System overviewThe charging module adopts th series intelligent high frequency switching power supply independently developed by our company. This series of power supply is designed for power system and has the function of "four remote". The power supply adopts the world leading "resonant voltage type double loop controlled resonant switching power supply technology", which has the advantages of small volume, light weight, high efficiency (over 95%), high reliability. The products include three series of 220V, 110V and 48V, dozens of varieties, equipped with standard RS-485 interface, easy to connect with automation system, suitable for substations and switching stations with different voltage levels from 500kV to 10kV, power plants with 15mw-60mw power generating units, and national key projects such as subway, oil field, chemical industry, metallurgy, etc. The charging process is in line with the charge curve requirements of lead-acid battery and nickel cadmium battery. The system realizes intelligent charging management for the battery and has the function of temperature compensation. The monitoring system is equipped with standard rs-232/485 interface, which provides a variety of communication protocols, convenient access to automation system, open protocol, convenient networking, easy realization of "four remote" and unattended System parameter descriptionAC input voltage: 220V ± 15% Grid frequency: 50 Hz ± 10% Output current class: 30A ~ 300A Applicable battery capacity: 10Ah ~ 2000AH Rated output voltage: 48V Output voltage range: 40-57VDC Output current limiting: rated current × (10% ~ 105%) Dynamic response: when the load changes from 20% to 80%, the recovery time is less than or equal to 200 μ s, and the overshoot is less than or equal to ± 5% Efficiency: ≥ 95% (single module) Insulation resistance: ≥ 20m Ω Insulation strength: apply 2.5kvac to output to ground, input to ground and input to output, no flashover and flashover for 1min.
