The PL6850 is designed to provide stable power, on demand up to 120 amps, to a vehicle electrical system to support module reprogramming. It is also designed specifically for fleet service battery charging with a maximum charge rate of 120 amps, to quickly and effectively bring 4- and 8-battery Group 31 packs back to full charge. In power supply mode, the PRO-LOGIX PL6850 provides power to maintain vehicle electrical system voltage at a preset level, increasing its output in response to system load increases to maintain a stable power environment for successful reprogramming. It features a voltage output range of 13.1-14.9V, adjustable in 0.1V increments. allowing the operator to dial the output in exactly as specified by the supplier of the vehicle under service. It features fast load responsiveness for ultra-quick recovery from system demand increases. It also delivers its massive power with minimal voltage ripple (100mV), providing a clean flow of power to the vehicle without risk of programming interference. In charging mode, the PL6850 utilizes advanced microprocessor-controlled logic to precisely deliver a fully automatic charging routine designed to optimally charge and maintain each battery or battery pack serviced. The PL6850 features the ability to properly charge a wide variety of lead acid battery types, including Conventional, AGM, Spiral Wound, Start-Stop, Deep Cycle and Marine lead acid batteries, plus LiFEPO4 Lithium Batteries – enabling beneficial service of virtually any battery type installed in a vehicle. The PL6850 adapts its charging approach based on the needs of each battery or battery pack it services. Such adaptations can include activating a soft start mode on deeply discharged batteries, a battery repair mode on older/distressed batteries and temperature compensation when charging in extreme temperatures. It also incorporates numerous features to make charging safer for the operator and the vehicle/battery being charged, including over-voltage protection, reverse polarity protection, smart clamp technology and battery fault detection. The unit includes a carry handle for easy transport around a shop or in and out of a mobile service vehicle.
