DIGITAL THREE PHASE ANGLE

CONTROLLER

SWTA4634

!

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.
