Metro 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.
