Having been deeply engaged in relay manufacturing for nearly three decades, Chengyuan Chuangke has once again presented an innovative masterpiece.
Recently, Ningbo Chengyuan Chuangke Electronics Co., Ltd. announced the official launch of a new series of magnetic holding relays, further enriching the company's high-end product lineup. As a professional manufacturer in the relay field with over 30 years of experience, Chengyuan Chuangke's newly launched magnetic holding relays draw on the company's expertise in using permanent magnetic materials, improving electromagnetic systems, and precise manufacturing. They aim to provide efficient and energy-saving circuit control solutions for smart grids, new energy systems, smart homes, and industrial automation fields.
Magnetic holding relays are a new type of relay that has developed rapidly in recent years. Their core advantage lies in the "zero power consumption during state retention" - through the action of permanent magnets, the contact state can be switched with just one pulse signal. Even after a power loss, the current on-off state can be maintained by the permanent magnetic force, without the need for a continuous power supply to maintain it. Compared with traditional relays, magnetic holding relays can significantly reduce energy consumption. The measured data shows that their power consumption is more than 99% lower than that of traditional relays, and the standby power consumption can be as low as 0.1W. They have significant advantages in energy conservation and environmental protection.
Zero-power retention technology, empowering diverse application scenarios
Based on over thirty years of relay manufacturing experience, the R&D team has comprehensively optimized the magnetic circuit system of the magnetic holding relay. The product uses high-performance neodymium iron boron permanent magnets, providing stable remanent magnetic flux density, ensuring reliable holding force for the contacts in both open and closed states. At the same time, through precise electromagnetic coil design and magnetic circuit simulation, a pulse-driven fast response has been achieved - a pulse signal of only a few milliseconds is sufficient to complete the state switching, with the action time controlled within 8ms and the reset time within 5ms.
This series of magnetic holding relays features a small size, strong load capacity, excellent electrical durability, and high anti-surge current capability. The electrical lifespan can exceed 100,000 times, and the mechanical lifespan can reach 10 million times. The products are widely used in scenarios such as smart electricity meters, photovoltaic inverters, electric vehicle charging stations, smart lighting, and smart sockets. In the application of smart electricity meters, the magnetic holding relays can achieve remote on-off control, helping power grid operators significantly reduce standby energy consumption; in the new energy system, the products can withstand 1500VDC high voltage and cut off the circuit in milliseconds when an anomaly is detected, providing reliable security for the system.
Strictly control the entire process quality to ensure stability and reliability.
The core of the magnetic holding relay lies in the stability of the permanent magnetic material and the reliability of the magnetic circuit system. Chengyuan Chuangke, relying on nearly three decades of manufacturing experience, strictly controls the quality from the source, selects instrument-grade permanent magnetic materials and high-quality contact materials (silver tin oxide AgSnO2), ensuring that the product has stable contact resistance (≤100mΩ) and high insulation performance. During the production process, the company strictly adheres to the quality policy of "honesty as the foundation, quality as the soul", and uses automated winding, dispensing, and assembly equipment to conduct strict dynamic contact resistance tests, withstand voltage tests, and life verification for each relay.
To meet the demands of high-density PCB layouts and harsh environmental applications, Chengyuan Chuangke's new magnetic holding relay offers various packaging options, including compact DIP packaging and surface mount models. Some products can be optionally equipped with an internal magnetic shielding structure, significantly reducing external magnetic field interference and enabling stable parallel operation in high-density matrix and multiplexing applications. The product's operating temperature range covers -40°C to 85°C, ensuring it can meet the requirements of industrial-level applications.
Tailor services flexibly based on customer needs
Magnetic holding relays are widely used in smart grids, new energy, industrial control, smart home, and other fields. Different applications have different requirements for the coil voltage, contact form, load capacity, package size, and driving method of the relays. The Chengyuan Chuangke R&D team can quickly respond to customer needs and provide single-coil or double-coil designs, various contact forms (one set of normally open, two sets of normally open, one set of conversion, etc.), custom coil voltages, and customized pin layout solutions. The double-coil design realizes state conversion through independent setting/reset coils, with simple and reliable control logic; the single-coil type relies on the switching of current direction to change the magnetic polarity, and can be combined with H-bridge circuits to achieve bidirectional driving, saving circuit board space.
The company's director stated: "The magnetic holding relay is an important strategic product for Chengyuanchuangke to complete its high-end product line and move towards the field of energy conservation and environmental protection. We will continue to drive with technological innovation and base ourselves on our thirty-year manufacturing experience, dedicated to providing more reliable and energy-efficient relay solutions for global customers, and becoming a trustworthy partner."
