Auto Transformer

(Variac Slidac Stelltransformator)

.Produced by YuHseng Electric Co., Ltd

An auto-transformer is an electrical transformer with only one winding. The "auto" (Greek for "self") prefix refers to the single coil acting on itself and not to any kind of automatic mechanism.  Variable auto-transformer means an auto-transformer can be adjusted output voltage range. Adjustable auto-transformer in general be used in voltage control applications including AVR (adjustable voltage regulator), Voltage Regulator, Motor manipulator, Torque motor, Motor control, Apparatus probe, Product test, Lab test facility, High volt regulated motor manipulator, and so on.

Description

 

  • The terrific design and assembling convert input voltage to output without waveform distortion.
  • Multi-model lineup meets the varied industry requirements.
  • Handy and compact design for easy installation.
  • All products are examined by complicate QC test.

 

Features

 

  • Adjusts AC output voltage continuously and efficient heat dissipation.
  • High quality brush provides long life time for frequent adjustment.
  • Minimize the spark and contact resistance.
  • The outstanding synthetic resin of knob and shaft perform well insulation.
  • Each coil has pass prevention test to prevent damage due to high temperature.
  • Customize is input and output available

 

Applications

Adjustable autotransformer in general be used in voltage control applications including AVR (adjustable voltage regulator), Voltage Regulator, Motor manipulator, Torque motor, Motor control, Apparatus probe, Product test, Lab test facility, High volt regulated motor manipulator, and so on.
