Power supply HiSmart NPF-240-12 12V 20A switching power supply

HiSmart NPF-240-12 is a 12 V DC switching power supply that delivers up to 20 A (240 W) for LED systems, CCTV equipment, routers and other 12 V devices. The unit features a compact IP67-rated enclosure suitable for indoor or outdoor installation, built-in power factor correction (PFC) and protections against short circuit, overload, over-voltage and over-temperature to ensure stable continuous operation.

Advantages

The power supply provides high efficiency (90%) and low ripple and noise (150 mV p-p) for stable 12 V output. Its PFC improves mains compatibility and the IP67 design allows use in damp or dusty environments. Thermal design uses free air convection cooling, while multiple protection circuits increase reliability in continuous or demanding applications.

How to use

Mount the HiSmart NPF-240-12 in a location that meets the IP67 installation requirements and provides adequate clearance for convection cooling. Connect the AC input within the specified 90–264 V range and observe correct polarity when connecting DC 12 V outputs to your devices. Ensure wiring and connectors are rated for the 20 A output. After connection, power on and verify stable 12 V output before connecting sensitive loads.

Usage recommendations

For reliable long-term operation, avoid covering the unit or placing it near heat sources. Use appropriately sized cables and fuses for the 20 A output and ensure outdoor installations maintain IP67 sealing. Regularly check connections and ambient temperature to prevent overheating.
