Tabular network parameter analyzer, TrueRMS SM103E

Multifunctional network parameter analyzer

The Hager SM103E tabular network parameter analyzer, TrueRMS, is an advanced measuring device designed to monitor energy quality in electrical installations. It will be useful both in industrial applications and in commercial or residential buildings, where precise analysis of network parameters is crucial for optimizing energy consumption and ensuring safety. The device offers a wide range of measurements, from voltage and current, through active, reactive and apparent power, to power factors and harmonics.

Features and application

The SM103E analyzer enables a comprehensive analysis of the electrical network, providing data necessary to identify potential problems, such as overloads, voltage asymmetries or the presence of harmonics. This allows for a quick response to irregularities and prevention of failures. The device finds application in:

• Energy consumption monitoring: Allows for accurate measurement of energy drawn and delivered, which facilitates cost optimization.
• Energy quality analysis: Detects disturbances in the network, such as harmonics, which can negatively affect the operation of devices.
• Electrical installation diagnostics: Helps identify problems with wiring or electrical devices.
• Protection against overloads: Monitors network load and warns of exceeding permissible values.
• Control of device operating parameters: Allows monitoring of voltage, current and power consumption by individual devices.

Technical specifications and benefits

The device is characterized by high measurement accuracy (class of active energy accuracy 0.5S) and a wide measurement range of voltage (110-400V AC) and current (up to 9995A). It has 3 current measurement inputs and 4 voltage measurement inputs as well as 7 analog inputs. Communication is via the Modbus protocol, enabling integration with building or industrial automation systems. The IP51 protection class provides resistance to dust and moisture. Mounting is done on a TS rail, which facilitates installation in electrical switchboards. High measurement precision allows for reliable data analysis and making informed decisions regarding energy consumption optimization and improving installation safety. Additionally, the compact dimensions (96 x 96 x 60 mm) allow for easy placement of the analyzer in a limited space.
