Special mains for rare earth smelting

Product Introduction

●    Rare earth electrolytic power supply and rare earth smelting power supply are specially used for heating and electrolytic smelting of rare metals and precious metals.

●    This power supply is specially used for electrolysis of rare metals and rare earths, heating of precious metals, and electrolytic smelting.

●    Adopt N+1 redundant power supply system design, modular power supply, expanded capacity, enhanced reliability and energy saving.

Product Features

●    Power supply design:  N+1 mode is adopted. Under normal circumstances, all modules are involved in the work. If the equipment fails, the power supply will not stop. The system will automatically exit the faulty unit to reduce the current. The equipment keeps running without affecting production.

●    Digital design:  single-chip microcomputer, DSP as CPU, more precise control. Support bus control, can form a central control power supply system, easy to manage and improve efficiency.

●    Digital control:  each module unit is controlled by a microprocessor, and mainly uses software programs to realize automatic current sharing and other control schemes. The control is flexible, accurate, dynamic response is fast, the number of components used is small, and the reliability is high.

●    Low loss, anti-interference:  the current advanced adaptive resonant full-bridge PWM control IC is adopted, with adaptive zero voltage delay control function, which reduces the loss of IGBT by 40%, and also adopts a new rectification mode and rectification device, the device voltage drop is 0.1V-0.2V, and the rectification efficiency is greatly improved.

●    Small size, high precision:  high-power and high-voltage IGBT with ultra-high frequency and low saturation voltage drop is selected to reduce the size of the core material; at the same time, the low saturation voltage drop characteristic also reduces the IGBT loss. The main high-frequency transformer adopts nano-based materials, and the imported high-power insulated gate bipolar transistor "IGBT" module is used as the main power device. High-quality materials are selected to ensure quality.
