The Lambda / TDK EMI TCR150S4-1 is a programmable DC power supply engineered for industrial and laboratory environments requiring stable, filtered power delivery. Built-in RFI/EMI filtering with ferrite toroidal chokes and VDE-listed capacitors ensures minimal electromagnetic interference. The unit operates from 3-phase AC input with automatic phase-loss detection and soft-start SCR phasing to eliminate magnetic inrush current.
