Artesyn NFS40 Series 40W Universal Input AC-DC Power Supply Datasheet
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.
