Product Introduction
IVY Metering specializes in the research, development, and manufacturing of high-power and high-quality magnetic latching and motor latching relays for switching purposes. The existing magnetic latching relay driving mechanism is mainly used for integrated smart meter terminal modules or split smart meter terminal modules. The integrated smart meter terminal module fails to take into account that the magnetic latching relay must work normally under a specific constant magnetic field, and cannot prevent interference from external strong magnetic fields.
IVY Metering motor latching relays align with the requirements of the electric power industry's smart grid initiative. IM-M1201T 3-phase relay is designed to provide the highest electrical performance in a compact package. The compact relays utilize innovative technology for accurate switching with low contact resistance. The disconnect relays provide magnet tamper resistance to prevent switching by an external magnetic field as well as safe electrical operation.
It has the following characteristics:
1. Driven by an internal small motor instead of coils drive, saving power and stable performance.
2. Small size, light weight, compact structure, built-in 500mT anti-constant magnetic field.
3. Small contact resistance (less than or equal to 0.5 milliohms)
4. Strong pull-in between contacts and high reliability

TYPICAL APPLICATION：
Mainly used for prepayment electric energy meters, RS485 meters with the break & make function used in meter reading system;
It might also be used for combination switches of electric power factor compensation switch-capacitor, home appliances, and automatic control devices.
If the magnetic latching relay wants to have the ability to resist magnetic field interference, it needs to add an iron shield, which will take up more space and cost more. IVY Motor latching relays are also familiar and used by more and more meter manufacturers because of their gear structure and inherent anti-magnetic properties.
