Industrial CU8110-0120 Capacitor Module for UPS

Beckhoff CU8110-0120 is a capacitive UPS module that uses maintenance-free EDLC energy storage to deliver a compact 0.9 Wh backup with a maximum output of 110 W, keeping critical 24 VDC loads powered when the primary input drops. It provides two 24 V DC outputs via two 9-pin push-in connectors, suitable for a main device (e.g., Industrial PC) and a secondary device (such as a control panel), and is designed for DIN rail TS35x15 mounting (2.3) or rear-panel installation. Communication options include USB 2.0 and UPS-OCT, enabling protocol-based control and diagnostics from Beckhoff software, with three diagnostic LEDs indicating input voltage, output voltage, and status. The unit operates from a 24 V DC supply (tolerance -15%/+20%), and can deliver up to 4.5 A on the output while incorporating internal electronic fuses (10 A input, 5 A output) for protection. Dimensions are 100 x 100 x 90 mm and weight around 780 g, with a -25 to +50 °C operating temperature range. Designed specifically for the CU81xx family, it supports features such as automatic switch-off based on residual energy, autonomous restart when power is restored, and digital signaling for non-protocol-capable devices, making it a robust choice for industrial PCs, embedded PCs, panels, and panel PCs that require reliable 24 V backup and seamless integration with Beckhoff’s configuration software.
