[Power Supply Design Proposal Example] Unitization by Output Voltage to Reduce Running Costs

[Power Supply Design Proposal Example] Unitization by Output Voltage to Reduce Running Costs

Addressing concerns such as decreased safety! Individual unitization allows for quick and low-cost repairs!

We received a request from a customer to develop a power supply unit capable of high current output, such as 200-300A, with multi-channel output. There are concerns about rising maintenance costs and decreased safety due to the inability to manage channels individually if the multi-channel outputs are integrated. We also received a request to address these issues. By creating a separate output unit for each output voltage and combining them, we can accommodate individual management. By individualizing the units, repairs can be done quickly and at low cost, which can also help reduce running costs. [Challenges] ■ Development of a power supply unit capable of high current output, such as 200-300A, with multi-channel output ■ Concerns when integrating multi-channel outputs - Increase in maintenance costs - Decreased safety due to inability to manage individually - Need to replace the entire power supply unit in case of failure *For more details, please refer to the related link page or feel free to contact us.

Power Supply Design Proposal Example: Comprehensive Support Until Development of Inspection Equipment

Power Supply Design Proposal Example: Comprehensive Support Until Development of Inspection Equipment

We implemented VA/VE proposals to address the issues that had arisen! Here’s a case study that received great satisfaction!

The power supply of a special inspection device within the power plant has failed, and since it is a discontinued maintenance item, the manufacturer is unable to respond, leading to a consultation with our company. Upon hearing the situation, it was noted that there were requests not only for the replacement of the power supply unit but also for improvements to the inspection device, and they requested that we handle the replacement of the inspection device. In this case, we addressed not only the power supply unit but also the replacement of the existing inspection device, and we implemented VA/VE proposals to address the issues that had previously occurred. By providing a consistent response from the power supply unit to the testing device, we were able to reduce the burden on the customer, resulting in a highly satisfactory case. [Challenges] ■ The power supply of a special inspection device within the power plant has failed. ■ It is a discontinued maintenance item, and the manufacturer is unable to respond. ■ There are requests for improvements to the inspection device, not just for the replacement of the power supply unit. ■ They would like us to handle the replacement of the inspection device. *For more details, please refer to the related link page or feel free to contact us.

[Power Supply Design Proposal Example] Ultra-wide range support for input DC 24V to 110V.

[Power Supply Design Proposal Example] Ultra-wide range support for input DC 24V to 110V.

By eliminating the switch, it is possible to achieve stable output! Reliability has also improved!

We received a request from a customer to develop a power supply with an ultra-wide input voltage range of 12 to 110V. Typically, when the range is wide, it is necessary to separate the power supply by input voltage, such as 12 to 24V or 48 to 72V, or to use a switch to toggle between them. By using a buck-boost switching converter that can automatically switch between boost and buck operations, we can accommodate an ultra-wide input range of DC 24V to 110V. Eliminating the switch allows for stable output and improves reliability. [Challenges] ■ Development of a power supply with an ultra-wide input voltage range of 12 to 110V ■ When the range is wide - It is necessary to separate the power supply by input voltage, such as 12 to 24V or 48 to 72V - Or it is necessary to use a switch to toggle between them *For more details, please refer to the related link page or feel free to contact us.

[Power Supply Design Proposal Example] Replacing Obsolete Products with Noise-Resistant Design

[Power Supply Design Proposal Example] Replacing Obsolete Products with Noise-Resistant Design

We propose a circuit design and implementation that is resistant to noise! It is operating without any issues!

The customer in this case was using a DC power supply for industrial equipment from another company, but it had many issues and was discontinued. After conducting a failure analysis, we found that the problems were not due to individual components, but rather inherent design flaws, such as poor noise immunity. In response, we proposed a circuit design and implementation that is resistant to noise. Before our design was implemented, the customer experienced frequent troubles, but after using the power supply designed by us, they have been operating without any issues. [Challenges] ■ Used a DC power supply for industrial equipment from another company ■ Had many issues and was discontinued *For more details, please refer to the related link page or feel free to contact us.

[Power Supply Design Proposal Case] Investigation of Failure Causes and Repair Response for Power Supplies from Overseas Manufacturers

[Power Supply Design Proposal Case] Investigation of Failure Causes and Repair Response for Power Supplies from Overseas Manufacturers

Identifying faulty components in power supplies made by overseas manufacturers! Introducing a case where the equipment was investigated on-site.

A malfunction occurred in the power supply unit, and since it is from an overseas manufacturer, we were unable to conduct a failure investigation, so we received a request from your company. As it was an old device, there were no drawings available, so we conducted an on-site investigation of the device to identify the cause of the failure and the faulty components. After identifying the faulty components, we addressed the issue by replacing the relevant parts. [Challenges] ■ Malfunction occurred in the power supply unit ■ Overseas manufacturer, unable to conduct failure investigation ■ No drawings available due to it being an old device *For more details, please refer to the related link page or feel free to contact us.
