Schneider Electric 8005 EPU-1 SY MAX 72274 External Power Unit

The Schneider Electric Square D SY/MAX Class 8005 EPU-1 external power unit provides a 24 VDC supply at up to 0.5 A to power SY/MAX PLC I/O modules and sensors from a 120–240 VAC input. The unit presents about 25 VA of input power at 50/60 Hz and supports a nominal 120–240 VAC supply (documentation also notes an 85–264 VAC range), delivering a compact 24 VDC output capable of 0.5 A to local I/O. It is designed to mount with SY/MAX base configurations and can be paired with an I/O module or another external power unit to expand power distribution in a SY/MAX system. Key electrical specs include an input inrush current up to 40 A, overcurrent protection via a fuse, and an output noise of 500 mV peak-to-peak; dielectric strength between I/O terminals and ground of 1500 VAC for 1 minute; and insulation resistance of at least 10 MΩ at 500 V. The external unit weighs approximately 230 g, reflecting its compact enclosure for panel or control cabinet installations. This 8005-EPU-1 is part of Square D SY/MAX Class 8005, and in some listings is identified by the 72274 suffix as the external power unit model.
