3-step Lead-Acid Battery Chargers: 6V / 12V / 24V, 40W

Description

This series of plug-top chargers delivers the power and performance one would expect only of devices of much bigger size. These very efficient chargers feature obvious advantages over conventional types: Very lightweight and compact Universal input ******0V Selector switch to choose from 2 different charge voltages Extreme mains fluctuations do not affect charge voltage Despite its small size, the *-stage characteristic of this charger will still deliver the energy necessary to fully re-charge and maintain moderately sized batteries, within a reasonably short period of time. The charger outputs a constant charge current until the charge voltage has climbed to *4.7V (7.3V / *9.4V). Starting from there, the Charge voltage is being held constant for about **0 minutes, allowing the charge current to gradually decay to a small "trickle" current, towards the end of this timed period. at this time the battery is full. At this point the charge voltage drops to *3.8V (6.9V /*7.6V), float-charging the battery with a small trickle current to compensate for its self discharge, a condition inherent to all batteries. The 3 charge phases are being indicated by distinctly coloured LEDs: - Red for "Boost Phase" (Constant Current) - Amber for "Timer Phase" - Green for "Float Phase"
