Light-rail Inverter 180W

The OCS-260 is a compact single-phase DC/AC inverter rated 180–220 W with pure sine wave output, designed for industrial and railway applications. Featuring natural convection cooling with no moving parts, it delivers quiet, fanless operation and a long service life. Its slim 100×220×40 mm profile and 900 g weight allow installation in tight equipment compartments typical of rolling stock and control cabinets.

The OCS-260 accepts 12 to 110 Vdc input with selectable 120 or 230 Vac output (±5% adjustable) and 50/60 Hz. Galvanic isolation is 3000 Vrms. An optional EN50155 railway version with EN45545-2 fire and smoke compliance is available.

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.
