With decreasing Current (wa characteristic): 9÷11 h charging time, transformer thermal protection, Modular installation on galvanized steel base (20/10) – (30/10), sheet steel case With modular panels (10/10 - 12/10) - (12/10 – 15/10), epoxy powder coating, ovenbaked, Standard colour: ral 2002 red, option: custom-made colour, logo and silkscreen 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 the final charge at 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).
