Continuous regulation self-transformers ARC: Leaders in continuous regulation of alternating voltage Salicru offers the ARC as a cheaper, safe, stronger means of having regulable alternating voltage with high precision, continuously and without interruptions. Based on ARC (Continuous Regulation Self-transformer) blocks, toroidal, they may be supplied by single phase or three- phase, and motorised, for control from distance by means of an inertia-free servomotor with double direction turning and instant braking. They may also be made in a frame surround or be portable, and have measuring instruments such as voltmeters and/or ammeters. Applications: Precision regulation in industrial processes It is in the industrial processes where the most of the ARC applications are found. From lighting technique applications, galvanotechnics, galvanoplastia, electrolysis, temperature regulation in electric ovens, speed regulation, electrical tests and controls and voltage regulation, to forming part of practice benches in schools and polytechnic universities; all require precision variation of the output alternating voltage offered by the AR

REF. JM623G01 CODE 401AB000400 ED. JULY 2020 - TRANSFORMERS AND AUTOTRANSFORMERS Performances ∙ Broad margin input and output voltages, single phase and threephase. ∙ Linear output voltage, with capacity to take values such as the number of coils in the core of the self-transformers. ∙ Manual or powered regulation. ∙ Frame or case format (with /without meters). Range MODEL Technical specifications Maximum current Imax that can be supplied for the nominal mains voltage. Admissible momentary overloads Ks depending on their duration. If they exceed 40ºC, the nominal current In will be affected by...
