Saia-Burgess electrical component parameters

1. Stable voltage refers to the stable voltage value generated across the terminals when the Zener diode passes the rated current. This value changes slightly with operating current and temperature. Due to differences in manufacturing processes, the stabilization voltage of Zener diodes of the same model is not completely consistent. 2. Reverse leakage current refers to the current passing through the Zener diode when it generates a stable voltage. Below this value, although the Zener diode can still stabilize voltage, the stabilization effect will deteriorate; above this value, as long as the rated power dissipation is not exceeded, it is also allowed, and the stabilization performance will be better, but it will consume more electrical energy. 3. Dynamic resistance refers to the ratio of the voltage change to the current change across the Zener diode terminals. This ratio changes with different operating currents; generally, the larger the operating current, the smaller the dynamic resistance. 4. Rated power dissipation is determined by the allowable temperature rise of the chip, and its value is the product of the stable voltage and the maximum allowable current. 5. The temperature coefficient means that if the temperature of the Zener diode changes, its stable voltage will also undergo slight changes. The relative change in voltage across the tube terminals caused by a temperature change of 1℃ is the temperature coefficient (unit: %/℃). Generally speaking, stabilization voltages below 6V belong to Zener breakdown, and the temperature coefficient is negative; the temperature coefficient is positive. When the temperature rises, the depletion layer decreases. In the depletion layer, the valence electrons of atoms rise to higher energy levels, and a smaller electric field strength can excite valence electrons from atoms to produce Zener breakdown, so its temperature coefficient is negative. Avalanche breakdown occurs when the depletion layer is wider and the electric field strength is lower. An increase in temperature increases the vibration amplitude of lattice atoms, hindering the movement of carriers. In this case, only by increasing the reverse voltage can avalanche breakdown occur, so the voltage temperature coefficient of avalanche breakdown is positive. For occasions with high requirements for power supplies, two Zener diodes with opposite temperature coefficients can be connected in series for compensation. Due to mutual compensation, the temperature coefficient is greatly reduced. 12. Reverse leakage current refers to the leakage current generated by the Zener diode under the specified reverse voltage.

Saia-Burgess electrical component principles

The diesel engine drives the generator to operate, converting the energy of diesel into electrical energy. Inside the diesel engine cylinder, clean air filtered through the air filter mixes fully with high-pressure atomized diesel injected from the nozzle. Under the compression of the upward-moving piston, the volume shrinks, and the temperature rises rapidly, reaching the ignition point of diesel. The diesel is ignited, the mixed gas burns violently, the volume expands rapidly, pushing the piston downward, known as "work". The gasoline engine drives the generator to operate, converting the energy of gasoline into electrical energy. Inside the gasoline engine cylinder, the mixed gas burns violently, the volume expands rapidly, pushing the piston downward to perform work. Whether it is a diesel generator or a gasoline generator, each cylinder performs work sequentially in a certain order. The thrust acting on the piston becomes the force driving the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. By installing the brushless synchronous AC generator coaxially with the prime mover crankshaft, the rotation of the prime mover can drive the rotor of the generator. Using the principle of 'electromagnetic induction', the generator outputs induced electromotive force, and current can be generated through the closed load circuit.

Saia-Burgess electrical component parameters

Rated voltage: refers to the safe voltage allowed when the switch is working normally. If the voltage applied across the switch terminals exceeds this value, it will cause sparking 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 be burned 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 open state. Withstand voltage: 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.
