As the name suggests, a single-phase plug-in card electric meter is a device that uses an electric energy meter by inserting a card. Such devices are often found in student dormitories, hotels, and other places in schools. Its use must be achieved by inserting an electronic card, which greatly saves a lot of energy resources and brings about cost savings. Single phase plug-in card meter is a type of energy metering meter and also one of the manifestations of prepaid power purchasing systems. Its biggest factor is that it does not require manual meter reading work, which is conducive to modern management and standardization, effectively avoiding the inconvenience and embarrassment of on-site checking of electricity usage.

Single phase card inserted electricity meters allow customers to plan ahead and purchase electricity and usage based on their own usage and needs. This reduces unnecessary expenses and solves the problems of temporary customer electricity usage, scattered merchant electricity usage, and billing, without any delay or delay in electricity bills. The LED digital tube equipped on the energy meter is currently the most popular and environmentally friendly tube in the lighting market, which can display relevant data clearly and accurately, and can be used even in dark environments. In order to improve the user experience and effectiveness, business functions such as alarm tripping and over power reminder have been added.
