Product Description

TENYES 1200KW High frequency pipe welding machine Ordinary three-phase AC power (line voltage 380V, frequency 50HZ) is reduced by a transformer (line voltage 200V, frequency 50HZ), enters the rectifier cabinet, undergoes rectification, voltage regulation, and filtering, and becomes continuously adjustable DC power from 0 to 240V; Entering the inverter bridge again (using high-power transistor MOSFET), it becomes high-frequency current, which can be supplied to the load slot for induction heating. The inverter slot power unit adopts a modular structure, and each pair of power units can output a power of over 50KW. The number of power units used varies depending on the power of the equipment, and the basic structure of the equipment is the same regardless of its size. The slot is a series parallel hybrid resonant form, without high voltage and output transformer. The number of power units used in this device is sixteen pairs.
