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-3000-250 typically used for?

The Mean Well CSP-3000-250 is typically used in high-power 250V DC applications that need a single-output 3000W enclosed power supply. With 250V output at 12A, it is intended for demanding industrial and specialized high-voltage DC systems rather than low-voltage general-purpose loads.

Is the CSP-3000-250 suitable for large high-voltage DC loads?

Yes. The CSP-3000-250 provides 3000W at 250V and 12A, which makes it suitable for heavy-duty high-voltage DC applications that need substantially more power than lower-wattage enclosed supplies can deliver.

Can the CSP-3000-250 be used in systems that need adjustable output behavior?

Yes. The published features list programmable output voltage and current, so the CSP-3000-250 is relevant for applications that need a more configurable high-power DC source instead of a strictly fixed-output platform.

Does the CSP-3000-250 support larger-capacity multi-unit systems?

Yes. Up to 3 units can be connected in parallel with the built-in active current sharing function, which makes the CSP-3000-250 suitable for larger system architectures where multiple units may be combined to increase total output capacity (total output current limited to rated current × number of units × 0.9).

What AC input range does the CSP-3000-250 support?

The specified AC input range is 180-264VAC, with 254-370VDC also listed. That makes the CSP-3000-250 appropriate for 230V-class AC mains environments and other installations that fall within those published ranges.

Is the CSP-3000-250 intended for exposed outdoor installation?

The current product data does not list a waterproof IP rating, so the CSP-3000-250 should be installed in a protected indoor or cabinet environment rather than directly exposed outdoor conditions. 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-3000-250 compare with CSP-3000-120 and CSP-3000-400?

All three models are in the 3000W CSP family, but they target different output voltage classes. The CSP-3000-120 provides 120V at 25A, the CSP-3000-250 provides 250V at 12A, and the CSP-3000-400 provides 400V at 7.5A. The right choice depends primarily on the DC output voltage your system is designed to use.

What published high-end features does the CSP-3000-250 include?

The published features include PFC (PF≥0.95 at 230VAC), 92.5% 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.
