Performance Specifications
Operated within 6105A or 6100B Control Loop, Sine or Harmonic Input (all current
ranges)
The current and phase angle accuracies of the 52120A when controlled by a single 610X, apply to the parallel output of
up to three 52120As connected as slaves. See the 610X specifications for interharmonic, fluctuating harmonic, dip and
flicker specifications.
