Ptek_Nre3

Ptek nre3 three phase is designed to recharge medium - large capacity traction
And start lead-acid batteries, developed using our forty-year experience in the field
Of battery chargers and multi-years application of microprocessor control systems
D electronic circuit conforming to the
Directive on electromagnetic compatibility and ce marking, automatic disconnection
Of battery charger due to battery disconnection, equalization 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 color:
Ral 5003 blue, 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). 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).
