ABB 1SVR427043R1200 Power Supply 12 VDC 2.1 A

ABB CP-D 12/2.1 DIN-rail switching power supply, part number 1SVR427043R1200, provides a regulated 12 V DC output at up to 2.1 A from a compact module designed for DIN-rail installations in control cabinets. It accepts a broad mains range — 90–264 V AC or 120–375 V DC — with nominal 100–240 V AC input; a small potentiometer allows output adjustment from 12 to 14 V DC to accommodate voltage variations in real-world installations. The unit includes an internal 2 A slow-blow fuse (not user-accessible) for apparatus protection and has status indicators (green LED when powered, red LED when output is too low). The CP-D 12/2.1 family is intended for automation environments powering 12 V loads such as PLCs, sensors, and actuators, delivering a compact, modular solution that integrates into DIN-rail control panels. The order code 1SVR427043R1200 confirms the CP-D 12/2.1 specification and aligns with ABB’s documentation for a 12 V DC/2.1 A output in a 90–264 V AC (or 120–375 V DC) input power module.
