Inverters testing choke SKS-FZ-0300-AB/4-69

magneticwire-woundferrite

Load reactor is designed to test frequency inverter. Features of Three-phase load reactor: The windings adopt foil winding structure, which has small DC resistance, Strong at short circuit withstand capability and short time overload capability; The use of composite insulation materials with an insulation level of F or H allows the product to maintain reliable performance under severe working conditions; Reactor has low magnetic flux density, good linearity, strong overload capability, and low noise; The iron core adopts low-loss cold-rolled oriented silicon steel, the reactor has low loss, high efficiency and low temperature rise. Parameters of Load reactor： Rated power:0.55kvar-1000kvar Voltage range:380-460V Inductance value:0.49-20.0mH Working mode: short-term work or long-term work( for two hours or more at rated current) Inductance value error: ±10%, short circuit UVW,RST input current. Phase type: three phase Frequency: 50-60Hz Cooling mode: AN/AF Insulation Class: F/H Altitude: 1000m, operating frequency value decreased correspondingly when above 1000m. Temperature range:-25℃~45℃. Storage temp: -40℃~70℃ Operating humidity: relative 10%-90% Anti-pollution: 3 class Anti-salt-mist degree: salinity 0.1mg/m³ Standard: IEC289:1987 choke, GB10229-88 choke(eqv IEC289:1987),JB9644-1999 choke for electrical transmission of semiconductor
