2. Technical parameters

IF power supply	Working form: Inverter parallel SCR 6-pulse power supply
	Rectification form: 3-phase 6-pulse
	Output power: 100KW
	Power efficiency ≥98%
	Start mode: buffer variable frequency start
	Start-up rate: 100% (including heavy load)
	Rated frequency: 500HZ-1000HZ
	AC voltage: 400v
	DC voltage: 500V
	Intermediate frequency voltage: 750v
	Maximum DC current: 200A
	AC current: 160A
	Input frequency: 50Hz
	Dimensions: 1300mm×800mm×2000mm (length×width×height)
	Weight: about 1000KG
sensor	Minimum power factor: 0.90. There is no power factor meter on the detection standard IF cabinet, and the DC voltage reaches the maximum 500v power factor that is above 0.9. Because the intermediate frequency power supply purchased by Party A is regulated by voltage and power, power reduction is accomplished by reducing the DC voltage. Reduce the power, the power factor should also be reduced.
	Working method: one electric and two furnaces
	Working temperature: 2300℃, quick connector for water inlet and outlet
	Induction coil specification: outer diameter 980mm height: 1020mm, copper tube: loose guide reasonable calculation of design coil number and specifications
	Weight: about 200KG induction coil base welded with 120mm channel steel, convenient for forklift use
