Low Voltage Switchgear GZDW Series DC Power Supply System Panel Cabinet
Product Description:
GZDW series DC power supply system is composed of intelligent high frequency switching power supply module, monitoring unit, voltage lowering module, switch quantity module, AC and DC detection module, insulation detection module, battery inspection module, battery and feed back module. It has many advantages, such as high precision of steady voltage and steady current, fast response speed, low noise, high degree of intelligence, convenient operation and maintenance, high reliability and so on. It can communicate with the upper computer and realize the function of "four remote" very conveniently. Is a generation of ideal DC power supply equipment. It is suitable for power plants, hydropower stations and substations in power system, as the DC power supply for control, signal number, protection, telecontrol communication and lighting. It is widely used in electric power, petrochemical, mineral spring mountain, electrified railway, metallurgy, etc. Mechanical and high-rise buildings.
Product Feature:
●The charging module (rectifier module) adopts advanced phase-shifting resonant high-frequency soft switching technology, which has high efficiency, good reliability, good electrical performance and electromagnetic compatibility.
●Adopting the stepless current limiting mode, the battery charging current limit accuracy is high;
●Can live hot plug and pull, on-line maintenance is convenient, fast;
