KINETEK KV-50 Elevator InverterThe Kinetek KV-50 Elevator Inverter delivers superior performance for AC gearless installations at speeds to 4.0 meters per second. The inverter is easy to adjust using the on-board keypad and LED display – parameters are set in common elevator industry units.

The inverter supports static auto-tuning, allowing it to calculate motor stator and rotor resistance, stator and rotor inductance, and learn pole/encoder position for ACPM motors — all while the machine remains roped and loaded.

The inverter provides intelligent pre-torque, energizing the motor to prevent roll back and ensure prompt take-offs, regardless of the load in the car — all without requiring a load weigher.

Speed control may be multi-step, providing eight user-adjustable speeds and using the inverter’s internal S-curve generator, continuously variable, analog (0 - 10V), using an S-curve generated by the elevator controller, or serial – which supports stepped or continuously variable speed inputs.

The Kinetek AC Elevator Inverter protects your motor, automatically keeping output voltage stable when input voltage is fluctuating, and protecting against over-current/ voltage, under-voltage, over-temperature, phase failure, over load, and more.
