Decades passing by, Guangdong Sikes Electric Co.,Ltd has successfully designed and produced a series of mature solutions according to the application of frequency inverter and servo drive. DC Internal Choke is one of these related solutions,dedicated for inverter.Combined with frameless process and Coiled with foil winding,Compact structure.

Characteristics：
1. High Temperature Resistant : The inside insulation material is combined with frameless process, the choke’s temperature heat-resisting ability is strong, and the class F or H is optional.
2. Noise Decrease : Choke air gap adopts argon arc welding process, which has low noise, small magnetic flux leakage and stable inductance.
3. Electric Magnetic Resistance: Coiled with foil winding process, choke has strong resistance of electric magnetic force and good presentation quality
4. Small volume: Core with grain-oriented cold-rolled silicon steel sheets, making chokes have high reliability,small size,light weight and low cost.

Nominal Voltage Range: DC 500V-1200V
Nominal Current Range: 3-2000A
