The ACC-E1 is an AC power supply module for OMRON/Delta Tau UMAC motion control systems. This accessory card mounts directly to the UBUS backplane and supplies regulated DC outputs—+5Vdc, +15Vdc, and -15Vdc—essential for UMAC system stability and performance. The module eliminates external power wiring by integrating directly into the backplane, simplifying installation and reducing integration complexity.
