Advantages of Green Power power supply
1) High Reliability
A loss of power results in tremendous loss in production, anodizing industry do not allow any compromise on reliability of the power supply. Protection measures (e.g high voltage absorbing circuit) adopted to protect components in case of power shortage. Fully digital control system, anti-jamming, strong ability to resist strong magnetic field, high reliability. Using high precision current sensor as feedback control to improve the reliability of system operation Using optical fiber transmission thyristor trigger pulse signal, suppress magnetic-field interference and improve the control system of electromagnetic compatibility to ensure the stable operation of the system. This set of power system components are all use international famous brands with high quality, make strict inspection to the device, and fully guarantee the reliability of the equipment.
2) Power Saving
Save energy and increase revenue, electrical energy is a costly and valuable resource and one of the major cost factors. Therefore Green Power has spent years tuning its systems to provide utilities with the highest efficiency and the lowest electrical losses. Our solution is based on design criteria that all result in energy savings: − Optimized transformer and power supply design − Customized selection of semiconductor and power fuse − Shortest possible transformer-power supply connection − Custom design to keep current density in power conductors and DC isolators low
3)High Output Stability, High Control Accuracy
High stability and high accuracy(default <1%) ensure high quality anodizing products. USA TI company's DSP chip, programmable full digital control system, trigger pulse features are consistent. Using the military level pulse transformer, Pulse asymmetry degree ≤0.1 °, Pulse leading-edge steepness ≤1uS. Controller is equipped with communication interface, can be communicate with PLC directly,ensure system response time and system processing precision.
4)Low Output Ripple
Low ripple(default <5%) . The optimal transformer adopts 6/12/18/24/… pulse rectification, through thyristor control angle get lowe ripple withfully conducted condition.
5) High Power Factor
High power factor reduce reactive power, transformer's capacity and line current. Thyristor control angle are controlled between 12-25 degrees during system operation, when thyristor control angle is
less than 12 degree, the system send tap changer upshift signal; when thyristor control angle is greater than 25 degree, send downshift signal. The signal of upshift and downshift are automatically controlled by power supply or switched manually, to improve power factor and reduce harmonic content. Long lifespan More than 25 years lifespan, reduce investment. Reasonable design, high quality parts and materials, excellent craftwork, ensure the high realiability of the power supply.
6) Friendly HMI
Intelligent and convenient operation and monitor. Touch screen control, operation and display. Convenient forming industrial network, analog signal, RS485, Profibus communication, convenient remote control
