Description
Electronic Measurements TCR 120T40-1-D-0V 4800W DC Power Supply 0-120VDC 40A 3Ph
The Electronic Measurements Inc. TCR 120T40-1-D-0V is a heavy-duty variable DC power supply rated at 4800 watts, delivering a continuously adjustable output from 0 to 120 VDC at up to 40 amps. It draws power from a three-phase 208/220 VAC line, making it suited for industrial and laboratory environments with three-phase service. Electronic Measurements Inc. (EMI), later absorbed into Lambda and then TDK-Lambda, produced the TCR series as a line of workhorse programmable and manually-controlled DC power supplies widely used in industrial testing, electrochemical processes, and laboratory applications.

Applications
The TCR series from Electronic Measurements Inc. is a line of high-power DC power supplies designed for demanding industrial, laboratory, and process applications requiring wide-range variable voltage and current control. Units of this class are commonly used in electroplating, anodizing, and electrochemical processing where precise, stable high-current DC output over a broad voltage range is needed. They are also widely used in burn-in and life-testing systems, where electronic assemblies are stressed at elevated voltages and currents for extended periods. Research laboratories and university facilities use variable supplies in this power class for materials testing, motor drive development, and power electronics research. The TCR product line was introduced by Electronic Measurements Inc. and remained in production after the company's acquisition by Lambda Electronics and subsequently TDK-Lambda; as a result, this model is searched under all three brand names. The TCR 120T40 in particular — 120 volt / 40 amp output — occupies a useful mid-range position for applications that need substantial current at moderate voltages, such as battery formation and testing or high-power resistive load evaluation. This unit requires three-phase power and is large enough to require freight shipping.
This Electronic Measurements TCR 120T40-1-D-0V 4800W DC Power Supply has been inspected and appears to be in good overall condition. It was pulled from a working environment where it was in use and functional. The blue front panel shows general surface wear consistent with age and industrial use, including scuffing and minor scratches. The gold/silver chassis shows some discoloration and surface oxidation on the sheet metal. The output leads are included but show notable wear: the banana plug connectors show corrosion and heavy use, and the cable insulation is split along a section of the cable, exposing bare copper conductors — buyers should plan to replace or repair the output leads before use. The front-panel digital meters, voltage and current control knobs, three-pole power switch, phase loss indicator, and O.V. adjust trimmer are all present. This is a large, heavy unit (approximately 205 lbs) and will require freight shipping. Please contact us for a freight quote, to arrange local pickup, or to schedule a viewing at our facility.
