SERVER TECHNOLOGY, 4870-XLS-44, SENTRY 48VOLT DC REMOTE POWER MANAGER

The Server Technology 4870-XLS-44 is a 48V DC remote power manager designed for critical infrastructure requiring distributed power control and real-time load monitoring. This Sentry XLS series unit enables remote on/off switching, individual outlet metering, and environmental monitoring across four independently controlled terminal pairs. It reduces downtime and on-site service calls through browser-based and serial management interfaces, supporting HTTP(S), SSH, SNMP, and multiple connectivity protocols for integrated cabinet-level power oversight.
