LED Digital Display PSE 20A PWM Charge Controller
LED Digital Display PSE 20A PWM Charge Controller
Function:
1. 12V/24V Automatic identification by system
2. LED digital display and one-key operation, easy to use
3. The improved 3-section computing method can weekly give the battery a balanced charging. It can stop the battery from being unbalancing and vulcanizing and let the battery been used for more time.
4. the controller is equipped with the serial PWM charging main circuit with additional 3%~6% efficiency than the non-PWM circuit which can work for more time and increase the using period of the system.
5. Controller has three load work ways and can be easily used in varies streetlights and monitors.
6.Visualized LED display which can let the users get to know the conditions of solar power and storage battery.
7. Overcharge, over discharge and overload protection; Electronic short circuit protection; Reverse connect preventing protection.
8. Lightning prevention.
