The NTQ123 Series from Emerson Network Power delivers 70 W (convection cooled) to 120 W (forced‑air cooled) output power with active power‑factor correction and remote‑sense capability. Key electrical specs include an input range of 85‑264 VAC, 47‑63 Hz frequency, 38 A inrush current, 65 % typical efficiency, and a 0.99 power factor.
The series meets multiple safety and EMC standards (UL, CSA, CE, EN‑61000‑3‑2, etc.) and operates from 0 °C to 50 °C (storage –40 °C to 85 °C). Pin assignments and connector details are provided for both power and control signals, and the unit includes overload, short‑circuit, and thermal protection features.
