Power Master Unit Software [top] - Elster Metering Systems

The Elster Power Master Unit (PMU) is a utility-grade Windows-based software designed for the local and remote management of Elster Metering Systems' programmable single and polyphase electricity meters. It serves as a central tool for engineering and field teams to handle meter configuration, data retrieval, and system diagnostics. Key Features and Capabilities

Remote & Local Reading: Easily retrieve data from meters via various communication channels, including PSTN, GSM modems, RS232, RS485, or optical FLAG probes. Elster Metering Systems Power Master Unit Software

Elster A1120/A1140: Known for versatile communication options and used extensively in electronic business metering. The Elster Power Master Unit (PMU) is a

Software Versions: Common versions found in field use include PMU 2.4 for A1140/A1700 meters and PMU 3.0 for AS230 meters. With PMUs (e

Operational Efficiency

Without a PMU, a utility with 50,000 meters might need to poll each meter individually over a wide-area network (e.g., cellular), incurring data plan costs for 50,000 devices. With PMUs (e.g., 50 PMUs managing 1,000 meters each), the utility only pays for 50 cellular connections. The PMU aggregates data locally, slashing communication costs by up to 95%.
