Why are latching relays popular in the energy meter market?
In the current era of rapid industrial development, with the development of energy meters, it has also ushered in rapid development. Relays have become an indispensable and important component in electric energy meters. They have the characteristics of strong load capacity, small size, high input and output isolation, low power consumption and low temperature rise. They have a high market share and are widely used. They are highly favored by producers and will inevitably bring prosperity to the industry.
The magnetic latching relay was originally used mainly in IC card prepaid meters and centralized meter reading systems. In recent years, magnetic latching relays have been widely used in composite switches of reactive power compensation devices. In composite switches, they are used in conjunction with thyristors and become the main switching devices in reactive power compensation devices to switch high current circuits. They can also be used in various home appliances and automatic control devices (such as smart home control systems, industrial control systems, etc.)
The magnetic latching relay is an electronic control device with a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is usually used in automatic control circuits. In fact, it is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. The magnetic latching relay currently has a broad development prospect in the market and is widely used in the market. It is an industrial general relay, as the most commonly used relay type, and is widely used in various fields of the national economy. Including construction, transportation, energy, industry, etc., there are applications of safety, time, and monitoring relay products. Relays are indispensable in any field of automated control and are favored by users.
With the development of electric energy meters, magnetic latching relays have become an indispensable and important component in electric energy meters. In order to cooperate with the installation and use of electric energy meters, they are required to have the characteristics of small size, strong load capacity, high input and output isolation, low power consumption, low temperature rise, etc. Their main technical indicators are also used in different environments. There are higher requirements for the setting and reset voltage, contact circuit, dielectric withstand voltage, coil power consumption, impact current, and temperature rise of the lead-out end of the magnetic latching relay to ensure its reliability and safety. This means quality control of the production process, materials, and tooling of magnetic latching relays.
Due to the advancement of science and technology, ordinary electric meters are gradually replaced by intelligent electric meters, thus realizing functions such as remote control and remote charging. Magnetic latching relays have been widely used in this field, especially dual-phase latching relays. There are hundreds of manufacturers producing smart meters on the market, and the smart products manufactured by each manufacturer are different, so the requirements for built-in magnetic latching relays are also different. Due to the size limitation, some smart meters cannot be installed in a built-in manner using a single-layer dual-pole latching relay, which is not conducive to installation in narrow places. If it needs to be built-in, the volume of the smart meter must be enlarged, which brings many difficulties to the manufacturer. If the dual-channel magnetic latching relay is designed with a double layer, these troubles can be completely avoided. At the same time, the market demand for double-layer and small-volume dual-channel magnetic latching relays is also greater.
IVY's latest dual-pole latching relay meets the needs of the development of electric meters. It has a built-in 500mT magnetic field immunity function and does not require an iron shield. At the same time, it has a low contact resistance and an auxiliary switch. For more product details, please email to ess1@ivy-metering.com or contact WhatsApp: +86 134 7285 8741
