The TDK-Lambda DPP240-48-1 is a 240 W AC-DC switching power supply housed in a compact DIN rail mountable enclosure for industrial automation and ITE applications. It delivers fixed 48 VDC output at 5 A maximum, with adjustable output voltage from 47 to 56 VDC. The unit accepts single-phase AC input from 90 to 264 VAC (47–63 Hz) or DC input from 210 to 370 VDC, achieving typical efficiency of 90%. Convection cooling enables operation across -40 to 71°C ambient temperature. Over-current protection activates at 110–145% of rated output current.
