The NFS40 series is a 40 W universal input ac-dc power supply on a 5" x 3" card with a maximum component height of 1.2" for use in 1U applications. The NFS40 series is available with a wide range of models in the industry standard 5" x 3" footprint and has proven itself to be highly reliable and versatile product for a wide range of communication and industrial applications. The NFS40 provides 40 W of output power with free air convection cooling which can be boosted to 50 W with 20 CFM of air. Standard features include OVP and short-circuit protection. The series, with full international safety approval and the CE mark, meets conducted noise EN55022 level A. The NFS40 series is designed for use in low power data networking, computer, telecom and industrial applications such as hubs, routers, POS terminals, cable modems, PABX's, industrial PC's and machine control.
The NFS40 series provides 40 W of output power with natural convection cooling and can be boosted to 50 W using 20 CFM forced air. It is available in single‑output and triple‑output configurations and meets EN55022 Level A conducted noise requirements. Standard features include over‑voltage protection, short‑circuit protection, and full international safety approvals (UL, VDE, CSA, CE).
Designed for low‑power data networking, telecom, POS terminals, and industrial PC applications, the module operates from a universal input range of 85‑264 Vac (120‑370 Vdc). It supports operation from –40 °C to +85 °C (non‑operating) and includes mechanical mounting options with non‑metallic stand‑offs and optional cover kits.
