AC converter (AC source) » EAC-K-1 & EAC-K-3

EAC-K systems are controllable AC sources where the output voltage and the output frequency can be adjusted to supply different AC consumers with different voltages and frequencies. E.g. in the test area, test laboratory or in development. The built-in LCD display shows the frequency, output voltage and output current. Voltage control e.g. 100-260V, 40-270V Frequency control e.g. 45-65Hz, 360-800Hz Systems available 1-phase or 3-phase.

Technical data:

  • Outputs from 1 kVA to 30 kVA, 1- or 3-phase or switchable from 1-phase to 3-phase operation
  • AC input 110V to 690V
  • AC input 45Hz to 400Hz
  • AC output 45Hz to 800Hz
  • Setting range e.g. 45Hz-65Hz, 50V-260V
  • 1-Ph up to 10kVA
  • 3-Ph up to 30kVA
