Industrial Rectifier

Railway Transportation Infrastructure (Indonesia) – 110VDC 60A Parallel Redundant Rectifier System Design and Manufacturing

The 110VDC 60A Industrial Rectifier System commissioned in Indonesia in 2023 is a 4-unit parallel redundant solution specially designed for the uninterrupted power supply of switch motors on the railway line. In the event of a failure, backup systems are activated within milliseconds.

Project Details

In this project successfully completed in 2023 in Indonesia, we designed and manufactured a 110VDC 60A Industrial Parallel Redundant Rectifier System for the uninterrupted power supply of railway switch motors, one of the most critical components of the railway transportation line.

Switch change mechanisms in rail systems must operate with zero tolerance to ensure travel safety and uninterrupted line flow. An advanced architecture consisting of 4 rectifier units in total was established to completely eliminate possible failure risks and ensure the system continues to operate even in extraordinary circumstances.

The system shares the load in a balanced manner with 2 active parallel operating units, while guaranteeing full safety with 2 redundant units. In the event of a fault in one of the active units, the backup systems take over within milliseconds without any interruption. This redundant architecture minimizes fault management on the railway line and delivers maximum line safety.

System Technical Specifications:
- 3x400VAC / 110VDC 60A Input/Output
- 2 Active Parallel + 2 Redundant Topology
- IP21 Protection Class — RAL 7035
- Dimensions: 1000×1200×1900mm
