DSO Line Chokes

Single-Phase Line Chokes DSO 4%

Single-phase line chokes are designed to limit currents, reduce the impact of line disturbances, and suppress feedback in electrical networks. Chokes with a 4% voltage drop are used to protect industrial electrical equipment, converters, drives, power supplies, and other loads sensitive to power quality.
