Schneider VAMP55 VAMP 50 series voltage protection modules

The Schneider VAMP 50 series is a module series launched by Schneider for low-voltage and medium-voltage feeder and motor protection, with VAMP55 being one of the models. The modules in this series have multiple functions including voltage protection, and the specific introduction is as follows:

• Multiple Protection Functions: It can provide various protection functions such as overcurrent, ground fault, voltage, frequency, and line differential protection, meeting the protection and control needs of multiple power systems. It is suitable for application scenarios ranging from simple overcurrent protection to bus voltage or line differential protection.

• Rich Measurement Functions: Equipped with complete measurement functions, it can measure parameters such as line and residual current, current imbalance, system frequency, and harmonics, replacing the traditional metering functions in switchgear and control device assemblies.

• Arc Flash Protection: It has a unique ultra-fast arc flash protection function, providing additional guarantees for the overall safety of the device and the reliability of the protection and control system.

• 
  

• Flexible Programming: It has 12 programmable LEDs, including 2 fixed ones (power, error) and 8 freely programmable ones, as well as 2 freely programmable buttons with LEDs, facilitating users to set according to actual needs.

• Intuitive Display: With a single-line diagram simulation function for control, indication, and real-time measurement, it is also equipped with a large-screen LCD display that shows rich information for easy operation and monitoring.

• Flexible Hardware: The hardware design is flexible, allowing easy addition of optional modules such as arc sensor interfaces, DI/DO channel expansion modules, and various communication module adapters. It supports automatic hardware adaptation without the need to modify the firmware.

• Communication Support: It supports the IEC 61850 communication protocol, enabling convenient communication with other devices and systems compliant with this standard to achieve intelligent management and monitoring of the power system.

• Language Support: It supports Unicode languages and can be translated into any language, making it convenient for users in different regions.

• 
  

• Power System: In substations, it can be used to monitor bus voltage, line voltage, etc. When overvoltage, undervoltage, voltage unbalance, or other situations occur, it promptly sends alarm signals or takes protection measures to prevent electrical equipment from being damaged due to voltage anomalies and ensure the stable operation of the power system. It can also be applied to distribution networks to protect the voltage of branch lines, ensuring that the user end obtains stable power supply voltage and reducing the impact of voltage fluctuations on user equipment.

• Industrial Automation Production Lines: In automation production lines of industries such as pharmaceuticals and electronics, many precision devices have extremely high requirements for voltage stability. VAMP55 and VAMP 50 series modules can real-time monitor the power supply voltage, quickly cut off the power or take other protection measures when voltage anomalies occur, avoiding situations such as product quality degradation and equipment failure shutdown caused by voltage problems, and ensuring the continuous and stable operation of the production lines.

• Data Centers: Data centers have a large number of devices such as servers, which have extremely high requirements for the stability and reliability of power supply. Voltage protection modules can be used in the power distribution system of data centers to monitor the voltage of each power distribution cabinet, server rack, etc., preventing voltage fluctuations, surges, etc., from damaging the equipment and ensuring the continuity of data center services.

• 
  

• Rail Transit: It can be applied to the power supply system of rail transit, such as traction substations and station power distribution rooms. The operation of rail transit vehicles has strict requirements for the stability of power supply voltage. These modules can effectively protect the power supply equipment and vehicle electrical systems, cope with voltage changes generated during the starting and braking of trains, as well as voltage anomalies caused by external environmental factors, and ensure the safe and reliable operation of trains.

• Photovoltaic Energy Storage Systems: In centralized or distributed photovoltaic energy storage projects, it is used to monitor the output voltage of photovoltaic arrays, the voltage of energy storage systems, etc. When voltage anomalies occur, it promptly provides protection to avoid damage to photovoltaic modules, energy storage batteries, and other equipment due to overvoltage or undervoltage, and improves the stability and service life of photovoltaic energy storage systems.

• Intelligent Buildings: It can monitor and protect the power supply voltage of equipment such as lighting, air conditioning, and elevators in buildings. For example, when the grid voltage fluctuates, it prevents problems such as lighting fixture flickering and air conditioning compressor damage. At the same time, it also helps improve the overall reliability of the building's electrical system and energy utilization efficiency, providing a comfortable and safe environment for building occupants.
