2. Our advantage
Good performance for | Detailed information |
Energy saving | Energy saving 15-20%, efficiency higher than 88%, cheaper by 20 percent in actual power consumption due to low conversion loss. Power saved is power earned |
Even plating layer | low ripple DC continuous waveform or high frequency pulse output optional, high accuracy current supplied to ensure even plating layer |
Small size | IGBT Power supplies occupy less space occupied by traditional type. A 2000 Amp 12 Volt unit occupies 500 mm x 650 mm floor space. Height 650mm. A traditional unit could occupy 1,5 x 1.5 metres sq . Height. 1.50 m |
Light Weight | IGBT power supplies weigh less than Traditional type. (Example. 2000 Amps 12 Volts weighs 70 Kilos. Compared to 800 kilos in Traditional mode) |
High reliability | IGBT power supplies by Beijing Chunshu work at FULL rated value 24 hours 365 days without failure. PROVEN High reliability. Cabinets fully sealed to prevent acidic alkaline air and dust and moisture from entering. Redundancy technology for non-stop operation |
Vey long life possible | Good quality components used reasonable design to ensure long lifespan(15-20 years) |
Touch screen | User friendly controls and easy to read digital meters. Touch screen option for more convenience |
Easy to repair and maintain | touch screen supply fault type alarm, self diagnosis. Modular structure for easy replacement |
