Telecom 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 telecom and data infrastructure applications, this inverter provides regulated AC power for network equipment, UPS bypass loads, and AC-powered instruments in 48 Vdc or 24 Vdc telecom power environments. The pure sine wave output ensures compatibility with switch-mode power supplies used in routers, servers, and base station equipment. Its low harmonic distortion (THD <3%) prevents interference with sensitive telecom signal processing hardware.
