SVTA4694
! 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.
