spittler electrical components Germany spittler model spittler price

spittler electrical components are electrical control devices. When the change in the input quantity (excitation) meets specified requirements, they cause a predetermined step change in the controlled quantity in the electrical output circuit. They facilitate interaction between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). Typically applied in automated control circuits, they function as "automatic switches" that use small currents to control large currents. Therefore, they serve functions such as automatic regulation, safety protection, and circuit switching in electrical circuits. A relay is an electrical control device that, upon receiving a specified input quantity maintained for a sufficient duration, causes a predetermined step change in the controlled quantity in the electrical output circuit. When the input quantity drops to a certain level and is maintained for a sufficient duration, the device returns to its initial state.

A solid-state relay consists of three parts: the input circuit, isolation, and the output circuit. Depending on the input voltage category, input circuits can be classified into DC input circuits, AC input circuits, and AC/DC input circuits. Some input control circuits are compatible with TTL/CMOS, featuring positive/negative logic control and inversion, allowing convenient connection to TTL and MOS logic circuits. For control signals with fixed control voltage, resistive input circuits are used. Isolation and coupling between the input and output circuits of solid-state relays are achieved via optocoupling or transformer coupling. Optocoupling typically uses photodiode-phototransistor pairs, photodiode-triac optoisolators, or photovoltaic cells to isolate control from load sides. High-frequency transformer coupling utilizes self-excited high-frequency signals generated by the input control signal, coupled to the secondary side, then demodulated, rectified, and processed by logic circuits to form drive signals. The power switch of the solid-state relay connects directly to the power supply and load terminals to switch the load power on and off. Main components include high-power bipolar transistors, SCRs, triacs, power MOSFETs, and IGBTs. The output circuit of a solid-state relay can also be categorized into DC output, AC output, and AC/DC output types. Based on load type, they are divided into DC solid-state relays and AC solid-state relays. For DC output, bipolar devices or power MOSFETs are used; for AC output, two SCRs or one triac are typically used. AC solid-state relays are further divided into single-phase and three-phase AC solid-state relays. Based on turn-on and turn-off timing, AC solid-state relays are classified as random-turn-on and zero-crossing types.

Main potentiometer parameters include nominal resistance, rated power, resolution, sliding noise, resistance variation characteristic, wear resistance, zero-position resistance, and temperature coefficient. 1. Rated power: The maximum power allowed to be dissipated across the two fixed terminals of a potentiometer is its rated power. Note that rated power does not equal the power between the wiper and a fixed terminal. The rated power of a potentiometer refers to the maximum power allowed for continuous long-term operation at the specified rated temperature in DC or AC circuits when atmospheric pressure is 87~107kPa. 2. Nominal resistance: The nominal resistance marked on the product, with series similar to resistor series. 3. Tolerance class: The error range between measured resistance and nominal resistance allows for 20%, 10%, 5%, 2%, 1% errors depending on precision class. Precision potentiometers can achieve accuracy up to 0.1%. 10. Resistance variation law: Refers to the relationship between resistance and the rotation angle (or sliding travel) of the wiper contact. This relationship can take any functional form; common types include linear, logarithmic, and reverse logarithmic (exponential). In application, linear potentiometers are suitable as voltage dividers; reverse logarithmic (exponential) potentiometers are suitable for volume controls in radios, recorders, phonographs, and televisions. If replacements are unavailable during maintenance, linear types may substitute, but logarithmic types are not recommended. Logarithmic potentiometers are only suitable for tone control, etc.

The basic structure of a voltage transformer is very similar to that of a transformer. It also has two windings: one called the primary winding and the other called the secondary winding. Both windings are mounted on or wound around the iron core. Insulation exists between the two windings and between the windings and the iron core, providing electrical isolation. During operation, the primary winding N1 is connected in parallel to the line, and the secondary winding N7 is connected in parallel to instruments or relays. Therefore, when measuring voltage on high-voltage lines, although the primary voltage is high, the secondary voltage is low, ensuring the safety of operators and instruments.
