The UPS adopts double-conversion topology to provide high-quality power output with additional ECO Mode to conserve power and save on energy costs. The UPS supports parallel expansion to allow the connections of multiple UPS units, achieving system redundancy. It is compatible with generators to prolong power continuity, and maintenance bypass switch to provide quick and safe maintenance without having to shut down UPS and connected equipment. The product can be connected to Emergency Power Off (EPO) switch, allowing users to shut off UPS immediately during emergency.

Design and battery management

The UPS can employ Extended Battery Modules (EBM) to prolong runtimes, and its built-in Smart Battery Management (SBM) enhances battery charging process to extend battery lifetime. This model also features multifunction LCD readout to display information of power and battery conditions. The PowerPanel Power Management Software allows user to perform real-time monitoring and remote management of the UPS.

Installation and expansion

The OLS3S20KE is a tower unit for floor or desk placement. Add BPSE240V82A extended battery modules for longer runtime. Fit the optional RMCARD205 for SNMP/HTTP network monitoring and scheduled shutdowns with PowerPanel.
