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 core electrical ratings of the Mean Well RST-7K5-115L?

The RST-7K5-115L is a high power AC/DC supply rated for 7475W output. It provides 115V DC nominal output with 65A rated current. This model is designed for 3-phase AC input systems and is built for applications that need substantial regulated DC power from a single enclosure.

What types of applications is the RST-7K5-115L typically suited for?

This model fits industrial and OEM systems that need a high power 115V DC source, especially where centralized DC power is preferred over multiple smaller supplies. Its 7475W capacity, programmable output behavior, and support for parallel current sharing make it relevant for demanding equipment, test systems, and large control platforms. Buyers evaluating high-load B2B projects will usually consider it where both power density and output control matter.

Can the RST-7K5-115L be used in higher-capacity parallel power systems?

Yes. Mean Well specifies active current sharing for up to 4 units, allowing total capacity up to 28.5KW in multi-unit systems. That makes this model a practical option for larger installations that may need scalable DC power without changing to a different platform.

How does the RST-7K5-115L differ from a standard lower-power enclosed power supply?

The main difference is scale and control. This model delivers 7475W at 115V with 3-phase input support, programmable output voltage and constant current level, and selectable water or forced-air cooling. It is intended for substantially heavier-duty use than conventional single-phase or lower-wattage enclosed supplies.

What operating environment is this power supply designed for?

The RST-7K5-115L is specified for operation from -30°C to 70°C, which supports demanding industrial environments when the system is designed around the unit's cooling method. The L-type model uses water cooling, while the standard model uses forced-air cooling, giving flexibility for high thermal load installations. For buyers comparing platforms, that combination is a key differentiator in continuous-duty applications.

Does the RST-7K5-115L offer output adjustment and remote control features?

Yes. This model includes programmable output voltage and programmable constant current level, with a wide voltage adjustment range of 1 to 120%. It also has built-in remote ON-OFF control and an alarm signal, which is useful for monitored industrial power systems.

What protection and reliability features are included on the RST-7K5-115L?

Mean Well lists short circuit, overload, over voltage, over temperature, and fan fail protection for this model. The unit also carries a 5-year warranty, which is notable for a power supply in this output class. These features make it better aligned with long-service B2B equipment requirements than bare-bones high-power supplies.
