Mining 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.

In mining and heavy industry applications, this inverter powers control electronics, sensors, communication systems, and safety equipment on mining vehicles and underground machinery operating from 24 V to 110 Vdc battery systems. Its sealed, fanless construction resists dust ingress and condensation in the wet, corrosive environments of underground mines and open-pit operations. Meets the stringent reliability demands of continuous-duty industrial equipment subject to high mechanical stress.
