Teseq’s VAR 3005A-S16 is a single phase motor variac that allows to steplessly adjust the EUT supply voltage from 0V to 260 V when supplied by a 230 V mains supply voltage. By means of the VAR 3005A-S16 tests as required in the standard IEC / EN 61000-4-11 (voltage dips and short interruptions as well as the optional voltage variation) can be performed adjusting the voltage to any voltage level. Apart from this the motor variac is used for power-frequency magnetic field tests as per IEC / EN 61000-4-8.
