Features

One of the standout features of the EMB9343-E is its ability to connect multiple controllers via a DC-bus system. This arrangement not only simplifies the overall wiring of the system but also enables the central mains supply to be efficiently managed through the regenerative power supply module. By intelligently redistributing the generated power, the module contributes to increased energy efficiency and reduced power consumption.

Operation

The EMB9343-E module incorporates advanced technology to ensure seamless operation and optimal performance. It is equipped with automatic rotating field detection, enabling quick and accurate synchronization with the existing system. The module can also be easily synchronized with internal or external voltage sources, providing flexibility in system integration.

To maintain optimal operating conditions, the EMB9343-E features a temperature-controlled fan that ensures efficient cooling. This helps prevent overheating and guarantees reliable performance even in demanding industrial environments. The module also includes an LED display that provides clear and intuitive information about the operating state, allowing for quick diagnostics and troubleshooting.

Design

Lenze has designed the EMB9343-E module with a focus on adaptability to different mains voltages. The module automatically adjusts the regenerative voltage threshold based on the mains voltage, ensuring compatibility and stability in diverse power supply environments. Additionally, the module incorporates comprehensive monitoring capabilities for mains voltage, mains frequency, DC-bus voltage, and temperature. These monitoring features provide real-time insights into the system's electrical parameters, enabling proactive maintenance and enhancing system reliability.

Approvals

In terms of compliance and approvals, the EMB9343-E module adheres to the CE directives, including the Low Voltage Directive (2006/95/EC) and the EMC Directive (2004/108/EC). It also meets the requirements of the EAC (Eurasian Conformity) regulations, specifically the Technical Regulation of the Customs Union (TR CU 004/2011) for the safety of low voltage equipment and TR CU 020/2011 for electromagnetic compatibility of technical means. Additionally, the module has received UL (Underwriters Laboratories) and CSA (Canadian Standards Association) approvals, ensuring its suitability for use in the USA and Canada.

Compliance

Electrically, the EMB9343-E module meets stringent electromagnetic compatibility (EMC) requirements specified in IEC 61800-3. When installed according to the demands of the CE-typical drive system, it complies with noise emission limits (limit class C2 to IEC 61800-3) and demonstrates excellent noise immunity. The module also possesses insulation resistance capabilities and discharges current specifications necessary for safe and reliable operation.

The EMB9343-E module is designed to operate in challenging environmental conditions. It conforms to Class 3K3 according to EN 60721-3-3, allowing it to function reliably without condensation within a wide temperature range of 5°C to 40°C. The module can withstand transportation and storage temperatures ranging from -25°C to +70°C and is rated for operation at altitudes up to 4000 meters above mean sea level.

Installation

For installation, the EMB9343-E module is intended to be mounted vertically, with the power connection located at the top. Adequate mounting clearances of 100 mm above and below the module are necessary to ensure proper ventilation and ease of maintenance. The module is encased in an IP20 enclosure, providing protection against accidental contact and complying with NEMA 250 type 1 standards.

The permissible mains types for the EMB9343-E module include mains with grounded neutral (TT/TN), while mains with isolated neutral (IT mains) or grounded phase conductors are not permitted. This ensures compatibility with a wide range of power distribution systems commonly found in industrial settings.
