Application Scenarios
A medium-sized automotive component factory faced recurring downtime in its robot assembly line,caused by inconsistent power supply to the line’s I/O modules and PLCs.The factory’s existing power units struggled to handle voltage dips(from 200V to 180V AC)when nearby welding machines started,leading to I/O signal loss and robot halts.After integrating the 3AXD50000439638 into the control cabinet,the module’s wide input voltage range and stable output prevented further disruptions.The factory reported a 92%reduction in power-related downtime,as the 3AXD50000439638 maintained a steady 24V DC output even during grid fluctuations—keeping the assembly line running without interruptions.

Technical Principles and Innovative Values
Innovation Point 1:Wide Input Tolerance&Stable Output.The 3AXD50000439638 supports 100-240V AC input with±15%tolerance,a 30%wider range than standard industrial power supplies(which typically only handle±10%).This means it works reliably in regions with unstable grids(e.g.,manufacturing hubs in developing economies)and adapts to 110V/220V AC without manual adjustment.Its 24V DC output precision(±0.5V)also prevents voltage spikes that could damage sensitive I/O modules.
Innovation Point 2:High Efficiency&Low Heat Generation.With≥90%efficiency at full load,the 3AXD50000439638 generates 15-20%less heat than competitors(which average 85%efficiency).This eliminates the need for extra cooling fans in control cabinets,reducing maintenance costs and cabinet size—critical for space-constrained automation lines.
Innovation Point 3:Robust Protection&Durability.Unlike basic power supplies that only offer short-circuit protection,the 3AXD50000439638 adds overvoltage(30V DC trigger),overcurrent,and overtemperature safeguards.For example,if a downstream actuator shorts,the module cuts output in<1ms to avoid damage—extending the lifespan of connected equipment by 30%(per ABB field data).
Application Cases and Industry Value
A global food and beverage manufacturer used the ABB 3AXD50000439638 to upgrade its bottling line’s power system.The line previously relied on generic power supplies that failed frequently in the factory’s warm(up to 55°C)and humid environment,causing 1-2 hours of downtime weekly.After installing the 3AXD50000439638(which operates up to 60°C),the manufacturer saw zero power-related failures over 12 months.The module’s Modbus interface also allowed remote monitoring—technicians could check output current/voltage via the factory’s SCADA system,identifying potential issues(e.g.,a failing I/O module drawing excess current)before they caused downtime.This upgrade reduced maintenance costs by 40%and increased line productivity by 5%.
