Yokogawa Electric Corporation F3PU20-0S Power Supply Module

The Yokogawa F3PU20-0S Power Supply Module provides a regulated 5 VDC output to the FA-M3 PLC CPU and I/O base modules, delivering stable power across Yokogawa FA-M3 systems in industrial control panels, manufacturing automation lines, and process control environments. It supports base units F3BU05, F3BU09, F3BU13, and F3BU16 for reliable power distribution across PLC racks, helping maintenance teams, OEMs, and system integrators with replacement and expansion needs. Technical specs include an input range of 100–240 V AC (single-phase, 50/60 Hz) with a rated power of 85 VA and an output of 5 V DC at 4.3 A. Inrush current is 20 A at 120 V AC and 45 A at 240 V AC (max). Mounting is base-module mounted using M4 terminal screws. Electrical isolation features include insulation resistance ≥5 MΩ at 500 V DC and dielectric strength of 1500 V AC for 1 minute. Operating temperature ranges from 0°C to 55°C in typical industrial environments. For planning spare parts, common replacements include the F3PU30-0S, F3PU26-0S, and F3PU36-0S.
