Application details

●Product introduction
The main high-frequency transformer with nanocrystalline cores and imported high-power IGBT modules are used as the main power devices. High-quality materials are selected to ensure quality.

Fully digital design, each unit adopts industrial-grade structured modular single-chip microcomputer as the control chip, with perfect protection function. At the same time, it has a MODBUS field bus network and a parallel current sharing field network. Local operation man-machine interface control function, the system supports ammeter and medicine adding control function, soft start and timing function. Using TB rectification method, the benefit is higher. Due to the pressure drop, the system efficiency is higher than Schottky and more energy-saving. 10 process curves can be stored, each of which can be set for 30 stages of working status, and each stage has a soft start time and timing. Function, digital setting of working voltage or current can realize independent voltage stabilization/current stabilization working mode, and the current sharing accuracy of each module is <1%.

●Product specifications: output current 1000A- 50000A, output voltage 0 24V.
