Train 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 railway train applications, this inverter powers onboard AC loads such as passenger lighting, HVAC controls, information displays, and door control systems. It complies with EN 50155 requirements for electronic equipment used in rolling stock, withstanding the wide input voltage fluctuations and transient disturbances typical of 24 V, 72 V, and 110 Vdc train bus systems. The fanless, vibration-resistant design ensures reliable long-term operation in passenger coaches and commuter trains.
