Test conditions and notes7

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. Please contact MEANWELL for 320~370VDC application.
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).

FAQ

What high-power 12V industrial applications can the RSP-2000-12 serve?

The RSP-2000-12 delivers 12V at 100A (1200W) and is designed for very high-current 12V bus systems such as industrial electroplating, large automation panels with many 12V actuators, 12V DC motor drive banks, and high-current data center auxiliary power. The 90–264VAC input covers worldwide single-phase supply voltages.

How does the RSP-2000-12 compare to the RSP-1500-12 and RSP-1600-12?

The RSP-1500-12 delivers 12V/125A/1500W (278 × 127 × 83.5 mm, 91% efficiency, 3+1 sharing). The RSP-1600-12 delivers 12V/125A/1500W (300 × 85 × 41 mm, 93% efficiency, 5+1 sharing). The RSP-2000-12 delivers 12V/100A/1200W (295 × 127 × 41 mm, 92% efficiency, 3+1 sharing). The RSP-2000-12 provides 1200W at 100A, slightly less total power than the RSP-1500/1600-12 at 125A.

What does the RSP-2000-12's (3+1) current sharing allow?

Active current sharing (3+1) allows three RSP-2000-12 units in parallel to deliver 300A at 12V combined, with a fourth unit as N+1 hot standby. This supports high-current fault-tolerant 12V bus design for mission-critical machinery.

What is the operating temperature range of the RSP-2000-12 and how does it differ from other RSP series?

The RSP-2000-12 operates from -35°C to +70°C ambient — the broadest cold-side rating in the RSP family, extending 5°C below the -30°C of the RSP-1600 series and 15°C below the -20°C of the RSP-1000/1500 series. This makes it suitable for very cold environments. No IP rating is specified.

What efficiency does the RSP-2000-12 achieve?

The RSP-2000-12 includes built-in active PFC and achieves up to 92% efficiency. At the rated 1200W output, input power is approximately 1304W with approximately 104W dissipated as heat, a favorable thermal load for a unit of this output class.
