ADVANTGAES:

 

Exceptional Efficiency with Rectifier Hibernation (Up to 96%). LmPower’s 3000W rectifiers operate at an impressive 96% efficiency, reducing energy waste and operational costs. The rectifier hibernation/cycling function further optimizes energy use during low load periods, which is crucial for telecom networks and data centers aiming to minimize power consumption and heat output.

 

Hot-Swappable Rectifiers with N+1 Redundancy. Hot-swappable design allows maintenance or replacement of rectifiers without system downtime. N+1 redundancy ensures continuous operation even if one rectifier fails, making it ideal for critical infrastructure where uptime is non-negotiable.

 

Intelligent Battery Management and LLVD/BLVD Protection. The intelligent battery management system monitors battery health, temperature, and charging conditions to extend battery life. Built-in Low Voltage Load Disconnect (LLVD) and Battery Low Voltage Disconnect (BLVD) features protect both the load and batteries from deep discharge, reducing risk of failure.

 

Advanced Remote Monitoring & Control. With TCP/IP, SNMP, serial, and web browser interfaces, operators can remotely monitor, configure, and troubleshoot the system. This capability improves responsiveness, reduces service costs, and supports network-wide power management from a central location.

 

Wide Operating Temperature Range (-40°C to +65°C). The LmPower Series is built to withstand harsh environmental conditions, from freezing cold to high-heat installations. This makes it highly reliable for outdoor telecom enclosures, remote base stations, and industrial sites without climate control.
