The APC Symmetra LX SYA4K8RMI is a rack-mount uninterruptible power supply rated at 4 kVA (2800 W) and scalable to 8kVA N+1. It delivers sine wave output at a nominal 230 V from a single-phase 230 V hard-wired input, with a maximum input current of 18 A.
Output connections comprise one hard-wire 3-wire connection, 8 IEC 320 C13 and 6 IEC 320 C19 outlets. Typical backup time is 20 min at half load and 7.5 min at full load, with a 3 h battery recharge time. The lead-acid batteries are replaceable by the end user. Management is provided through DB-9 RS-232 and Smart-Slot interfaces, and the unit includes Emergency Power Off (EPO) and an audible alarm. It measures 472 x 688 x 572 mm and weighs 134.1 kg.
The SYA4K8RMI suits server rooms and data centre racks that need conditioned backup power with room to add capacity. It operates from 0 to 40 °C and up to 3000 m altitude.
