Charge Controller with Nightlight Function
 
  • One programmable nightlight function
  • PWM regulation (series type)
  • Integrated temperature compensation
  • Three-state charging method
  • SOC and voltage controlled LVD
  • Solid-state circuit and load protection
  • Reverse polarity protection
  • Fully electronically protected
The OMLNL series is a sophisticated solar charge controller family for low cost applications.
The electronic circuit is equipped with a microcontroller that provides high-efficiency charging technology together with a number of outstanding status display, warning and safety functions. The SMLNL series comes with two nightlight function mode. One of them is programmable that switch on the load output for a adjustable number of hours from dusk.
The nightlight function is overridden by a battery deep discharge protection to avoid excessive discharge and damage of the battery.
The temperature-compensated three-state PWM charging method (boost-equalize-float) is now adjustable to sealed and vented lead-acid batteries.
The low voltage disconnect function can be controlled either by SOC or by voltage.
The battery status, charging status and load status are clearly indicated by 5 LEDs.
