Product Overview
TDGC2 Single Phase Voltage Regulator is an adjustable autotransformer structure; The coil is wound evenly around the ring-shaped iron core. The electric brush acted by the spring pressure, dovetails closely with the coil's polished surface to turn the pivot to drive the brush bracket so that the brush can slide along the coil's surface to change the brush's contact position, namely, change the turn ratio of primary and secondary coil , for the purpose of smooth and stepless regulation of output voltage within the regulation range . Contact Voltage Regulator was featured by its undistorted waveform, compactness, light weight, high efficiency, easy use, reliable operation and so on. 

Normal working conditions and installation conditions
The altitude does not exceed 1000m.
Single Phase Contact Voltage Regulator Ambient temperature: the highest temperature is +40°C, the highest monthly average temperature is +30°C, the highest annual average temperature is +20°C, the lowest temperature is -5°C
The average relative humidity in the wettest months is less than 90%, while the average Min temperature in the month is 25°C.
Waveform of the power supply voltage: approximates the sine wave.
Single Phase Contact Voltage Regulator Installation environment: Cannot be used in parallel; Indoor use; The installation site should not have gas, steam, dust, grime, chemical deposits and other explosive and aggressive media that seriously affect the insulation of the Voltage Regulator; the installation site should be no severe vibration and bumps.
Any special use conditions other than normal use conditions that need to meet the above requirements shall be stated in the inquiry and order.
