Industrial battery charger

They are equipment built according to EN and I EC specifications, correctly applied in relation to the type of battery, either lead, or sealed lead or nickel-cadmium battery. The general characteristic for the stabilized voltage system, both single-phase and three-phase, is a maximum variation of output current and voltage within 1% of the rated value, with mains variations of 15%, or from 0 to 100% of the load, considering an alternate residue of 1%, thanks to the LC filter at the output, all models are equipped with.

ALS series

It is to be considered as the most complete series, since it provides a stabilized voltage branch for the loads, and a second branch (also stabilized) for the battery with the possibility to be DUAL, therefore, to make them redundant through an automatic «transfer» among themselves in event of failure. In the smaller versions, they may be carried out with self-contained batteries.

BTE & BTM series

They are provided with one single stabilized branch, both single-phase (BTM) and three-phase (BTE), the last one more suitable for higher power.

Available for any kind of battery, Lead vented, sealed Lead Batteries or NiCd vented, or recombination. Loads are connected directly in parallel to the battery, or electronic Chopper regulator, in the event voltage on the load should be maintained within 1% of rated value, or a diode drop voltage regulator if a load voltage variation of 5% can be accepted. For high performance applications, the rectifier and/or the DC/DC converter (diode or chopper) can be provided with dual parallel redundant configuration. Can operate with voltages up to 600V.d.c., being equipped with I/O galvanic insulation of all reference signals, like voltage and current.
