C9900-U320
The Beckhoff C9900-U320 from the C9 PC Accessories series is a robust DIN rail-mountable UPS providing backup power to IPCs with a NiCad battery capacity of 2.5 Ah and an output voltage of 24 VDC. It supports a charging current of 200-800 mA for flexible charging and achieves a full charge in up to 4 hours. Designed for industrial automation, it operates across an ambient temperature range of 0 to 55 °C and tolerates up to 95% non-condensing humidity. Reverse battery protection is ensured by a fuse on the C2000BAT board, safeguarding against incorrect connections. Integration is seamless via ST501 and ST703 ribbon cables controlled by C1230S or CP9030 boards, and Beckhoff recommends cable lengths of 4 m (1.5 mm²) or 8 m (2.5 mm²) for optimal performance.
