Schneider BIK 121 Automation Power Supply

Technical Overview of This Industrial Power Source

The Schneider BIK 121 delivers stable DC power to automation equipment. This power supply belongs to Schneider Electric’s legacy industrial component family. It converts AC mains voltage into regulated 24 V DC output. Consequently, your PLC and I/O modules receive clean operating power.

Hardware Specifications and Design Details

This power supply weighs approximately 0.8 kg. Its compact dimensions are 120 mm in height, 70 mm in width, and 100 mm in depth. The Schneider BIK 121 features a single-phase AC input interface. It uses a screw terminal block for line and neutral connections. The device contains one internal transformer and one rectifier circuit board. It stores minimal energy in its output capacitors for short-term hold-up. Therefore, the module maintains output for approximately 20 milliseconds during input dips.
