LEGRAND UPS Keor SPE Rack 1U 750VA
The LEGRAND UPS Keor SPE Rack 1U 750VA backup power supply is a compact power protection solution with line-interactive topology, an apparent power of 750VA and a real power of 525W. This low-profile 1U model delivers a pure sine wave and offers a runtime of 4 minutes at full load. Thanks to its design, it's ideal for mounting in standard 19″ server racks, where it effectively protects sensitive network infrastructure from outages and power grid instability. Inside the metal chassis are four sealed VRLA lead-acid batteries, which supply power during a complete primary power failure. The system includes deep discharge protection, which extends the overall life of the batteries. The cold start function allows connected devices to be powered up even without mains voltage. An integrated potential-free switching contact and an automatic shutdown function in the event of a critical overload further enhance operational safety.
Key features of the LEGRAND UPS Keor SPE Rack 1U 750VA backup power supply
- Line-interactive topology with a pure sine wave output for sensitive electronics
- Automatic Voltage Regulation (AVR) protects connected equipment without draining the battery
- Compact 1U design for mounting in 19" rack cabinets
- Remote management and monitoring via SNMP communication interface
- Cold start function to power up connected devices without mains power
- Five fully backed-up IEC C13 output sockets
- Potential-free contact for status signalling and automatic safe shutdown
Topology and stable performance
This backup power supply operates on line-interactive technology, which responds to fluctuations in the electrical grid. The device provides an apparent power of 750VA and a real power of 525W with an output power factor of 0.8. The integrated AVR system automatically regulates the voltage in the range of 175V to 288V, thus preventing unnecessary battery discharge. When operating in ECO mode, the overall system efficiency reaches a high of 98%, reducing operating costs and the amount of heat radiated.
Network management and monitoring
Connection to control systems is via the built-in USB communication interface. The backup power supply supports network management using an SNMP card, which enables remote monitoring and real-time parameter configuration. The accompanying software performs an automatic safe shutdown of connected servers and storage devices in the event of a prolonged power outage. Users can monitor the current load status and battery capacity directly via the network interface.
Connectivity and sockets
The input power is connected using a standard IEC C14 connector. Five IEC C13 type output sockets are used to distribute power to the protected devices. One IEC Jumper connection cable is also included. All available sockets are fully backed up by the internal battery and protected against voltage spikes.
