Lenze EMB9342-E

The Lenze EMB9342-E is a robust and efficient regenerative power supply unit designed to enhance drive systems’ performance and energy efficiency. It is specifically designed to cater to applications requiring reliable and efficient energy management.

Technical Specifications:

The Lenze EMB9342-E operates with a three-phase input voltage ranging from 320V to 528 AC. It has a rated output current of 32A and can handle a peak output current of 64A. It also supports a DC voltage of 65V to 680V, making it suitable for a wide range of industrial applications. It operates at a mains frequency of 48 to 62Hz. The apparent power of the power supply is 16.6 kVA. The power loss is only 200W, making it a highly efficient power supply.

The EMB9342-E is designed to regenerate power, which means it can recover energy that would otherwise be lost during braking or deceleration. This feature helps reduce energy consumption and lower operating costs. In addition, the motor only weighs 7.5kg and has dimensions of 210mm (width) x 450mm (height) x 300mm (depth), making it ideal for use in a space-constrained environment. It is designed for easy installation in control cabinets, with a user-friendly interface for quick setup and configuration

Versatile Application:

This power supply unit is versatile and can be used across various industries, including manufacturing, material handling, and automation. Its ability to handle a wide range of input voltages and output currents makes it suitable for different drive systems and applications.

The Lenze EMB9342-E is suitable for motor control applications, such as conveyor systems, pumps, and fans. The EMB9342-E can be used for power conversion applications, such as DC-DC conversion, AC-DC conversion, and DC-AC conversion. This power supply is designed for industrial automation applications, including robotics, machine tools, and other industrial equipment.

Protection Features:

The regenerative power supply comes with various protection and safety features that make it a reliable power source for many industrial applications. A temperature-controlled fan maintains the optimum temperature of the motor, hence avoiding overheating. The operational state and warnings can be displayed via LEDs. The key parameters are continuously monitored to avoid any malfunction. The power supply has IP20-grade protection.

The heat sinks of the regenerative power supplies can be mounted externally to reduce the heat generated within the control cabinet, thereby improving overall system efficiency and reliability. About 65% of power loss is via the separated heat sink, and 35% is inside the regenerative power supply. The overload protection prevents damage to the supply and connected equipment.

Frequently Asked Questions:

What protection mechanisms are included in the EMB9342-E?

The EMB9342-E is equipped with several built-in protection mechanisms to ensure safe and reliable operation. These include protection against overvoltage, undervoltage, overcurrent, and short circuits. These features safeguard both the power supply unit and the connected drive systems.

What is the operating and storage temperature range of Lenze EMB9342-E?

The allowed temperature, during storage: -25 °C … +55 °C and during operation is 0 °C … +40 °C without power derating. Operating at this temperature is a must for optimal performance.

How does the EMB9342-E enhance the lifespan of drive system components?

By regenerating excess kinetic energy and reducing the thermal load on the drive system, the EMB9342-E helps to improve the overall performance and longevity of the drive components. This energy-efficient approach not only reduces operational costs but also extends the system’s lifespan by minimizing wear and tear on the components.
