1. Intelligent solid-state relays are small in size, exquisite in appearance, and can be directly replaced in the same installation position as existing products.
2. Intelligent solid-state relays have the function of automatically sensing the external environment and the working status of the equipment. When the control load changes, such as leakage of the load and increase of the working current, local short circuit or change in the heat dissipation conditions, the temperature of the intelligent solid-state relay body rises rapidly and overheats. Generally, 80% of the failure forms of solid-state relays are overheating damage, and the intelligent solid-state relay has the temperature control of the intelligent micro-power control chip inside the device to automatically reduce the conduction current of the power device. If the temperature of the intelligent micro-power control chip inside the device continues to rise, the main current of the entire working system will be automatically shut down, achieving the function of automatic intelligent fault identification. An additional protection measure for the control load can also ensure that the fault will not expand until the fault is eliminated. At the same time, it also protects the power device itself from being damaged by thermal breakdown. This is an invention patent technology pioneered in the field of international power control ICs. This function is particularly important for some rubber and plastic processing industries, explosion-proof requirements, chemicals, printing, dyeing, military industry, etc.
3. Intelligent solid-state relays also have automatic thermal balance function. With this automatic thermal balance function, the intelligent solid-state relay will reasonably design a heat sink suitable for the working environment. It is more cost-effective, energy-saving, reliable and has a long service life than the general power control solution. It is small in size and has a long working life.
4. The intelligent solid-state relay has a wide voltage input control voltage function, and 2.5 to 48V DC can be well compatible with integrated circuits such as computers and single-chip microcomputers.
5. In addition to a working indicator light, the intelligent solid-state relay also has a working (fault) power indicator light. Through this working fault indicator light, we can clearly see the working status of this solid state and the related load. Of course, the signal of this indicator light can also be a set of signals that output the working status of the intelligent solid-state relay and the driven load to the control center to meet the needs of industrial automation production.
6. The working principle of the intelligent solid-state relay is also very different from that of ordinary solid-state relays. It adopts an advanced soft start working mode. It has strong resistance to current shock, especially in some composite load conditions, it can work reliably, such as capacitive loads.
7. The intelligent solid-state relay has good anti-electromagnetic interference function (EMC). After testing, it only generates less than 10% of the electromagnetic waves of ordinary solid-state relays, not to mention conventional electromagnetic relays. This is of great significance for some specific equipment in industry and military industry. It also greatly reduces the requirements for computer and PLC control equipment.
8. The DBC packaging technology used in intelligent solid-state relays can have 20% more heat capacity than conventional plastic-sealed devices. This is very beneficial, which also increases the power density of the device in disguise.
9. The intelligent solid-state relay body has good heat dissipation function and is the product with the largest heat dissipation area on the market.
Our intelligent solid-state relays have a PK with similar foreign products. They are comprehensively superior. More reliable and safe.
