Technical points.

1.  Magnetic system: the patented technique is a smart and cleverish designed system which works with the structure of metal spiral-like magnetic shielding system without external electron magnetic interference. What's more, the fast push-pull effort of instaneous operation is fierce. Meanwhile, it owes trusted ability of resisting vibration and impact force as well as steady magnetic lock. The mechanical loss during its linear reciprocating operation is very little.

2.  Contact operating system: it has very little mechanical loss due to its reform from inefficient swing-out lever operation to linear reciprocating operation. The use of the two-way flexible gap-free floating operation in its moving contact effectively reduces its contact bounce and extends the using life of contact. The big contact separating brake clearance effectively ensure the safely of the electrical properties; high contact close-brake pressure and lower voltage at rated load (<60mv) and lower temperature conductivity.

3.  Magnetic latching relay pulse trigger parameters: the pulse amplitude and width rely on the accurate parts processing. The perfect manufacturing technique effectively ensures the long-term stability of the pulse trigger parameters of the magnetic latching relay.

4.  Its mechanical-electrical integration system design and its internally installed circuits of commutations, boost pressure, stored energy and relay driving make the energy meter convenience, safe and reliable.
