Modular DIN Rail Products offer a wide range of functions to be integrated in electrical installations with significant benefits for the user. It is designed for high level performance and are safe and fast to install. Blue Jay have a complete range of DIN-mounted electricity meters for different applications, together with a wide range of communication options. The meters are quick and easy to install due to their DIN-rail mounting. It is highly accurate, durable, reliable, lower power consumptive, without reversion, creep proof, anti-tanmpering and bilateral recoring with strong overloading capability. It conforms to the related Chinese requirement of GB/T17215.321-2008 and International requirement IEC62053-21 also pass EMC and LVD.
