[Power Supply Design Proposal Example] Replacing Discontinued Products with Our Standard Products

[Power Supply Design Proposal Example] Replacing Discontinued Products with Our Standard Products

Manufactured a power supply with the same specifications! Reduced the lead time for component supply during maintenance and other times!

The manufacturer of the power supply unit we had been using has discontinued production and it has been discontinued, so we received a request to produce a power supply unit with the same specifications. After confirming the specifications of the power supply unit and equipment through hearings, we manufactured a power supply with the same specs. By replacing components such as electronic parts with our standard products, we shortened the lead time for supplying parts during maintenance. [Challenges] ■ The manufacturer of the power supply unit we had been using has stopped production and it has been discontinued. ■ We would like to have a power supply unit with the same specifications produced. *For more details, please refer to the related link page or feel free to contact us.

[Power Supply Design Proposal Example] Development of Power Supply Equipment for Use in Extremely Cold Regions

[Power Supply Design Proposal Example] Development of Power Supply Equipment for Use in Extremely Cold Regions

The key point is whether it can operate normally within the required temperature range! The design takes into account the variations in temperature of the components!

The customer in this case is aiming to develop a power supply for industrial machinery to be used in extremely cold regions and has requested a design for a power supply that can operate at -30°C. We will change semiconductors such as ICs and capacitors to low-temperature compatible components. When used in extremely cold regions, the key point is whether the device can operate normally within the required temperature range, as the characteristics of electronic components can change with temperature. For example, capacitors can have their capacitance halved at lower temperatures, which may prevent achieving the intended effect, so we designed with consideration for the variation of components due to temperature. [Challenges] ■ Development of a power supply for industrial machinery to be used in extremely cold regions ■ Request to design a power supply that can operate at -30°C *For more details, please refer to the related link page or feel free to contact us.

[Power Supply Design Proposal Case] Shortening Development Time by Library Creation of Design Specifications and Drawings

[Power Supply Design Proposal Case] Shortening Development Time by Library Creation of Design Specifications and Drawings

Expand the design of similar specifications and shorten the design lead time! Address the development period within 3 months, including evaluation!

We received a request from the customer to shorten the development period for the power supply unit. Normally, it takes about 6 months to go from design to manufacturing and evaluation for a 1 to 2-channel power supply unit, but this time they inquired whether it could be done in 3 months. Our company has a system in place to shorten the design lead time by creating a library of design specifications and drawings. In this case, we were able to shorten the design lead time by developing a design with similar specifications, allowing us to complete the development period, including evaluation, in 3 months. [Challenges] ■ We want to shorten the development period for the power supply unit (we would like it to be completed in 3 months) - For a 1 to 2-channel power supply unit Normally: It takes about 6 months from design to manufacturing and evaluation. *For more details, please refer to the related link page or feel free to contact us.

[Power Supply Design Proposal Case] Ensuring Heat Dissipation Performance and Miniaturization

[Power Supply Design Proposal Case] Ensuring Heat Dissipation Performance and Miniaturization

Innovative shape! By achieving this without adding a cooling fan, it is possible to miniaturize the power supply!

The customer had designed and manufactured a power supply of 24V 3.5A with an input of AC/DC 100V at a width of 50mm. Due to the specifications of the equipment, it was necessary to change the width to 27mm, but there were concerns about heat dissipation performance, and they consulted us. By innovating the shape of the heat sink and considering the opening position of the cover, we were able to improve the heat dissipation efficiency even at 27mm and ensure the performance of the power supply. Additionally, by achieving this without adding a cooling fan, we were able to miniaturize the power supply.

AC/DC power supply unit for power plants

AC/DC power supply unit for power plants

We proposed a change in the shape of the power supply unit, making it possible to fit within the effective space.

This is a case study of a slot-type power supply unit compatible with AC/DC input for public equipment. With the installation of a no-fuse breaker, there was a challenge in fitting the circuit configuration within the space required by the customer. However, we proposed a change in the shape of the power supply unit, making it possible to fit within the effective space. Additionally, it was designed to allow for the replacement of components with a limited lifespan, such as capacitors. Although the breaker is mounted outside the enclosure, structural measures have been implemented, such as adding a cover, to prevent human error from inadvertently activating the switch. [Case Overview (Excerpt)] ■ Application: Monitoring device ■ Input Voltage Range - AC100/110/115V (AC85V to 127V) - DC100/110/125V (DC80V to 163V) ■ Output Specifications: 5V/15A, 15V/1A, -15V/1A, 24V/3A *For more details, please refer to the related link page or feel free to contact us.

DC power supply device for large analytical instruments

DC power supply device for large analytical instruments

Processing after implementing countermeasures! Introducing examples that address concerns about fluctuations in power supply voltage.

This is a case study on the design and development of a DC power supply for large analytical devices. The output voltage is high, ranging from -8kV to +8kV, and there were concerns about fluctuations in the power supply voltage due to environmental factors, including humidity. There was a request to develop a power supply unit that addresses these issues. To prevent the effects of humidity, the circuit board was housed inside a stainless steel enclosure, and the area around the board was potted with insulating material to mitigate concerns about voltage fluctuations. Additionally, this design made it impossible for operators to physically access the circuit board, thereby enhancing safety. 【Case Overview】 ■ Application: Large analytical devices ■ Input Voltage Range: DC24V ±10% ■ Output Specifications: -8kV to +8kV ■ Number of Channels: 1 channel ■ Efficiency: Not specified *For more details, please refer to the related links or feel free to contact us.
