Metro 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 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.
