Metro Inverter 1300VA

The ODX-1300 is a three-phase sinusoidal DC/AC inverter rated 1300 VA with multiple input-output voltage combinations. It accepts 24, 72, or 110 Vdc and provides 250 or 400 Vac three-phase output, supporting motor control and auxiliary three-phase loads. Compliant with EN50155 and EN45545-2.

Galvanic isolation 3000 Vrms, efficiency up to 91%, adjustable output frequency 5–60 Hz via RS232 (PAMTool). Input under-voltage disable, flat chassis with 4 threaded holes for quick installation.

• Output: 1300 VA three-phase pure sine wave — 250 Vac or 400 Vac (with or without neutral), suitable for motor control


• Input: 3 voltage versions — 24, 72, 110 Vdc (operating range 16.8–138 V)


• Control & monitoring: RS232 remote control; alarm by isolated relay contacts; remote ON/OFF opto-coupled


• Isolation: 3000 Vrms; adjustable output voltage


• Standards: EN50155 (standard, not 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.
