The Lambda/TDK/EMI LNS-W-5-OV is a linear, convection-cooled power supply delivering 63 W at 5 V DC for industrial and commercial applications requiring low-noise, stable power. This single-output unit is engineered for systems with sensitive analog circuits, offering 1.5 mV RMS ripple and 5 mV peak-to-peak noise. Overvoltage protection and automatic electronic current limiting are standard, with remote sensing capability to compensate for lead resistance effects on DC regulation.
