Product Overview

• Part No: CP-E 24/1.25
• Order code: 1SVR427031R0000
• Brand: ABB
• Series: CP-E economic industrial power supply series
• Type: DIN rail mounted primary switching mode power supply

• Function: Converts AC mains to stable 24V DC power supply for PLC, sensors, relays, small control modules and field instruments inside automation cabinets. It supports voltage fine tuning to offset cable voltage drop, can be paralleled for redundant power supply, and sends transistor level DC OK signal for upper system monitoring.
