The APC Smart-UPS SMT750RMI2UNC is a line-interactive UPS with an output capacity of 0.75 kVA and an output power of 500 W. The device is designed for use in server and network environments where reliable power supply and protection against voltage fluctuations are required. The UPS provides a sine wave output, suitable for sensitive IT equipment such as servers, POS systems, network switches, or medical devices. The input voltage range extends from 151 V to 302 V, enabling the device to operate stably even during voltage fluctuations in the grid. The output voltage is between 220 V and 240 V, regulated with an accuracy of ±5 % to ensure a constant supply. The response time is 2 ms, enabling rapid transition to backup power in case of a power failure.
Applications
The UPS is specifically designed for use in IT infrastructures, particularly in server rooms, small offices, or critical applications where a power failure could lead to data loss or operational interruptions. The integrated web-based management via the network card (AP9641) enables remote monitoring and control over the network. This is especially useful in distributed IT infrastructures, where the UPS can be monitored and controlled via the SNMP protocol. The PowerChute Network Shutdown software can trigger a controlled shutdown of servers and virtual machines in case of battery discharge, preventing physical damage and data loss.
Functions and Equipment in Detail
The device features 4 AC outputs with C13 connectors, suitable for powering IT equipment. The input is equipped with a C14 connector. An integrated LCD display allows viewing of operating status, battery charge level, and alarm messages. Additionally, LED indicators visually signal the operating status. The UPS supports automatic battery testing and cold start, enabling activation even when the mains power is off. The hot-swap battery allows battery replacement without interrupting the power supply, which is advantageous for critical applications.
Technology Explained Simply
The line-interactive topology ensures that the UPS regulates the mains voltage without using the battery actively, as long as the mains supply is stable. In case of voltage fluctuations or power failure, it switches to battery power within 2 ms. The battery technology is based on sealed lead-acid (VRLA), offering high durability and safety. The battery capacity is 168 Ah, and the charging time is 3 hours. The pressure rise protection function protects the device against overpressure in the battery system. The acoustic alarms notify of critical conditions such as battery replacement requirement.
Compatibility and Accessories
The UPS is equipped with a network card (AP9641) enabling remote management via Ethernet (RJ-45) and USB. Additionally, a SmartSlot is available, allowing installation of further management cards. As accessories, compatible batteries such as the RBC123 are available for replacing the internal battery. Other compatible devices include the UPS PR750ERT2UC and management cards such as the AP9640 or AP9641, which offer extended monitoring functions.
