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 component 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 applications is the Mean Well RST-15K-115 designed for?

The RST-15K-115 is a high power AC/DC enclosed power supply intended for demanding industrial and commercial systems that need a regulated 115V DC output. With a 14,950W power rating and 130A rated current, it fits applications where high output capacity and three-phase AC input are important selection criteria.

What are the key electrical ratings of the RST-15K-115?

This model is rated for 14,950W total output power with a nominal 115V output and 130A rated current. It accepts three-phase input, supporting 3-phase 3-wire 196 to 305VAC or 3-phase 4-wire 340 to 530VAC as listed in the product specification.

Does the RST-15K-115 support output adjustment or programmable control?

Yes. The product description states that the output voltage and constant current level are programmable, and it also notes a wide voltage adjustment range of 1 to 120%. That makes this model more flexible than fixed-output high power supplies when an application needs controlled adjustment within the unit's specified range.

Can this power supply be used in higher-capacity parallel power systems?

Yes. The RST-15K-115 supports active current sharing for up to 2 units, allowing a combined capacity of up to 28.5kW according to the listed features. Buyers evaluating scalability often use this as a key differentiator when comparing high power supply options.

What environmental operating range does the RST-15K-115 support?

This model is specified for operation from -30°C to 70°C. It also uses forced air cooling, which is relevant for higher power applications where thermal performance is an important consideration.

What protection features are included in the Mean Well RST-15K-115?

The RST-15K-115 includes protection for short circuit, overload, over voltage, over temperature, and fan fail conditions. These built-in protections are important for industrial buyers looking to reduce risk in high power DC systems.

How efficient is the RST-15K-115, and what warranty does it include?

The listed efficiency is up to 94%, which is notable for a 14.95kW AC/DC power supply in this class. Mean Well also specifies a 5-year warranty for this model.
