Product details
The world is rapidly adopting and implementing smart meter solutions, which offer significant benefits for both users and utility companies. Smart meters enable users to manage their energy consumption according to their needs, fostering greater efficiency and cost control. On the other hand, utility companies can monitor and manage electricity connections, preventing non-payment issues and regulating the maximum demand of customers. This ultimately helps stabilize the electricity distribution system.
A key component in ensuring the proper functioning of these systems is the “Latching Relay”. This vital device enables precise control of the smart meter's operations, managing everything from customer demand to energy connection control.
