Lambda / TDK / EMI EMS60

The TDK-Lambda EMS60 series is an enclosed AC-DC power supply engineered for industrial and medical applications requiring high reliability and compact power delivery. These units deliver up to 600W across a range of output configurations, supported by universal AC input, active power factor correction, and integrated protection circuits. Built-in soft start limits inrush current, while CV/CC operation with automatic crossover handles both constant voltage and constant current loads. Programmable via analog control or optional RSTL digital interface, the EMS60 maintains tight line and load regulation of 0.1% each, with typical carrier ripple of 75 mV P-P (40 mV P-P available on select models). Internal cooling fans enable continuous operation from 0°C to 70°C ambient, with 1% per degree Celsius derating above 50°C.
