Woehrle Schaltnetzgerät 20A 1phasig E2420AC 85-264V24VDC 41

Industrial automation and control systems demand a power source that won't quit when the line voltage sags or surges. The Woehrle 41.000000000058 switched-mode power supply delivers a rock-steady 24V DC at up to 20A, even when your mains input swings from 85 to 264V AC. That's the difference between a production line that keeps humming and one that stutters to a halt.

Who is it for

This unit is built for control cabinet builders, machine integrators, and maintenance engineers who need a compact, DIN-rail mountable power supply for PLCs, sensors, actuators, and other 24V industrial loads. If you're commissioning a new panel or replacing an aging linear supply, this SMPS offers the efficiency and reliability modern equipment expects.

Main features

• Wide-range single-phase input: 85–264V AC, 50/60 Hz – works on almost any mains supply worldwide.
• High current output: 20A at 24V DC, delivering up to 480W of clean, regulated power.
• Switched-mode design: high efficiency and low heat generation compared to linear supplies.
• Compact DIN-rail housing: saves space in crowded control cabinets and simplifies installation.
• Built-in protection: overload, short-circuit, and overvoltage safeguards protect both the supply and your load.
• Adjustable output voltage: fine-tune the output to compensate for voltage drops in long cable runs.
• Convection cooling: no fan means no noise, no dust ingress, and one less moving part to fail.

Tips

When selecting a power supply, always add at least 20% headroom over your calculated load to handle inrush currents and future expansion. For this 20A unit, keep continuous loads below 16A for optimal longevity. If you're powering inductive loads like motors or solenoids, consider adding external protection such as a diode or surge suppressor to prevent voltage spikes from feeding back into the supply.
