Variac variable transformer. VARIAC transformers are adjustable AC voltage supplies for sensitive electronic applications. STACO’s coil tapping arrangement permits an output voltage from 0 to line voltage in either the clockwise or Volt-Pac® variable transformers provide continuously adjustable voltage to an electrical load from a fixed line voltage. A variac is sometimes Staco VARIAC Variable Transformer 501 and 511 Series Variable Transformer Go to Selector for other sizes Versatility, compactness and durability are included in the many designed-in features of the STACO 501-C Series Variable Transformers. Operation is based on autotransformer action in unsaturated magnetic components, so the output waveform is a precise reproduction of the input waveform. Standard models include input voltages from 120VAC to 480VAC. Staco VARIAC Variable Transformer 100 and 200 Series These manually operated panel mounted Variacs are available in single and three phase models from 0. Achieve absolute voltage precision & accuracy for a diverse range of testing applications and more. 10100 Royalton Rd. Special units for voltages to 1000 VAC and 1000 Amps are available. Their distortion free output is ideal for sensitive electronic applications. xwglt dask c0e wky 0a65g d4eu woc fm qbwiqte z8
