Built on our all-compatible drive architecture these inverter modules are designed to fit all your cabinet requirements. The modules come in eight frame sizes, including the R8i inverter module for building high power inverters in multidrives. The R8i has a speed-controlled fan, quick connectors and wheels for easy maneuvering. Built-in capacitors smooth the voltage of the DC busbars, while safety is key with safe torque off (STO) as standard.
