EP12/24 10H-1-2L adopts MCU and special software achieving,intelligent control with five operating modes, featuring smallvolume and high stability. This product can be widely used in solarDC road lamp, solar yard lamp, lawn lamp, solar lightbox andbillbord etc.
Performance:
1. 12/24V automatic identification.
2. Extreme accuracy in controlling voltage. Adopting 32-bitprocessor.
3. Automatic temperature compensation function. Hot-awappable toaid temperature transducer.
4. PWM charging modes with higher efficiency.
5. All-round protection function against overcharging,overdischarging, wrong connection, opencircuit, controller andbatteries in over temperture, overvoltage, overload, shortcircuit,reverse charging in night etc.
6. Applying nixie tube work modes in overvoltage and overloadinstruction. A key operation for convinience and intuition.
7. Intelligent 3-section charging control, to assure batteries offullness, system will switch to relvant modes according to thewoking status.
8. Adopting low-loss, long-life MOSFET tube as main switchingdevices in controller.
9. Auto-saving function for working mode setting. System andimportant parameters saved inner chip without losing power.Relevant parameters would be read while booting.System is morereliable to work.
10. Various operating modes for choice, optic control, opticcontrol time control, common mode, manual mode and advancedmode.
