How it works, charging limits and levels, and general device functionality
Operating principles
A rectifier converts alternating current (AC) to direct current (DC). Its normal function is to charge the battery and keep it in top condition while providing DC power to other loads. Therefore, the device must be operated taking into account the type of battery (Pb or NiCd) it is powered by.
It works automatically and continuously evaluates the state and temperature of the battery and other system parameters to guarantee stable voltage and low ripple.
It can contain load disconnect operations for ending autonomy, thermomagnetic distribution, fault location, grid analyzers, etc.
Battery Charge Limits and Levels
For sealed lead batteries, only two current levels (float and charge) are used, while open lead and nickel-cadmium batteries use three current levels: float, fast charge, and deep charge.
Float: Used to maintain the battery when charged according to temperature.
Fast charging: done in the shortest possible time to restore the capacity the battery lost during discharge; at a limited current and final voltage for stable charging.
Deep charge or deformation: Periodic manual operation to equalize battery elements; at limited current and final voltage for stable charge. Done in a vacuum.
From float charging to fast charging and vice versa:
Auto: Adjustable when the current exceeding the specified value is suddenly absorbed. Conversely, after the sink current drops.
Manual (optional): Press the local/remote button.
