Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. In the PV Mode: 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. Turn off the output when input voltage is less than 160VAC.
5. 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)
6. 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 is the CSP-3000-400 typically used for?

The Mean Well CSP-3000-400 is typically used in very high-voltage DC applications that need a single-output 3000W enclosed power supply. With 400V output at 7.5A, it is aimed at specialized industrial and high-voltage DC systems that are designed around a 400V output class.

Is the CSP-3000-400 suitable for large 400V DC loads?

Yes. The CSP-3000-400 delivers 3000W at 400V and 7.5A, making it suitable for high-voltage DC applications that need substantially more power and a higher output class than standard low-voltage enclosed supplies.

Can the CSP-3000-400 be used in systems that require output programmability?

Yes. The product features list programmable output voltage and current, so the CSP-3000-400 is relevant for applications that need a configurable high-power DC source rather than a fixed-output-only platform.

Does the CSP-3000-400 support multi-unit scaling for larger systems?

Yes. Up to 3 units can be connected in parallel with the built-in active current sharing function, which means the CSP-3000-400 is designed for larger architectures where multiple units may be combined to extend total power capacity (total output current limited to rated current × number of units × 0.9).

What AC input range does the CSP-3000-400 use?

The specified AC input range is 180-264VAC, with 254-370VDC also listed. That makes the CSP-3000-400 suitable for 230V-class AC mains environments and other installations within those published input ranges.

Is the CSP-3000-400 intended for direct outdoor exposure?

The current product data does not show a waterproof IP rating, so the CSP-3000-400 should be used in a protected indoor or enclosure-based environment rather than direct outdoor exposure. Its working temperature is listed as -20°C to +65°C (refer to the derating curve), but enclosure protection is still required.

How does the CSP-3000-400 compare with the other CSP-3000 voltage options?

The CSP-3000-400 provides 3000W at 400V and 7.5A. In the same family, the CSP-3000-120 provides 120V at 25A and the CSP-3000-250 provides 250V at 12A. The best choice depends on the DC voltage class your system requires and the corresponding current profile.

What published premium features support the CSP-3000-400 in high-end power systems?

Published features include PFC (PF≥0.95 at 230VAC), 93% typical efficiency, programmable output voltage and current, parallel operation of up to 3 units with built-in active current sharing, remote ON-OFF control, 12V/0.4A auxiliary power and a Power OK signal. Listed protections include short circuit, overload, over-voltage and over-temperature, and a status LED indicates fan faults.
