, it is built for substantially higher power demand and includes features such as programmable output control, selectable cooling (forced air or water), and active current sharing. Those characteristics make it a better fit for large-scale industrial power applications rather than general low-to-medium power use.

What protection and support features are included with the RST-7K5-380L?

This model includes protection for short circuit, overload, over voltage, over temperature, and fan fail conditions. It also provides remote ON-OFF control and an alarm signal for system-level monitoring. Mean Well specifies a 5-year warranty for this power supply.
