Leybold Turbotronik NT150 360 Turbo Pump Controller, 85572 Leybold TurboTronik NT 150/360 controller

Leybold Turbotronik NT150 360 Turbo Pump Controller, 85572 This Leybold Heraeus TurboTronik NT 150/360 controller  is designed to operate with Leybold Turbo Molecular Pumps TurboVac 150  TurboVac 360

Overview:

The Leybold Turbotronik NT 150/360 VH solid-state frequency converter converts the single-phase A.C. voltage of the mains supply into a three-phase A.C. voltage with variable voltage and frequency.

The frequency converter is an externally controlled three-phase transistor-rectifier consisting mainly of six transistor switches. These transistor switches are controlled so that a three-phase connection is formed at the output R, S, T. The diodes connected in antiparallel to the connected consumer into the intermediate D.C. circuit.

After depressing the "START" button, the voltage Uzk in the D.C. intermediate circuit is controlled according to an IU characteristic. Current I and voltage Uzk are proportional to motor current Im and motor voltage Um. The frequency of the three-phase output voltage is varied from a preset minimum value, as a function of the D.C. intermediate circuit voltage Uzk, up to a preset maximum value.
