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
The EBW shunt resistor is made of nickel-chromium or similar alloy vacuum electroplating technology, and the film is deposited on the surface of the white porcelain rod, and the resistance value is adjusted by cutting to achieve the final required precision resistance value. Metal film resistors off... read more
As the name suggests, no inductance means no inductance value. Of course, no here means that the inductive reactance value on the resistor is very small and can be ignored. Generally, it cannot be said that it is completely absent. Such non-inductive resistors are often used in some precision instru... read more
1. Please set the resistance value (P1-52) and capacity (P1-53) of the regenerative resistor correctly, otherwise it will affect the execution of this function. 2. If the user wants to increase the power of the regenerative resistor in parallel, please check whether the resistance value meets the r... read more
Sampling resistors are current sampling and voltage sampling. For current sampling, a resistor with a smaller resistance is connected in series, and for voltage sampling, a resistor with a larger resistance is connected in parallel. This type of resistor is divided according to the function of the p... read more
Phase unbalance in a three-phase system occurs when one or more of the line-to-line voltages in a three-phase system do not match. Three-phase power systems and equipment are designed to operate with balanced phases lines. Line-to-line voltages in three-phase circuits typically differ by a few volts... read more
