The SVTA models are three-phase proportional controllers that can control any type of load (except capacitive loads), 3 or 4-wire (neutral), delta or star assembly:

• Resistive loads for temperature control (infrared lamps, furnaces, heating elements, etc.)
• Resistive loads for lighting control (filament and halogen lamps, UV, stage lighting, etc.)
• Loads including a transformer, an induction coil or a rectifier for voltage control (rectified power supplies, high voltage generators, etc.)
• Motor loads for speed control (depending on the type of motor and machine).
• Three-phase phase angle controllers with six proportional control thyristors (balanced currents, less harmonics, etc.)

→ Start and stop ramps (increases the unit’s service life)

→ Diagnostic functions

→ Compact package
