The VarPlus throttle coils are designed to protect the capacitor by preventing the amplification of the harmonics present in the system. Capacitors and reactors are configured in the series oscillating circuit. Adjusted so that the serial resonance frequency is below the lowest harmonic frequency in the system. This choke is designed for an output power of 12.5 kVar with a tuning sequence of 4,2/210 Hz at 400V AC and 50 Hz. Relative impedance, 5.7%. This component complies with the IEC 60068 standards. This component requires forced convection, a fan must be added. The dimensions of the housing are 220 mm in height, 240 mm in width and 160 mm in depth. For a product weight of 12.5 kg.This text is machine translated.
