Recently, Schneider Electric, a global expert in digital transformation in energy management and automation, released the new Harmony SSP1*E single-phase solid-state relay. This solution has the characteristics of long service life, low maintenance cost, high reliability, high-speed and precise control, which can fully meet the efficient and automated production needs of industrial fields such as packaging, injection molding, textiles and heating furnaces, and provide comprehensive safety protection.
As a common electrical control device, relays are widely used in different industries. Traditional mechanical relays use electromagnetic coils and mechanical contactors to control circuit switches, which have problems such as limited service life, response noise, and limited application environment. With the continuous improvement of market requirements for relay performance and the rapid development of technology, solid-state relays have emerged. The Harmony SSP1*E single-phase solid-state relay launched by Schneider Electric uses the on-off characteristics and photoelectric coupling characteristics of semiconductor devices to control the on-off of the circuit. It not only has a fast response speed and can support a larger output load current, but also has a longer product life. This product adopts a single-phase panel installation method, controls the AC circuit through a DC circuit, and can meet the use needs of various industrial equipment such as injection molding machines, dryers and heating furnaces, spinning machines, lithium electric heating thermal oil furnaces and packaging machines.
Specifically, the Harmony SSP1*E single-phase solid-state relay has the following highlights:
Localization: Based on the real pain points of local Chinese users, it is launched by Schneider Electric China Automation R&D Center. Localized R&D and short-chain supply not only better meet the differentiated needs of Chinese users, but also shorten the distance from the laboratory to the market. While improving delivery speed, it helps companies obtain excellent product quality at a controllable cost, thereby reducing costs and increasing efficiency.
High safety: In terms of mechanical safety, Harmony SSP1*E is equipped with transparent protective flip covers at both the input and load ends, which can effectively avoid finger touch risks and ensure safe operation; in terms of electrical safety, Harmony SSP1*E has excellent surge current tolerance and can withstand more than 10 times the rated load current value. The ultra-low leakage current value of less than 1 mA can provide higher protection for circuit stability. In addition, the product also achieves enhanced insulation within the nominal load voltage range, which can ensure that users can use electricity safely when the base plate cannot be grounded or the grounding effect is poor, and comprehensively enhance the safety of product applications.
High adaptability: Harmony SSP1*E supports an ultra-wide operating current range from 0.1A to 125A, and an ultra-wide operating temperature range from -30ºC to +80ºC, which can easily cope with various harsh working environments and cover a wider range of application scenarios. At the same time, the standard LED indicator can observe the working status of the product in real time, and the compliance with more industry standards and multiple authoritative certifications including UL and CE international safety standards can also help overseas companies quickly win the trust of the international market.
Quick response: With the characteristics of optocouplers, Harmony SSP1*E can accurately achieve high-frequency switching control, especially suitable for PID control in temperature control and electric heating systems; the control method of DC input controlling AC load can achieve efficient control of the equipment.
In addition, the Harmony SSP1*E single-phase solid-state relay has clear markings on the control end and the load end to ensure the safety of user wiring; the device supports different connection and installation methods such as panel and rail installation, standard thermal conductive silicone sheet, and has a complete accessory system such as heat sink and mounting rail buckle, which is extremely easy to use.
Solid-state relays are widely used in temperature control, heat treatment, hot air furnace control and other electric heating systems to achieve precise switching control of heaters, heat exchangers and other heating elements. As a technology-innovative enterprise engaged in intelligent food packaging machinery and equipment, packaging systems and various automation control equipment, Jiangsu Shenyi Machinery Co., Ltd. requires precise and sensitive temperature PID regulation control performance when producing automatic coffee capsule packaging machines to ensure the stability of capsule sealing quality. With powerful and safe performance, rich certification and accessory systems, Harmony SSP1*E single-phase solid-state relays perfectly meet customer needs and help companies build reliable and safe automated production equipment while reducing costs; in addition, as a professional company engaged in modified atmosphere packaging and skin packaging equipment, Sichuan Xinzhou Mechanical and Electrical Equipment Co., Ltd. also uses Harmony SSP1*E single-phase solid-state relays to achieve precise sealing temperature control of fresh packaging machines, so as to better preserve fresh products at low temperatures.
Yang Hang, Marketing Director of Schneider Electric Industrial Automation Business China, said: "The new launch of Harmony SSP1*E single-phase solid-state relays further demonstrates Schneider Electric's determination and ability to drive local innovation and enable industrial enterprises to produce safely. In the future, we will continue to adhere to the development strategy of 'In China, for China', seek win-win results, and contribute to the high-quality development of China's industry."
