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.
