DC600V Air-conditioner Inverter Power Supply
It provides power supply forthree-phase electrical equipments such as air-conditioners in DC600Vair-conditioned passenger train, and for other three-phase equipments requiringisolated power supply by isolation transformers.
Charging Case
8KW charger is used for emergency battery and to provide DC power supplyfor DC electrical equipments, such as on-board lighting, control cabinet,sliding plug door and toilet waste water collection system etc.
3.5KVA single-phase inverter is used to provide single-phase AC powersupply for emergency ventilation equipments, vedio systems, conveniencereceptacles etc.
Systemfeatures
Digital Technology
Industrial advancedDSP master chip is employed to improve anti-interference capacity and responsespeed of the product, effectively reducing different faults caused by excessivephase state;
CANbus communication technology is employed in the system to improve communicationspeed and quality;
Stepless intelligentspeed fan, with device cooling redundancy, improves environmental adaptabilityof the product, and extends the product life;
Strict Selection
Domestic andinternational famous brands are employed for all the components in the productto ensure the quality stability of batch supply;
Military grade componentsscreening process is employed for the key components, combined with theselecting standard of high-temp long-life capacitors, ensuring a life of morethan 20 years for veneer.
Multiple Protections
The products are allwater-proof, anti-vibration and dust-proof, and an anti flying-stone structureis adopted for the train operating, which can endure harsh externalenvironments;
Corepower device IGBT is equipped with protections of overvoltage, overcurrent,overheating and anti-piercing;
The panels employ water-proofdesign, with Skull protection designfor the main control panel, achieving comprehensive protection of core control;
Matureelectromagnetic compatible design is employed to prevent electromagneticinterferences and reduce electromagnetic pollutions.
Quick Overhaul
Self-adapting modulardesign is employed for inverter power supply, supporting off-line overhaul andrepair with easy module handling;
Component-typemounting is employed for wearing parts, and anti fault plugging design forinterfaces, to improve speed of overhaul and eliminate incorrect operations.
Environmental Protection
Overallefficient is more than 2% higher than that of the industrial standards, whichensures efficient utilization of power and controls energy consumption ofequipments;
Harmonic content is 1% lower thatof the industrial standards, improving load electricity cleanliness.
