Feature → Business Impact → ApplicationWide input range 85-264 VAC / 90-375 VDC reduces inventory and simplifies site power planning, enabling smoother machine integration and fewer supply-chain headaches. In practice this means fewer spare power modules and faster changes on production lines where voltage swings occur, especially in multi-site deployments.Output 24 V DC at 1.25 A with 30 W rated power supports standard control logic and I/O networks, delivering consistent performance for PLCs, relays, and sensors while lowering the risk of undervoltage faults in automation panels. This translates to higher line efficiency and more predictable cycle times in packaging, materials handling, and process control.Output voltage is adjustable from 24 to 28 V DC, allowing optimization for different actuators and peripheral devices without swapping hardware, reducing maintenance time and engineering effort for retrofits.Parallel operation for redundancy enables a second unit to take over during a fault, improving system availability in critical applications like CNCs, robotic cells, and conveyors where downtime is costly. This capability supports lean manufacturing and safer changeover processes.Signaling output (transistor) for output voltage OK provides real-time health monitoring to SCADA and HMI systems, enabling proactive maintenance and faster fault diagnosis, which translates into reduced MTTR and improved uptime.DIN rail mounting options (TH35-15 / TH35-7.5) and compact footprint simplify cabinet design and retrofit projects, saving panel space and easing installation in crowded control enclosures.Integrated safety and compliance features (IP20 housing, UL/CSA, CE, UKCA) reduce the need for extensive external protection and facilitate audit-ready documentation for industrial standards, improving procurement confidence and speeding qualification processes.Operating tolerance up to 50 Hz and broad ambient temperature range (-40 to +70 C) support use in harsh environments across manufacturing floors, ensuring reliable operation in heat and dust without frequent replacements. This reliability translates to fewer service visits and lower operating costs over the product life.

FAQs
The CP-E 24/1.25 is designed for DIN rail mounting on TH35-15 or TH35-7.5 rails. Use a PH1 screwdriver, tighten input and output terminals to 0.6 N·m, and ensure a minimum 25 mm mounting clearance on the board. It accepts flexible (0.2–2.5 mm2) or rigid wire for both input and output circuits, simplifying field wiring and serviceability.
The unit supports a wide input spectrum: 100–240 VAC nominal and 85–264 VAC, plus 90–375 VDC. This tolerance minimizes voltage-related voltage drop and performance fluctuations, enabling stable 24 V DC output under varying plant power conditions and reducing the need for additional voltage regulation in multi-site installations.
Yes, the CP-E 24/1.25 includes a signaling (transistor) output indicating voltage OK. It also supports parallel operation with a redundancy unit, allowing a spare supply to take over in the event of a fault, which significantly improves system availability in critical automation tasks.
The device carries CE and UKCA declarations, UL/CSA and cUL certificates, and REACH/RoHS/WEEE conformity. These certifications support regulatory compliance for global installations, simplify supplier qualification, and reduce risk during audits across manufacturing sites.
Typical use cases include control cabinets, PLC power for conveyors, robotics, and machine controls requiring stable 24 V DC. ROI improves through increased uptime due to redundancy, fewer spare parts, and decreased maintenance time thanks to predictive signaling and robust IEC/UL compliance, making it a cost-effective choice for automation builds.
