1. It has high reliability. Because the magnetic latching relay strictly selects military-grade Manganin Copper Shunt components, the reliability of the product is greatly improved. All electrical connection Electrical Silver Contacts are connected by solid parts, and the working power supply of the magnetic latching relay adopts an independent power supply. The various output signals of the magnetic holding relay are isolated and transformed without interfering with each other. The cables connected with various instruments and meters are double-shielded cables. As long as one end is reliably grounded, the interference introduced by the line can be effectively suppressed.

2. The magnetic latching relay with Manganin Shunt Resistor that can protect motors with various starting conditions, and has high operational reliability, such as motor overload and phase failure protection, grounding protection, and can realize centralized computer control, improve the degree of automation of the power distribution system, and make Power distribution, control system scheduling and maintenance reach new levels.

3. The E-beam Welding Shunt magnetic latching relay produced adopts the second-level temperature automatic compensation technology and the optimized circuit structure design technology on the basis of the full current law. According to the principle of center and axis symmetry in the magnetic circuit, the latest materials and process technology are selected. , to ensure the theoretical calculation accuracy requirements of the product in practical applications. The three-stage differential amplifier circuit is adopted to eliminate the error caused by the output resistance of the Hall element being greater than the input resistance of the op amp, so that the sampling value can be reflected without distortion and meet the design requirements.

4. The Bimetal Contact Rivets magnetic latching relay produced is based on the principle of symmetry. The channel air gaps in the closed magnetic circuit are evenly distributed in even numbers, and the technical parameters of the Hall element are strictly matched. The product's anti-external magnetic interference ability is improved, and the secondary temperature automatic compensation technology is adopted, so that the product is not affected by the external ambient temperature and the offset changes. The fully enclosed anti-corrosion and dust-proof measures are adopted, but the Hall element in the air gap is not sealed, in order to avoid that if a certain Hall element is damaged and cannot be replaced, even if a false value is adjusted without stress on the circuit, the symmetry is completely lost. principle, so the influence of eccentric error cannot be guaranteed.
