DIGITAL THREE PHASE ANGLE
CONTROLLER
!
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.
