12V40A PWM Charge Mcucontrol LCD display

Prod Model:	SML12-40

Product Description

FEATURE

Advanced MCU control pulse width modulated (PWM) technology, high efficiency operation.
Target for Gel, AGM, Conventional lead-acid (WET) and Calcium Batteries.
Built in regulator to prevent your battery from being overcharged. Overcharging occurs when the charge voltage is unregulated. This can result in premature battery failure.
Come with regulator to prevent your battery from being under charged, in the solar energy field, battery undercharge always occurs, especially on some Conventional lead -acid or Calcium batteries; The unit provides an automatic Equalization feature for deeply drained Conventional lead acid battery or Calcium battery, as well as provides a cycling automatic Equalizing feature every 28 days.
Can be connected to the battery permanently to keep the battery fully charged by using a process called "floating". This means the controller will stop charging when the battery is full and will automatically start charging the battery as required. This process will also reduce water loss and help prevent the battery from 'drying out'.
Protects your battery from discharge at night. Under low light or no light conditions the solar panel voltage could be less than the battery voltage. The unit contains a special circuit which prevents current flowing back from the battery and into the solar panel.
Colored LED to easily indicate the operational status and battery conditions.
Digital LCD to directly display battery voltage, charging current, charging capacity (Amp hour), battery types and faulty codes.
Provides plug-in remote digital display meter (Optional).
Provides external battery temperature sensor (Optional).
Multi charging protections against reverse polarity, short circuit, over temperature, over voltage, etc.
Surface Mount or Flush Panel Mount options.
Conformal-coating circuit boards and plated terminals apply to hostile environments.
