SPSM

The SPSM (Smart Power Switching Module) is a next-generation automatic power management and changeover system engineered to ensure uninterrupted operation of telecom networks and critical infrastructure sites. It intelligently controls the transition between utility mains and diesel generator (DG) power, maintaining continuous load supply during grid outages.

Purpose-built for remote and unmanned installations, the SPSM consolidates monitoring, protection, and control within a compact, integrated panel. It continuously tracks mains availability, DG performance, battery status, and key environmental parameters, automatically executing load transfer and generator operations based on predefined intelligent logic.

Powered by a microcontroller-based architecture, the system delivers precise automation, real-time performance visibility, detailed event logging, and seamless communication with external monitoring platforms. Compatible with 3-phase, 2-phase, and single-phase power configurations, the SPSM offers flexible deployment across diverse telecom and industrial power environments.
