Single Dual Coil Latching Relay (English name: relay) is an electrical control device, which is an electrical appliance that makes a predetermined step change in the controlled quantity in the electrical output circuit when the change of the input quantity (excitation quantity) reaches the specified... read more
What is a relay? From the definition of a relay, a relay is an automatic control device that will change the output by jumping when the input (electricity, magnetism, sound, light, heat) reaches a certain value. The smart home relay is actually an electronic control device. It has a strong control s... read more
Electromagnetic relay is one of the earliest produced and most smart home relay widely used relays. Electromagnetic relays are usually composed of seven parts: electromagnetic coil, iron core, armature, contact, return spring, bracket and pin. UL & VDE Certification 16A PCB type Smart Home Relay... read more
In the varistor market, although the growth rate of through-hole lead products is much slower than that of SMT products, manufacturers expect that the growth rate of through-hole lead varistors will still be between 5% and 10% this year. In the U.S. market, demand for through-lead varistors still ac... read more
There are many types of relays, so how do we classify them? Below we classify the magnetic latching relay according to their working principle, product usage, external dimensions, protection features, contact loads, etc: Classification according to the working principle of relays Electromagnetic Re... read more
Generally speaking, magnetic latching relay are composed of two parts: contacts and coils, so the graphic symbols in the relay circuit diagram also include two parts: a group of contact symbols represents the contact combination; and a rectangular box represents the coil; When not many circuits are ... read more
1. Influence of temperature: Temperature has a great influence on insulation resistance. Generally, insulation resistance decreases with the increase of temperature. The reason is that when the temperature increases, the polarization in the insulating medium intensifies, which increases the conducta... read more
Industrial control relays are common smart home relay in the industry. Generally speaking, a relay relay is an automatic control electrical appliance that acts according to a specific input signal. There are many types of relays, and there are time relays. Usually refers to the symbol of a contactor... read more
The regenerative resistor is the first internal word of Taiwan-funded enterprises, and now it has become a common word in the inverter industry and the server industry. In fact, the regenerative resistor is in the system where the inverter drives the motor. It is realized by small frequency. At the ... read more
