HES880 has three different firmware. One hardware can be configured to operate in three modes:

  • Inverter for traction motor and generator up to 510 kW continuous and up to 760 kW peak electrical power (500 V and cosϕ 0.98)
  • Bi-directional line converter for grid connectivity
  • DC/DC converter for super capacitor or battery interface, up to 620 kW


Complete and compact regenerative drive modules with all important features built-in the drive.

Regenerative drives save energy compared to other braking methods as energy is fed back to the battery or super capacitor.

Does not need external braking devices, which makes drive installation simple.

The active supply unit can boost output voltage, which ensures reliable operation and guarantees full motor voltage even when the supply voltage is below nominal.
