The Servolink 40 Ampere 3 Phase Variac is the largest air cooled model in our three phase range. It works on a 415 V AC, 50/60 Hz three phase supply and gives smooth, stepless output from 0 to 470 V AC. Three copper toroidal coils, one per phase, are connected in star and mounted on a common shaft, so all three phases move together and stay balanced. Choose the motorized open type for panels and automatic voltage control, or the manual enclosed type for a ready-to-use bench unit with knob control. Air cooled, for indoor use.

Typical applications: industrial test benches, motor testing, process heating and three phase voltage correction equipment.

Construction: 3 toroidal coils (one per phase), star connected, mechanically ganged on a common shaft
Winding: 100% Copper
Control: Geared motor drive (Motorized), Knob with dial (Enclosed)
Brush: Carbon brush (one per phase)
Frequency: 50/60 Hz
Dielectric Strength: 2.5 kV AC for 1 minute (winding to body)
Conformity Standard: IS 5142 : 1969
Mandatory Spares: Spare carbon brush set (3 nos.)
