Mains Choke N Cnw 903

Three-phase mains choke 4%

DESCRIPTION

Power Noise Reduction – save up to 20% on energy costs. A mains choker relieved the supply network by compensating the harmonics reactive power. The harmonics and commutation notches are reduced strongly. By using a mains choke the inverter electronics and DC capacitors will be protected.

Starting currents and current peaks are reduced up to 60%. Mains chokes help to comply with international power quality standards IEEE 519 or EN 61000-3-2.

ADVANTAGES

• Compact design
• Extended lifetime of electrical consumers
• Low-temperature rise
• Attenuation of current spikes up to 60%
• Reduction of input current up to 20%
• Low noise
• Production according to UL insulation system E251513 is possible

TYPICAL APPLICATIONS

Drive systems for motor drives, Mechanical engineering, Elevators/escalators, Pipes, Conveyor technology, Ventilation and air conditioning, Robotics, Automation technology, Power supplies, Wind turbines
