VKCS series of dynamic non-contact switching regulator (sub-fill type) | SCR

I. Overview VKCS series reactive compensation move up regulator is a shunt capacitor capable of fast power electronic switching type power device module, with unlimited number of switch operating life, while ensuring that the reaction time can quickly follow load changes. Electrical structure is dominated by the power and even the anti-thyristor modules, isolation circuit, trigger circuit, synchronous circuit protection circuit and driver circuit, and with a control switch is turned on or off terminals, logic control voltage OV (off), 12V (conducting). This switch is a fast response, no switching inrush current, work without noise, stable and reliable, lack of protection, simple installation and easy maintenance. It is ideally suited for dynamic reactive power compensation device by switching capacitor banks. Second, the main technical parameters Rated voltage: 380V (220V) Rated frequency: 50Hz control capacity: 380V level (total complement): 1Kvar ~ 80Kvar 220V level (sub-fill): 1Kvar ~ 10Kvar control voltage: 12V three soil conditions a.. Ambient air temperature: -25 ℃ ~ + 50 ℃, and 24h average temperature does not exceed + 35 ℃; b temperature of + 25 ℃, relative humidity of short-term up 100%; c altitude does not exceed 1000m.. ; d installation site air clean, non-explosive and flammable dangerous goods; No sufficient to damage the insulation and corrosion of metals in the gas; non-conductive dust; no rain and snow and severe mold presence;. e installation site no overrun harmonic weight The presence of the occasion, the voltage distortion rate environment does not exceed 5%, otherwise the capacitors in series between the regulator must VLBD series filter chokes to suppress higher harmonics.
