Locomotive Inverter 6000W

The OVX-6400 is a 6000 W / 6400 VA three-phase sine wave DC/AC inverter from the Spark Series, designed to draw power directly from the railway catenary. It converts 400–1000 Vdc catenary input into stable 400 Vac three-phase power for onboard locomotive, tram, and metro systems. An active catenary filter protects against input surges up to 3 kW.

Compliant with EN61287-1, EN50155, EN50124-2:2017. Input-output isolation 5200 Vrms. RS232 and CAN BUS interfaces, configurable voltage and frequency, soft-start. Model 7701Z adds 2800 V transient protection per EN50163. Dimensions: 87×430×450 mm; weight <12 kg.

• Output: 6000 W / 6400 VA (8 kW peak), 400 Vac three-phase pure sine wave; adjustable output frequency and voltage


• Input: 400–1000 Vdc catenary (EN50163:2006, EN50124-2:2017); model 7701Z adds 2800 Vpk transient overvoltage protection


• Isolation: 5200 Vrms (vs standard 3000 Vrms) — highest isolation class for high-voltage catenary environments


• Control & monitoring: RS-232 and CAN BUS interface; alarm by isolated relay contacts; remote off opto-coupled; parallelable up to 4 units


• Standards: designed per EN61287-1; EN45545-2 fire & smoke (pending); suitable for locomotive and catenary-fed traction auxiliaries

In locomotive applications, this inverter powers auxiliary AC loads including cab electronics, lighting systems, engine management displays, and communication equipment from the locomotive's 72 V or 110 Vdc battery bus. Built to withstand the extreme mechanical vibration, wide temperature swings, and high humidity conditions encountered in both freight and passenger locomotive operations across diverse railway networks.
