Atkinson PVLC-40MD Lighting Charge Controller

Atkinson Electronics, Lighting Charge Controller with Motion Detector, 40A, 12-24V, PVLC-40MD

The PVLC-40MD Charge controller monitors both the battery and PV panel voltage, if PV panels have sufficient voltage for charge, and if the battery bank requires charging. When charging the PVLC-40MD cycles the charge relay every 4 minutes to re-verify open circuit PV charge voltage to avoid discharging the batteries through the PV panels when low light conditions occur. The charge re-connection time is varied by the micro-processor to optimally reduce the charge rate for nearly or fully charged batteries. The PVLC-40MD internal temperature compensation adjusts the charge threshold voltages for optimum charge of the battery bank based on temperatures between 0°C to 45°C. For a complete chart PVLC-40MD Temperature Thresholds section next page.

The PVLC-40MD Lighting controller monitors the motion sensor, PV panel voltage and battery voltage and initiates the “light-on” cycle when either the motion sensor has been activated or a dusk voltage threshold has been reached for dusk to dawn operation. The relay remains energized until either the time selection is reached, the PV voltage indicates dawn, or the battery voltage drops below 11.3V DC for 5 continuous minutes. If the lighting relay drops out on low battery voltage or is below 12V at dusk, it will not re-energize until the battery has been charged up to 12.4V DC.

The PVLC-40MD has ten lighting settings (See PVLC-40MD switch - lighting adjustments for timing selections). There is OFF, 4 night only settings, Dusk to Dawn setting, and 4 anytime settings. Selecting (5) “Dusk to Dawn” on the timing switch causes the lights to turn on at dusk and remain on until dawn (subject to the low battery voltage cutout). The PVLC-40MD also can have an optional 5 or 10 minute max lighting time within a 30 minute period. By clipping either the White (5 min) or Gray (10min) jumpers this activates the max lighting routine.
