Product Details

Adopts diode uncontrolled rectification structure, high reliability with low loss.

Inverter adopts an imported IGBT single-phase full bridge inverter structure, which can control the output voltage and current accurately and quickly (in microsecond), then it can achieve real-time arc stabilization faster than any mechanical regulation method.

Adopting a parallel structure for multiple power units of rectifier and inverter, the module power unit can be connected in parallel immensely, it is suitable for the equipment of various capacities. If any power unit fails, it will be disconnected instantly without affecting the operation of other power units.

A module of power unit can stop operation for maintenance online or put in operation online.

Modular power unit system can adapt to the operation of 2, 3 or multiple electrodes furnace, increase or decrease the number of module power units can meet the requirement of various capacity furnace.

Redundant design of multi-module ensures the max reliability of power supply.

Adopting a dry type transformer structure, with strong short-circuit resistance, maintenance free, and no fire hazards.
