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
Insulation resistivity is a physical quantity used to express the resistance characteristics of various substances. The resistance of a wire made of a certain material with a length of 1 meter and a cross-sectional area of 1 square meter at room temperature is called the resistance of the material... read more
Resistive load boxes are mainly used for performance testing and aging of online high-power UPS, inverters, switching power supplies and diesel generator sets in electric power, telecommunications and other departments and manufacturers. Unified segmented power input, energy-consumption working mode... read more
When the servo drive is running with a motor, if ALE05 (abnormal regenerative energy) appears on the drive panel, it means that the energy generated by the motor regeneration exceeds the energy consumed by the built-in regenerative resistor of the drive. At this time, a regenerative resistor must be... read more
In actual electronic work, how to quickly find the resistance value of the resistor you want can improve work efficiency, which is also a basic skill, but it must be mastered quickly. Color ring resistors are divided into five rings and four rings. There are four colors for the four ring resistors, ... read more
