Jetline arc voltage control systems assure consistent, high quality welds for either AC or DC applications by controlling arc gap/arc distance, the distance between the tungsten and the work piece.
Jetline arc length control technology includes a unique sensing system constantly monitoring welding arc voltage. Variations are instantly sensed and corrected to maintain the arc length at the predefined distance within an accuracy of ±0.1 volt.
The voltage regulators are the ICs that always watch over the output voltage and keep the voltage steady at constant value. There are positive voltage regulators, negative voltage regulators and voltage regulators in which voltage detect function is built-in.
Transformers with motor-driven tap changers can be controlled with automatic voltage regulators.
Actuation of the motor drive leads to a voltage change by one tap. If the difference between actual voltage and set-point exceeds a certain limit, a regulation comand ("up", "down") is initiated.
SPRECON-E-C-AVR can be adapted to customer-specific requirements to the greatest possible extent. Moreover, several units can be operated in parallel mode, which is based on the master/follower principle. Thereby, the circulating reactive current is monitored.
