Electrical Equipment for Railcars

Auxiliary Power Supply System (APS)

Fuji Auxiliary Power Supply Line Up

Fuji's APS will be satisfied with various requirement.

Large Capacity APS for DC Cars with 3-Level Inverter

  • Less acoustic noise and less EMI with 3-level inverter

  • Larger capacity with small size

Typical specifications ;

Input Voltage DC1500V
Output Voltage AC440V 3φ 50/60Hz
Output Capacity 120kVA 180kVA 210kVA 260kVA

APS for AC Cars with IGBT PWM Converter

  • More stable DC link voltage by using IGBT PWM converter

Typical specifications ;

Input Voltage AC440V DC1500V
Output Voltage AC100V 1φ 50/60Hz AC440V 3φ 50/60Hz
Output Capacity 20kVA 180kVA

Small Size and Light Weight APS for Small Cars

  • Medium frequency isolation system with forced-air cooling makes equipment smaller and lighter

Typical specifications ;
