High-Frequency Switching Power Supply (0-500A) - Precision GGD Series from China Suppliers and Factory
Product Feature
GGD high-frequency switching power supply uses IGBT as the main power switching element, imported drive, high-performance fast recovery tube as the rectifier device, and non-inductive capacitor. It is a new power supply with high efficiency, energy saving, reliable performance, compact structure and simple operation. It is widely used in electrochemical fields such as surface treatment and electrolysis.
The power factor of high frequency switching power supply is very high that because of the inverter technology, and it can reach above 0.9 without reactive power compensation. The harmonic content is also small. The on-state voltage drop is effectively reduced, the efficiency of the machine is improved and the energy is saved by using the fast recovery tube rectification method. The characteristics of high efficiency and high power factor make it save electricity by 20% compared with ordinary SCR rectifier and 30% compared with silicon rectifier.
The output voltage and current can be adjusted continuously, and the constant voltage and constant current working mode can be selected, which greatly improves the flexibility of customers. It also has the functions of remote operation and communication with upper computer.
The power supply has the characteristics of small volume, light weight, high efficiency, low ripple and high control accuracy.
Provide RS485 communication technology.
The switching power supply is designed for electromagnetic compatibility, which does not affect the normal operation of other equipment on site.
Choose high-quality power components with high reliability: Rectifier is a productive equipment, which usually needs 24-hour continuous operation, and the quality of power components directly affects the reliability of the whole machine. All power components of this device adopt high-quality components of well-known companies at home and abroad.
