DIGITAL THREE PHASE ANGLE
CONTROLLER
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.

Radiated and conducted
disturbances
The conducted or radiated disturbances generated by
solid state relays depend on the wiring and load
configuration.
The test method recommended by the European standards
NFEN55011 and concerning electromagnetic compatibility leading to
results far from reality, we decided to advise our customer
in order to adapt their filtering scheme to their application.
Please refer to the SVTA – SWTA installation
manual.
