Metro 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 metro and subway rolling stock, this inverter delivers clean sinusoidal AC power for safety-critical onboard systems including emergency lighting, communication equipment, and door control electronics from 24 V to 110 Vdc battery backup systems. Its high efficiency and wide operating temperature range suit the demanding duty cycles of metro vehicles running up to 20 hours per day. Fully compatible with underground EMI requirements and EN 50155 Class OT4 temperature profiles.
