A Weidmüller power supply is an industrial-grade DIN rail-mounted power supply that converts AC mains power to regulated DC voltage — typically 24 VDC — to power PLCs, sensors, actuators, relays, and other control devices. These power supplies are known for: High reliability Compact size Energy efficiency Long service life in harsh environments 🔧 Key Product Series 🔸 PROeco Series – Cost-effective standard applications Economical, compact, efficient 24 VDC outputs, from 1.25 A to 20 A Up to 93% efficiency LED diagnostics Wide input range: 85–264 V AC / 90–375 V DC Short-circuit, overload, overvoltage protection 🔹 PROmax Series – High-performance, demanding applications For dynamic loads, high inrush currents Output: 24 VDC (also 12 V, 48 V models) 110%–150% boost mode Operating temp: -25 to +70°C Remote monitoring via DC OK signal Ideal for machine building, process control 🟢 PROtop Series – Premium, future-proof with communication Advanced communication-enabled power supply IO-Link, CANopen, and EtherNet/IP support Hot-swappable, parallel operation, energy-efficient Optional UPS (Uninterruptible Power Supply) integration Predictive maintenance with integrated diagnostics 🔸 CP Series – Space-saving compact power supplies Slim design for control panels Output: 24 VDC, 1.25 A–10 A High MTBF (Mean Time Between Failures) Low standby losses ⚙️ General Features Feature Description Output Voltage 24 VDC (most common), also 12 VDC, 48 VDC Input Voltage Range 85–264 VAC / 90–375 VDC Power Range From 30 W to 960 W Efficiency Up to 95% Mounting DIN rail Certifications CE, UL, CSA, ATEX, IECEx (depending on model) Protection Overvoltage, overload, short circuit, thermal 🔌 Communication (PROtop Series) Supports: IO-Link for real-time monitoring EtherNet/IP for integration with PLCs CANopen for decentralized systems Enables: Energy usage tracking Predictive maintenance (e.g., capacitor aging, temperature) Remote diagnostics 🔋 UPS & Redundancy Options Weidmüller offers accessories for: UPS modules (battery-backed DC power during outages) Redundancy modules to ensure uninterrupted power from dual sources Buffer modules to bridge short-term power losses (few ms–s) 🏭 Typical Applications Sector Use Case Industrial Automation Powering PLCs, HMIs, sensors, actuators Machine Building For motors, I/O modules, safety circuits Process Control SCADA panels, instrumentation loops Renewables Wind turbines, solar plant controllers Transportation Railway signaling, control cabinets 📦 Example – PROmax 240W 24V 10A Parameter Value Input Voltage 100–240 V AC Output 24 V DC / 10 A Efficiency 93.7% Boost 150% for 4 seconds Size 70 × 125 × 125 mm Mounting DIN Rail Operating Temp -25 to +70°C 🧰 Installation & Diagnostics Tool-free DIN rail installation Status LEDs: DC OK Overload / Short Circuit Some models include relay contacts or remote monitoring outputs Maintenance-free for years in most environments 📊 Selection Tips When selecting a Weidmüller power supply: Total current load → Add up the current of all devices. Buffer or redundancy needed? Environmental conditions → Check temperature, dust, vibration. Communication required? → Go with PROtop for smart connectivity. Panel space → Choose compact models if space is tight.
