The Teknic SSt-EMF75 is a linear, unregulated 75 VDC power supply engineered for industrial automation and motion control systems. Built with a transformer, bridge rectifier, regeneration circuit, and 47,000 μF output capacitor, it delivers stable DC power across multiple drive axes while eliminating the need for individual per-axis supplies. The unit captures regenerative motor energy to reduce overall machine power consumption and operates with exceptional reliability—MTBF measured in decades.
