Product Introduction
Both IM901D and IM902D are 2-pole latching relays with MAX current up to 90A, and switching 90A 250VAC. Single and Double coil optional. The main advantages of the two groups of relays include long life, high reliability, high sensitivity, low power consumption, good electromagnetic compatibility, fast switching, and low electromagnetic interference.
The difference between these two relays is the connection method: IM901D is PNNP type, IM902D is PPNN type. Widely used in smart meters, EV chargers, street lighting control systems, and industrial automation.

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.
