Sentinel Tower UPS with Online double conversion topology provides maximum protection for sensitive equipment, especially in the field of information technology. The use of a three-level inverter in this UPS has led to an increase in device efficiency of up to 95% in Online mode, reducing energy losses and increasing system efficiency. Filters installed at the input and output of the UPS eliminate most of the power outages and fluctuations and prevent possible damage to downstream systems. The ER series of this UPS does not have an internal battery and is equipped with a high quality and power switching charger that can charge external batteries with high charge current. The use of a digital fan speed controller increases the fan speed if the load increases and vice versa, leading to a reduction in circuit losses and the noise produced.

Function selection in ECO, Online and Smart active modes is done using the user-friendly front panel display. With USB ports and RS-232 serial ports, remote emergency terminal (EPO), slots for communication equipment such as the NetMan 204 module and slots for parallel cards, any possible connection to this UPS is well anticipated. On the back panel are two independent IEC 320 C13 programmable outputs that can be programmed to automatically turn on or off connected consumers in certain situations.
(1) It is possible to install output isolating transformers in 5000 and 6000 capacities as custom equipment.
(2) It is possible to provide a battery box compatible with the body of the device, if ordered.
(3) To perform Parallel operation, a parallel card must be provided for each UPS.
(4) UPS monitoring under TCP/IP protocol requires NetMan 204 module and under Modbus/Jbus protocol requires MultiCOM 302 module.
