Light-rail 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 light rail transit (LRT) systems, this inverter supplies AC auxiliary power for passenger comfort systems, real-time passenger information displays, and onboard surveillance equipment. Compatible with the 24 V, 48 V, and 72 Vdc supply rails found in modern light rail vehicles, it tolerates the rapid voltage variations caused by regenerative braking and acceleration loads on the traction network.
