The NXF1 is offered with input and output voltage combinations of 3.3 V and 5 V. The NXF1 series is designed for compliance with the widely accepted UL60950 safety standard with reinforced insulation to a working voltage of 125 V_RMS, with recognition currently pending. The NXF1 series is pending recognition by Underwriters Laboratories (UL) to ANSI/AAMI ES60601-1 and provides 2 MOOP (Means of Operator Protection) and 1 MOPP (Means of Patient Protection). The NXF1 series operates over the very wide industrial temperature range of -40°C to +105°C, supporting operation in still air for the most demanding environments. All models deliver full power to +85°C. Above this temperature, the output power derates, with the units continuing to operate to temperatures of up to +105°C.
