Napájací zdroj/invertor MEAN WELL PSPA-1000-24, 1000 W, 24 V výstup, 90–264 V vstup

MEAN WELL PSPA-1000-24 is a compact 1000 W power adapter and inverter that provides a regulated 24 V DC output from a wide AC input range of 90–264 V. The unit measures 120 × 170 × 93 mm and is designed for enclosed mounting in industrial and commercial installations where a stable 24 V supply is required. The device integrates power factor correction and supports parallel operation for capacity expansion, along with remote ON/OFF and DC OK signalling for system control and monitoring.

Advantages

The PSPA-1000-24 offers high power density in a compact housing, enabling installation in space-constrained control cabinets. Built-in power factor correction improves AC usage efficiency while parallel function allows multiple units to be combined for higher output currents or redundancy. Remote ON/OFF and a dedicated DC OK signal simplify integration with supervisory systems. Compliance with RoHS and an enclosed design reduce installation risk in industrial environments.

Suitable for

• Industrial control panels and automation equipment requiring 24 V DC
• Commercial backup power systems and UPS-related applications
• Equipment testing benches and development labs

How to use

Install the PSPA-1000-24 in a suitable enclosed cabinet or on a stable surface with adequate ventilation. Connect the AC supply within the specified 90–264 V range and verify proper grounding. Make DC output connections to the load using appropriate cable cross-section for the maximum 42 A current and secure terminals to prevent contact resistance. Use the remote ON/OFF terminals to integrate with control logic and monitor the DC OK signal for system status. When paralleling units, follow manufacturer guidance for current sharing and equalization to ensure balanced operation.

Recommendations

To ensure reliable operation, provide adequate ventilation clearance and avoid mounting near heat sources. Use appropriately rated fuses or circuit breakers on both AC and DC sides, and select cables with suitable temperature and current ratings. For parallel configurations, match units of the same model and specifications, and perform commissioning checks on current sharing and DC OK signalling before putting systems into continuous operation.
