Railway vehicle ultra-wide range DC input power supply device

Railway vehicle ultra-wide range DC input power supply device

No manual switching of the input power supply voltage! Continuous input is achieved through innovations in the control circuit.

This is a case study of a DC/DC converter (module for VME 3U size) that supports ultra-wide input. At the customer's request, they wanted to cover multiple models with DC24V/48V/72V/110V, but due to cost issues and the complexity of purchase management, they consulted about wanting to consolidate into one model. Additionally, for overseas products, it was necessary to switch control circuits for each input voltage range. By innovating the control circuit, we achieved continuous input of DC24V/48V/72V/110V without the need for manual switching of the input power supply voltage. 【Case Overview】 ■ Application: Railway safety equipment ■ Input voltage range: DC24V/48V/72V/110V (DC16.8V to 138V) ■ Output specifications: 3.3V/10A ■ Number of channels: 1 channel ■ Efficiency: 65% or more ■ Size: 40W × 129H × 233D ■ Applicable standards: JIS E 5006, JIS E 4031, IEC62236-3-2, IEC61000-4-2, IEC61000-4-11, JIS C 60068-1, VME compliant, etc. *For more details, please refer to the related link page or feel free to contact us.

AC/DC power supply unit for communication base stations

AC/DC power supply unit for communication base stations

Achieved cost reduction! Designed and developed power supplies that were originally manufactured for the domestic market for overseas use.

This is a case study of a power supply for overseas communication base stations (module for VME 6U size). For domestic use, we had produced two types of power supplies, but for overseas use, there was a request to produce one type that could be used for two different applications. However, making it a dual-purpose specification required an increase in output by 10%, which raised concerns about cost. Therefore, we removed lower-priority functions and simplified the design to achieve a lower cost. [Case Summary (Excerpt)] - Application: Railway/Communication Base Station - Input Voltage Range: AC100/110V (AC80V to 132V) - Output Specification: 5V/22A - Number of Channels: 1 channel - Efficiency: 65% or more *For more details, please refer to the related link page or feel free to contact us.
