Power inverter MEAN WELL CSP-3000-120, 3000 W, input 180–264 V, output 120 V, 177.8×278×63.5 mm

MEAN WELL CSP-3000-120 is a 3000 W inverter/adapter designed to provide a stable 120 V AC output from a wide AC input range of 180–264 V. Housed in a compact metal enclosure with dimensions 177.8×278×63.5 mm, the unit integrates PFC and an AC-DC single output topology delivering 120 Vdc at 25 A with remote ON/OFF control. The product meets RoHS requirements and is intended for applications that require continuous high-power AC or DC supply with a compact footprint.

Advantages

The CSP-3000-120 offers a high continuous power rating of 3000 W in a compact metal housing, allowing installation in constrained spaces. Built-in power factor correction improves input efficiency and reduces reactive current. Remote ON/OFF control enables integration with external control systems or automated power management. Compliance with RoHS ensures the design follows environmental and material safety guidelines.

How to use

Install the inverter on a flat surface or inside a ventilation-enabled cabinet, ensuring adequate airflow around the metal housing. Connect the AC input to a 180–264 V supply following local electrical codes and ensure proper grounding. Connect the 120 V output to the load, observing the maximum continuous current rating of 25 A. Use the remote ON/OFF terminals to integrate with external control circuits or automation systems. Verify polarity and connections before powering on and monitor the device during initial startup for correct operation.

Recommendations

For reliable operation, allow at least 20 mm clearance around the unit for ventilation, avoid mounting near heat sources, and use appropriately rated wiring and protective devices sized for 3000 W continuous load. Periodically inspect terminals and cooling paths for dust build-up and ensure the remote control wiring is free from electrical noise to prevent unintended switching.
