Train Inverter 220W

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.

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


• Isolation: 3000 Vrms input-output; output failure alarm; remote inhibit; efficiency up to 89%


• Cooling: natural convection — fully fanless, no moving parts; dimensions 100×220×40 mm, weight 900 g


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

In railway train applications, this inverter powers onboard AC loads such as passenger lighting, HVAC controls, information displays, and door control systems. It complies with EN 50155 requirements for electronic equipment used in rolling stock, withstanding the wide input voltage fluctuations and transient disturbances typical of 24 V, 72 V, and 110 Vdc train bus systems. The fanless, vibration-resistant design ensures reliable long-term operation in passenger coaches and commuter trains.
