The Mean Well USA KNX-40E-1280 is a single-output AC/DC DIN Rail power supply delivering a nominal 30V DC at 1.28A, with a total power capacity of 38W. Designed for industrial and commercial use, it accepts a wide AC input voltage range of 180 to 264 VAC and also supports a DC input of 176V (note: the DC value is unconfirmed). The unit achieves up to 86% efficiency, minimizing heat dissipation.
Electrical isolation is rated at 4.2 kV between input and output, providing robust safety margins. The operating temperature range is -30°C to 70°C, with derating required at higher temperatures. The supply is housed in a compact DIN Rail enclosure measuring 72.0mm x 58.5mm x 90.0mm and features an IP20 ingress protection rating.
This power supply is CE approved and intended for ITE (Commercial) applications. It is RoHS3 compliant, though this status is unverified. The KNX-40E-1280 is suitable for powering sensors, relays, controllers, and other equipment in industrial automation, building management, and panel building environments.
