VREL-11
- Manufacturing Industry: In manufacturing plants, the VREL – 11 can be used to control the power supply of various production equipment, such as robotic arms, conveyor belts, and machine tools. It ensures stable power supply and protects these devices from voltage surges, which is essential for maintaining the accuracy and efficiency of the production process.
- Power Generation and Distribution: In power plants and power distribution systems, this module can be applied to protect power – related equipment, such as generators, transformers, and switchgear. By preventing voltage spikes from affecting these key components, it helps to ensure the stable operation of the power grid and reliable power supply to end – users.
- Industrial Automation Systems: For general industrial automation systems, the VREL – 11 can be integrated into control cabinets to protect a wide range of electrical components, including sensors, actuators, and communication modules. It plays a vital role in maintaining the integrity and stability of the entire automation system, reducing the need for frequent equipment maintenance and replacement due to electrical failures.
3. Product Parameters
3.1 Electrical Parameters
- Operating Voltage: It usually operates at 220 V (in some cases, the voltage rating is specified as 240 V AC). This voltage level is commonly used in industrial electrical systems, providing a stable power source for the module to function effectively.
- Frequency Range: The frequency range is typically 30 kHz, which allows it to work in harmony with industrial power supplies and electrical components operating within this frequency band.
- Current Rating: Some sources indicate a maximum current rating of 100 A, while others specify a current rating of 10 A. This indicates its ability to handle different levels of electrical loads, depending on the specific application requirements.
- Voltage Protection Level: With a voltage protection level of 1.5 kV, it can effectively limit the voltage that may reach the protected equipment during voltage surge events, ensuring the safety of the connected devices.
- Surge Current Rating: It has a surge current rating of 10 kA, which means it can withstand large – magnitude transient currents during voltage surges without being damaged, thus providing reliable protection.
3.2 Performance Parameters
- Response Time: As mentioned, the response time is less than 1 millisecond (or less than 1 nanosecond in some descriptions), ensuring rapid protection against voltage fluctuations.
- Mechanical Life: The mechanical life of the module is specified as 10 million cycles in one reference. This indicates its durability and long – term reliability in applications that involve frequent on – off operations.
- Electrical Life: The electrical life is 1 million cycles, which sho
ws its ability to maintain proper electrical performance over a large number of operating cycles.
3.3 Environmental Parameters
- Operating Temperature Range: It can operate within a wide temperature range, from – 40 °C to + 85 °C. This wide temperature tolerance makes it suitable for use in diverse industrial environments, from cold storage facilities to hot manufacturing workshops.
- Environmental Rating: With an IP65 (in one source) or IP67 (in another source) environmental rating, it offers high – level protection against dust and water ingress. An IP65 rating means it is protected against dust ingress and low – pressure water jets from any direction, while an IP67 rating indicates it can be immersed in water up to 1 meter deep for a short period without damage, making it suitable for both indoor and outdoor industrial applications.
4. Product Specifications
- Physical Dimensions: The module has compact dimensions, typically 200 mm (length) x 150 mm (width) x 50 mm (height). Its small size allows for easy installation in standard industrial control cabinets, saving valuable space in industrial control rooms.
