Light-rail 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 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.
