690V VFD

Engineered for extreme operating conditions and heavy continuous loads, our 690V Class Industrial VFDs (18.5kW to 93kW / 25HP to 125HP) operate on high supply voltages to drastically reduce operating current, minimizing cable sizing and transmission heat losses over extended cable lengths. Featuring reinforced IGBT thermal margins, torque limiting, and rugged enclosures, they provide unyielding reliability for underground mining conveyors, slurry pumps, ball mills, petrochemical pipelines, and marine deck machinery.

Renhotec also offer:

• • Economic VFDs: Space-saving micro drives (0.75kW–2.2kW) designed for OEM packaging lines, conveyors, and compact automation.

  • General Purpose VFDs: Heavy-duty vector drives (4kW–220kW) providing 150% starting torque for extruders, industrial pumps, and fans.

  • 1-Ph 220V Input to 3-Ph 380V Output VFDs: Boost single-phase 220V utility power into balanced 3-phase 380V output to run heavy machinery without grid upgrades.

  • Solar Pump Inverters: Hybrid DC/AC solar variable speed drives with built-in MPPT for zero-emission agricultural irrigation.
