DC-DC converter SPB05 5W in SIP package

11.07.2015

Mean Well has developed a new series of 5W DC-DC converters with output voltage stabilization - SPB05. The uniqueness of the series is the "packaging" of 5 watts of power in the SIP-8 package. As a rule, DC-DC converters with the specified power are already manufactured in a DIP-24 package. A feature of the SIP-8 package compared to the DIP-24 is a significantly smaller footprint on the board (about 1/3).

The SPB05 series converters have a 2:1 wide input voltage range, 1500 V input-output dielectric strength, short circuit and overload protection, remote On-Off capability and are operable in a wide temperature range of -40°C...+80°C.

The new SPB05 series of converters is designed for a variety of industrial and telecommunication applications, as well as for any other application that requires compact size and increased power over a wide temperature range.

Main technical parameters of SPB05 series:

- output power: 5 W;
- case type: SIP-8;
- dielectric strength of insulation: 1500 V;
- output voltage from the series: 5, 12, 15 V;
- input voltage range from a range: 9-18, 18-36, 36-72 V;
- protection against short circuit and overload.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Speed sensor VG481V1 13.08.2020

The new VG481V1 sensor from Honeywell is designed to measure the speed of rotation of a ferrous metal gear.

The sensor allows you to detect the fact of the passage of a gear tooth. The moving gear tooth changes the magnetic field created by the bias magnet, which is recorded by the Hall sensor. With dual-peak detection circuitry, the VG481V1 can measure the speed of the gear with high reliability.

The VG481V1 speed sensor is used in automotive transmissions and, in general, is applicable in any transmission and mechanisms where it is necessary to monitor the rotation of a ferrous metal gear.

The VG481V1 includes a voltage regulator, a clock generator, a Hall element, an amplifier, a high and low detection circuit, a comparator, and an output stage. The sensor is protected from abnormal operation at voltages below the minimum threshold, the output of the microcircuit is resistant to short circuits.

The power circuit is insensitive to reverse voltage polarity. When power is applied to the sensor, the trigger circuit does not allow operation until a stable reading is established. VG481V1 allows you to define zero rotation speed.

The sensor is available in a slim size TO-92.

The main parameters of the Hall sensor VG481V1:

Rotation speed measurement;
Zero speed fixing;
Low price and simple inclusion;
Supply voltage from 4 to 24 V;
Operating temperature -40 to 150°C;
Output current up to 20 mA (open collector);
Output short circuit protection;
Reverse polarity protection;
Certified by AEC-Q100 (Grade 0).
