Light-rail Inverter 220W

The OPS-260 is an IP66-rated ruggedized DC/AC inverter rated 180–220 W with pure sine wave output, for outdoor, defense, and railway applications where a standard enclosure cannot survive. Its sealed 67×249×135 mm housing (1.74 kg) is impervious to dust and high-pressure water jets.

Natural convection cooling — fully fanless — maximises reliability where maintenance access is limited. Input 12 to 110 Vdc, selectable 120 or 230 Vac output, 3000 Vrms isolation. Optional EN50155 railway version and EN45545-2 compliance available.

• Input: 6 voltage versions — 12, 24, 36, 48, 72, 110 Vdc (operating range 9.5–138 V); startup ≤10.2 V


• Dimensions & weight: 67×249×135 mm, 1.74 kg; convection cooling — fully fanless; output failure alarm; remote inhibit


• Standards: EN50155 railway version (optional); EN45545-2 fire & smoke certified; isolation 3000 Vrms

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.
