• 两种夜间照明模式，其中一种可编程
• PWM脉冲宽度调制（串接调节方式）
• 内置温度补偿
• 三阶段充电方式：强充-均衡充-浮充
• 可蓄电池容量(SOC)或者蓄电池电压来控制深度放电保护功能
• 固态电路及负载保护
• 极性反接保护
• 全电子保护

SMLNL系列产品是新一代多功能低成本的太阳能充放电控制器。其电子线路配备了性能优良的单片机微处理芯片，具有高效率充电、五个LED全功能显示、蜂鸣器声音预警及可编程的路灯控制模式等功能。

SMLNL系列控制器带有自动温度补偿的三阶段的充电方式（强充电-均衡充电-浮充电），由脉宽调制（PWM)控制充电方式,可应用于给全密封或不密封的铅酸蓄电池充电。

用户可以自己选择，由蓄电池容量（SOC）还是蓄电池电压来控制深度放电保护功能。

五个LED可清晰的显示蓄电池的不同工作及充放电状态。

SMLNL控制器具有一组可编程的路灯控制模式，当黄昏来临，在一定延时后，负载端自动打开。用户可自定义夜间负载打开的时长，设定时长以1小时为单位，最长可达一整夜。

• 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 SMLNL 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.
