Tram Inverter 4000W

The ODS-3000 is a high-power single-phase DC/AC inverter delivering 2400–4000 W with selectable 120 or 230 Vac output. Accepting input voltages from 24 to 300 Vdc, it covers one of the widest input ranges in its class. All standard models comply with EN50155 for rolling stock.

Two-stage cascade topology (DC/DC + DC/AC), 3000 Vrms isolation, efficiency up to 91%. Maximum average power and peak current protection, input under-voltage disable, RS232 (PAM Tool), and isolated solid-state relay contacts. Accessory: ACI-3000 inrush current limiter.

• Output: 2400–4000 W, 120 or 230 Vac single-phase pure sine wave, selectable 50/60 Hz, adjustable output voltage


• Input: 7 voltage versions — 24, 36, 48, 72, 110, 120, 300 Vdc (covers low-voltage batteries to high-voltage DC bus)


• Control & monitoring: RS232 remote control; alarm by isolated relay contacts; remote off opto-coupled; remote inhibit


• Isolation: 3000 Vrms; efficiency up to 91%


• Standards: EN50155 railway version (optional); EN45545-2 fire & smoke certified

In tram and urban light rail applications, this inverter provides stable AC power for onboard electronics, passenger display systems, and auxiliary equipment operating from the tram's 24 V or 72 Vdc supply rail. It meets the shock and vibration requirements of EN 61373 for railway rolling stock equipment, making it suitable for both high-floor and low-floor tram vehicles operating in city center environments.
