The Emerson EBU01 is a specialized battery supervisory telemetry module engineered for telecom sites, data centers, and utility substations. It interfaces with Emerson PSM or M500S supervisory controllers via high-speed differential bus, providing precise real-time monitoring of battery string voltage, midpoint symmetry, and cell temperatures.
Eliminates the risks of manual battery maintenance delays, undetected cell premature failure leading to entire string deterioration, and unmonitored string midpoint voltage drift.
Ideal for cellular macro sites, telecom central offices, data center UPS battery rooms, electrical switchgear DC systems, and railway signaling backup battery arrays.
