The CP-T 24/20.0 delivers a stable 24 VDC output up to 20 A, ensuring PLCs and motor controllers receive reliable power with minimal ripple. This means fewer nuisance faults and smoother automation cycles, especially in high-load cabinet environments where sudden voltage dips can crash processes. Designed for 3x400-500 VAC input at 50 Hz, it simplifies global installation by accommodating common European and international electrical standards. Operators benefit from reduced wiring complexity and lower total cost of ownership when replacing legacy supplies or integrating new machines in mixed-voltage facilities. The unit offers selectable U/I characteristic curves or hiccup-mode operation, enabling controlled response to overloads. This provides predictable shutdown behavior that protects connected equipment and minimizes downtime during fault conditions, while allowing quick recovery after transient events. The CP-T 24/20.0 delivers up to 480 W of continuous power and is compatible with a wide range of sensors and actuators, facilitating turnkey control panel design. With IP20 housing and robust EMC immunity, it is suited for common control cabinets in factory floors, and compliance with UL 508, CE, and UKCA reduces regulatory risk. Its DIN rail mounting and compact footprint simplify installation in dense panels, while the 131 mm height and 150 mm width optimize space planning. Operating in a wide temperature range of -30 to +70 °C and up to 5000 m altitude, the supply maintains performance in harsh environments. The unit’s RoHS, REACH, and WEEE declarations support sustainable asset management and end-of-life planning.

Key specs include a 480 W rated output power, 24 VDC output at up to 20 A, input voltage of 3x 400–500 VAC (also listed for 340–575 VAC inputs), 50 Hz nominal frequency with 47–63 Hz tolerance, and an IP20 enclosure. It supports U/I curves or hiccup-mode for overload protection, delivering reliable performance in automation cabinets.
The CP-T 24/20.0 carries UL 508 and UL/CSA recognition, along with CE and UKCA declarations of conformity. These certifications cover safety and electromagnetic compatibility, facilitating regulatory compliance in North American and European markets. RoHS and REACH declarations further support environmental compliance, while WEEE classification helps with end-of-life responsibilities.
Yes. The unit operates from -30 to +70 °C and supports use at altitudes up to 5000 m, providing resilience in challenging industrial settings. IP20 protection guards against incidental finger contact, and EMC immunity levels meet Class B/industrial environment expectations. This makes it a robust choice for machine controls, automation panels, and process instrumentation in demanding facilities.
The CP-T 24/20.0 is designed for long service life with a 480 W continuous output, minimizing downtime from voltage fluctuations. Its compact DIN-rail form factor reduces panel space costs, while UL/CE/UKCA compliance lowers regulatory risk. With standard wiring practices and straightforward field wiring, maintenance is simplified, contributing to lower total cost of ownership in control cabinets over the asset lifecycle.
