Charge based on time, charging with decreasing current (wa characteristic): 9÷11
H charging time, transformer thermal protection, modular installation on galvanized
Steel base, sheet steel case with modular panels, epoxy powder coating, oven-baked,
Standard colour: ral 2004 orange, option: custom-made color, logo and silk-screen
Printing, mains input and d.C. Output polarized cables, complete with mains and
Battery cables; assembly of plugs and battery connectors on request.
“wa” characteristic (din 41774):
Charge at decreasing current with intervention of adjustable final
Charge from 2.35 to 2.40 v/cell., final charge with timed control 9h /
11h, fixed charging time (equalization charge excluded), equalization
Charge (week-end charge) to be recalled. It will start after 55’ from
Charge end, duration of equalized charging phase: each hour 5’
(repeated for 48 hours), calculation to determine the size of suitable
Battery charge: 16a for every 100 ah of the battery (e.G. 500 ah
Battery: 16ax5 = 80a).

Benefits of chopper technology
Sirius chopper charger is the faster and safer method to recharge
Batteries in 2 hours. Thanks to this battery charger you do not need
Any dedicated battery room any more, you can avoid all the relative
Maintenance problems and the time recovery, and you have less
Costs for maintenance and infrastructures and less battery packs.
You can also recharge batteries having a great capacity in a very
Short time, during the lunch break or when the vehicle is parked
Momentarily; so the batteries do not have to be replaced in order to
Increase the work time.
