Application Scope


Sapphire single-phase power frequency furnace heating power supply is mainly for the gem furnace which needs of single-phase AC power supply. The product can provide power output with high precision and reliability for the sapphire furnace production process, so as to ensure temperature stability of the sapphire crystal process.


Product Principle

It adopts transformers primary lateral pressure regulating and secondary lateral voltage reducing. Use transformer primary side and secondary side voltage regulator voltage output. With double closed loop control in the whole process, the output voltage is of high precision and high reliability.

Technical Features:

1. Flexible operation and convenient maintenance: It installs LCD (Liquid Crystal Display) monitor panel and displays operation parameters in real time. The control parameters can be modified online and fault information can be automatically recorded, etc.

2. High control accuracy and good stability: It adopts phase-locked loop synchronous circuit and 16-bit digital trigger. It does voltage and current sampling by True-RMS calculation chip. It is designed of multiple software protection function for overvoltage, overcurrent, overheating, feedback disconnection and lack of phase alarm etc. The power devices and circuit breaker etc. adopt international and domestic famous brands.

3. Advanced processing technology of transformer: Transformer adopts high-low pressure complete foil coil winding, step laminated and damping measures. It is with merits of low noise and loss, light weight with small volume, and saving installation space. It has strong heat dissipation ability to achieve 20% overload running stably under the condition of forced air cooling.

4. Digital communication control:It control the output power of power supply cabinet through the MODBUS communication mode and read the real value of output voltage, current and fault type, etc.
