Who Should Buy?

Suitable For
  • Electrical Engineers

    Ideal for engineers needing precise voltage monitoring in three-phase systems, ensuring equipment protection against voltage irregularities.

  • Industrial Facilities

    Beneficial for manufacturing plants to prevent downtime caused by phase failures or over/under voltage scenarios.

  • Maintenance Personnel

    Serves maintenance teams by providing real-time monitoring and alerts, enhancing proactive maintenance strategies in electrical systems.

Not Suitable For
  • Residential Users

    Not suitable for homeowners as domestic voltage variations often do not necessitate such specialized monitoring equipment.

  • Small Businesses

    May be excessive for small operations that do not operate on three-phase power or lack critical voltage-sensitive equipment.

  • Casual Hobbyists

    Not recommended for hobbyists who work with low-power devices, as they may not require advanced voltage monitoring solutions.

Customer Questions & Answers

  • Question: What is a 3 Phase Voltage Monitoring Sequence Relay?

    Answer: A 3 Phase Voltage Monitoring Sequence Relay is a protective device designed to monitor the voltage levels in a three-phase electrical system. It ensures that the voltage remains within safe operating limits and can intervene if it detects conditions such as over-voltage, under-voltage, or phase failure. This relay is crucial for applications in industrial settings where maintaining consistent power supply is vital for the functioning of machinery and equipment.
  • Question: How does the JVR800-2 Under Over Voltage Protector work?

    Answer: The JVR800-2 Under Over Voltage Protector operates by continuously monitoring the voltage of your electrical system. When it detects that voltage rises above or falls below pre-set thresholds, the device activates its protective mechanisms, which could include shutting down the equipment or sounding an alert. This ensures that your machinery is safeguarded against voltage fluctuations that could lead to operational inefficiencies or damage.
  • Question: What are the key features of the JVR800-2 Voltage Relay?

    Answer: The JVR800-2 Voltage Relay features LCD display for real-time monitoring, programmable voltage settings, and delay timers to prevent nuisance tripping. Its design includes various input thresholds for both under and over-voltage conditions, making it versatile for different applications. This relay's programmable nature allows for customization based on specific operational needs, providing flexibility for users managing varying voltage environments.
  • Question: What applications can benefit from using a Voltage Over Under Voltage Phase Failure Relay?

    Answer: A Voltage Over Under Voltage Phase Failure Relay is beneficial in applications such as water treatment plants, manufacturing facilities, and HVAC systems where consistent voltage is crucial for performance. These relays ensure that equipment runs smoothly even in fluctuating voltage conditions, thereby reducing the risk of malfunctions that could lead to costly repairs or operational downtime.
  • Question: What is the role of an LCD display in the Voltage Monitoring Relay?

    Answer: The LCD display in the Voltage Monitoring Relay provides a clear and visual representation of voltage levels at any given time. Users can easily monitor real-time data, making it simpler to identify fluctuations that may require attention. This feature enhances user experience as it allows for quick assessments of system status, ensuring operators can take immediate action when necessary.
  • Question: Can the JVR800-2 be used for single-phase applications?

    Answer: While the JVR800-2 is primarily designed for three-phase systems, it can also provide monitoring capabilities for single-phase applications, but with limitations. Users may find it beneficial for monitoring larger single-phase equipment to ensure safe operation within voltage thresholds. However, sticking to the specifications of the relay is important for optimal performance.
  • Question: What should I do if the relay keeps triggering alarms?

    Answer: If the relay keeps triggering alarms, check the voltage supply to ensure it is within the set thresholds. Possible causes of repeated alarms could include actual voltage fluctuations, improper settings, or faulty wiring. Reviewing the relay's settings and comparing them to the actual system conditions can help diagnose the issue. Consulting the user manual or a qualified technician can provide additional assistance.
  • Question: Is the JVR800-2 suitable for outdoor installations?

    Answer: The JVR800-2 is primarily designed for indoor use, where consistent environmental conditions can be maintained. For outdoor use, it may require additional protective housing to shield it from elements like moisture, dust, and extreme temperatures. Users should assess their installation conditions to ensure the device is adequately protected, which is critical for maintaining performance and longevity.
  • Question: How can I install the Voltage Monitoring Relay safely?

    Answer: To install the Voltage Monitoring Relay safely, follow the manufacturer's guidelines regarding electrical connections and positioning. Ensure that the power is turned off during installation to prevent electrical hazards. Using the appropriate gauge wire and connections also helps avoid overheating and potential failures. Proper installation ensures that the relay operates effectively, providing necessary protections.
  • Question: Where can I buy the 3 Phase Voltage Monitoring Sequence Relay, JVR800-2 in Sri Lanka?

    Answer: You can purchase the 3 Phase Voltage Monitoring Sequence Relay, JVR800-2 from Ubuy in Sri Lanka. Ubuy offers a variety of electronic components and equipment, ensuring that you can find the relay you need for your electrical monitoring requirements.
