The Mean Well RST-15K-380 is a 15,030W three-phase AC/DC power supply delivering 380V DC at up to 39.55A. It is built for high-current industrial loads — plating, charging, heating and test systems — and units can be paralleled for greater capacity.

It accepts three-phase 196~305VAC input with a power factor above 0.98 at full load, operates from -30°C to 70°C with forced-air cooling and carries CB, CE, EAC and EN approvals, and includes constant-current limiting, over-voltage and over-temperature protection. Backed by a 5-year warranty.

Frequently Asked Questions

What applications is the Mean Well RST-15K-380 designed for?

The RST-15K-380 is intended for high-power industrial systems that need a regulated 380V DC output from a 3-phase AC source. With a 15030W power rating, it is suited to demanding OEM and commercial applications where high output power and a built-in industrial feature set are important.

What makes the RST-15K-380 suitable for high-power systems?

This model delivers 15030W of output power at 380V and 39.55A, placing it in a very high-power class. It also supports active current sharing for up to 2 units, allowing system designers to scale to as much as 28.5KW when higher capacity is required.

What input power range does the RST-15K-380 support?

The RST-15K-380 is built for 3-phase AC input. It supports 3-phase 3-wire delta input from 196 to 305VAC and 3-phase 4-wire wye input from 340 to 530VAC, making it appropriate for industrial power environments that use 3-phase service.

Can the output of the RST-15K-380 be adjusted?

Yes. This model has programmable output voltage and constant current level control, and it offers a wide voltage adjustment range from 1% to 120%. That makes it more flexible than fixed-output supplies in applications that need controlled output tuning within the product's design range.

How efficient is the Mean Well RST-15K-380?

The RST-15K-380 is rated for efficiency up to 94%. High efficiency helps reduce wasted energy and is especially valuable in high-power equipment where thermal performance and operating cost matter.

What protections are included in the RST-15K-380?

This power supply includes protection for short circuit, overload, over voltage, over temperature, and fan fail. Those built-in protections help support reliability in demanding industrial operating conditions.

What operating environment is the RST-15K-380 rated for?

The specified operating temperature range is -30°C to 70°C. The unit uses forced air cooling, which is consistent with its high-power design and supports operation across a wide industrial temperature range.

What should buyers know about the size and service life of this model?

The RST-15K-380 weighs 25 kg, which reflects its high-power enclosed industrial construction. Mean Well also backs this model with a 5-year warranty, giving buyers added confidence for long-term commercial use.
