ABLSURSUM electrical components German ABLSURSUM models ABLSURSUM prices

ABLSURSUM electrical components are devices that convert other forms of energy into electrical energy and supply it to circuits (electronic equipment). Power sources operate on the principle of electromagnetic induction, generating electricity from renewable sources such as hydropower, wind power, tides, dam water pressure differences, and solar energy, as well as from burning coal and oil residue. A power source is a device that supplies power to electronic equipment, also known as a power supply unit; it provides the electrical energy required by all components in a computer. The magnitude of the power supply, and the stability of current and voltage, directly affect the operating performance and service life of the computer.

ABLSURSUM electrical component parameters

Rated voltage: refers to the safe voltage allowed for the switch during normal operation. If the voltage applied across the switch exceeds this value, arcing and breakdown between the two contacts will occur. Rated current: refers to the maximum safe current allowed to pass through when the switch is closed; if 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 closed state. Dielectric strength: refers to the maximum voltage the switch can withstand between the conductor and ground. Service life: refers to the number of operations the switch can perform under normal working conditions.

ABLSURSUM electrical component performance

Performance of fiber optic connectors, primarily optical performance, In addition, factors such as interchangeability, repeatability, tensile strength, temperature resistance, and number of mating cycles of the fiber optic connector must be considered. 1. Optical performance: Requirements for the optical performance of fiber optic connectors mainly concern the two most basic parameters: insertion loss and return loss. Insertion loss, also known as connection loss, refers to the loss of effective optical power in the link caused by the introduction of the connector. The lower the insertion loss, the better; it is generally required to be no greater than 0.5dB. Return loss refers to the ability of the connector to suppress reflection of optical power in the link, and its typical value should be no less than 25dB. For connectors used in practical applications, the ferrule surface undergoes specialized polishing treatment, which can increase the return loss, generally to no less than 45dB. 2. Interchangeability and repeatability: Fiber optic connectors are universal passive components; for the same type of fiber optic connector, they can generally be combined arbitrarily and reused multiple times, with the additional loss introduced thereby generally being less than 0.2dB. (3) Tensile strength: For assembled fiber optic connectors, the tensile strength is generally required to be no less than 90N. (4) Temperature: General requirements specify that fiber optic connectors must operate normally within a temperature range of -40oC to +70oC. (5) Mating cycles: Fiber optic connectors in use can generally withstand more than l003 mating cycles.

ABLSURSUM electrical component principles

The thermistor will remain in a non-tripped state for an extended period; When the ambient temperature and current are in the c region, the heat dissipation power of the thermistor is close to its heat generation power, so it may or may not trip. For a thermistor at the same ambient temperature, the tripping time decreases sharply as the current increases; At relatively higher ambient temperatures, the thermistor has a shorter tripping time and lower holding and tripping currents. The PTC effect refers to a material exhibiting the PTC effect, namely the positive temperature coefficient effect, meaning that the resistance of this material increases with rising temperature. For example, most metallic materials exhibit the PTC effect. In these materials, the PTC effect manifests as a linear increase in resistance with increasing temperature, which is commonly referred to as the linear PTC effect. Nonlinear PTC effect: Materials undergoing phase transition exhibit a phenomenon where resistance increases sharply by several to more than ten orders of magnitude within a narrow temperature range, known as the nonlinear PTC effect. A considerable variety of conductive polymers exhibit this effect, such as polymer PTC thermistors. These conductive polymers are very useful for manufacturing overcurrent protection devices. Polymer PTC thermistors are used for overcurrent protection. Polymer PTC thermistors are often referred to as resettable fuses (hereinafter referred to as thermistors). Due to their unique positive temperature coefficient resistance characteristics, they are highly suitable for use as overcurrent protection devices. The method of using thermistors is similar to that of ordinary fuses, It is used in series in the circuit. When the circuit operates normally, the thermistor temperature is close to ambient temperature and its resistance is very low, so being connected in series in the circuit does not impede current flow; however, when an overcurrent occurs in the circuit due to a fault, the thermistor's temperature rises due to increased heating power, when the temperature exceeds the switching temperature, the resistance increases sharply instantaneously, and the current in the loop rapidly decreases to a safe value. After the thermistor trips, the current in the circuit is significantly reduced, t is the tripping time of the thermistor. Due to the good design flexibility of polymer PTC thermistors, their temperature sensitivity can be adjusted by changing their own switching temperature (ts), thus they can serve both as over-temperature protection and over-current protection, making them suitable for over-current and over-temperature protection of lithium-ion batteries and nickel-metal hydride batteries. Influence of ambient temperature on polymer PTC thermistors: A polymer PTC thermistor is a direct-heating, step-type thermistor, whose resistance change process depends on its own heat generation and dissipation conditions, therefore its holding current, tripping current, and tripping time are influenced by ambient temperature.
