ess elektronik electrical components are current fuses that provide overload protection. When a circuit fault or abnormality occurs, the current continues to rise. This rising current may damage certain important devices in the circuit, burn out the circuit, or even cause a fire. If a fuse is correctly installed in the circuit, it will melt and cut off the current when the current abnormally rises to a certain level and temperature, thereby protecting the safe operation of the circuit. With the fuse correctly installed in the circuit, the fuse will melt and cut off the current when the current abnormally rises to a certain level and temperature, protecting the safe operation of the circuit. The fuse invented by Edison was used to protect expensive incandescent lamps at the time. With the development of the times, fuses protect power equipment from damage due to overcurrent and overheating, avoiding serious damage to electronic equipment caused by internal faults.

ess elektronik electrical component features

A solid-state relay is a contactless electronic switch with isolation function. There are no mechanical contact parts during the switching process. Therefore, in addition to having the same functions as electromagnetic relays, solid-state relays also feature logic circuit compatibility, vibration and mechanical shock resistance, unrestricted installation position, good moisture-proof, mildew-proof and corrosion-resistant performance, excellent performance in explosion-proof and ozone pollution prevention, low input power, high sensitivity, low control power, good electromagnetic compatibility, low noise and high operating frequency. There are no mechanical parts inside the solid-state relay, and the structure adopts a potting fully sealed method. Therefore, solid-state relays have advantages such as vibration resistance, corrosion resistance, long life and high reliability. AC solid-state relays adopt zero-crossing triggering technology, have short switching times, and can be applied in high-frequency occasions. Photoelectric isolation is adopted between the input circuit and the output circuit, input power consumption is very low, there is a protection circuit at the output terminal, and the load capacity is strong.

ess elektronik electrical component characteristics

Resolution refers to the ability of a sensor to detect the smallest change in the measured quantity. That is, if the input quantity changes slowly from a non-zero value, the sensor output will not change when the input change value does not exceed a certain value, meaning the sensor cannot resolve this change in the input quantity. The output will only change when the change in the input quantity exceeds the resolution. Usually, the resolution at each point within the full-scale range of a sensor is not the same. Therefore, the maximum change value in the input quantity that causes a step change in the output quantity within the full scale is commonly used as the indicator for measuring resolution. If the above indicator is expressed as a percentage of the full scale, it is called resolution. Resolution has a negative correlation with sensor stability.

ess elektronik electrical component parameters

Rated voltage: refers to the safe voltage allowed when the switch is operating normally. If the voltage applied across the switch terminals exceeds this value, it will cause arcing and breakdown between the two contacts. Rated current: refers to the maximum safe current allowed to pass when the switch is closed. When this value is exceeded, the switch contacts will burn out due to excessive current. Insulation resistance: refers to the resistance value between the conductive part and the insulating part of the switch. Contact resistance: refers to the resistance value between each pair of contacts when the switch is in the on state. Dielectric strength: refers to the highest voltage that the switch can withstand between the conductor and ground. Life: refers to the number of operations the switch can perform under normal working conditions.
