DIGITAL THREE PHASE ANGLE
CONTROLLER
SVTA4650
!
Allows to set the voltage applied to different sort of loads with 3 wires, 4 wires or
inside the delta wiring:
! Resistive (Bulbs, UV and IR lamps, ovens, …),
! Inductive (inductors, transformers, …),
! Motor (motorfan speed control (60 to 100% from the nominal speed),
! Rectified (power supplies, …).
!
!
!
Small housing, easy and ready to use.
Large mains frequency and voltage range.
Fully optoisolated full cycle three phase phase angle controller (balanced
currents, less harmonics, …)
!
!
!
!
!
!
Dynamic control voltage range according to the power factor of the load.
Softstart and softstop functions (increase lifetime expectancy of the load).
Adjustable filter regarding fast input voltage changes (ramps).
Motor softstarting functions to control its speed within the stable area.
Input-output transfert characteristic linearization function (resistive load).
Diagnostic features : Status given on LED and AC/DC switches.
