Intelligent charger maximises battery performance

October 15, 2018 // By Julien Happich
Model 3743 from Norwegian power design expert Mascot AS is a versatile high-quality, high-performance battery charger that uses a 3-stage charging profile with a microcontroller to maximise battery performance for a wide range of battery chemistries, including Lead-Acid and Lithium.

The new charger is also capable of waking up deeply discharged batteries and soft-start charging with low current until voltage is normalized. It is well suited for a wide variety of applications from medical to consumer. The 3743 is medically certified according to EN 60601-1 edition 3.1. It is also UL-approved and meets the latest DoE and CEC efficiency requirements. Five standard versions are initially available for charging Li-Ion batteries from 1 cell (1.5A/4.2V) to 7 cells (0.56A/29.4V) and 12V and 24V lead acid batteries. The 108.5x49x29mm unit has a power rating of 6W (1-cell) to 18W (14-cell charger) and operates from a 90-264Vac input voltage. Alternative chargers that terminate the charge on reaching the battery´s threshold voltage can shorten charging time but always leave some capacity unfilled. The 3-stage charge control first restores the full battery voltage and then applies the saturation charge needed to fill the battery completely. This ensures the longest possible battery run-time.  The 3743 also features a single 3-colour LED indicator light for charge-, error- or standby-status.  Custom units are available on request.
