Locomotive Inverter 3000W

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 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.
