Ptek TD3 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
which constantly monitors the basic parameters to ensure a correct operation and
therefore safeguard the battery’s life.
400V or 230V three-phase supply (possibility to request voltages different from the
standard ones), adjustable to ± 5% or ± 10%, microprocessor-controlled programming
and measuring via digital gearcase, 24V- 50Hz supply, Such microprocessor control
is designed to optimize the charging cycles for any type of battery, three mains
input fuses, 24V coil three-pole contactor, auxiliary transformer suitable for the
supply voltage, D.C. fuse on rectifier output, delta-star stray flux three-phase
power transformer, TENVEX copper windings with double enamel insulation; class
H; impregnated in autoclave with ecological epoxy resins, with thermocouples for
disconnection due to maximum temperature, three-phase rectifier bridge with silicon
diodes, natural cooling, with snubber protection, mains input and d.c. output polarized
cables, modular installation on galvanized steel base (Type A: 20/10, Type B :30/10),
sheet steel case with modular panels so as to assure maximum accessibility in case
of service (type A : 10/10 - 12/10, type B : 12/10 – 15/10), epoxy powder coating,
oven-baked, standard color: RAL 2002 Red, lab-tested electronic circuit conforming
to the directive on electromagnetic compatibility and CE marking, equalization charge
timed, automatic Start, automatic disconnection of battery charger due to battery
disconnection, smart charging system according to the discharge level of the battery,
short check of functions and times, option: custom-made colour and custom-made
logo and silk-screen printing, final acceptance test conforming to safety regulations,
charging with decreasing current (Wa characteristic): 9÷11 h charging time, charging
with decreasing current (Wo - Wa characteristic): 7÷8 h charging time, complete
with mains and battery cables; assembly of plugs and battery connectors on request.
WO-WA - carica a corrente decrescente con
intervento della carica finale a 2,42 V/el, carica
finale controllata a tempo, tempo di carica previsto
(carica di equalizzazione esclusa) 7h / 8h, carica
equalizzazione (carica week end) a richiamo inizio
dopo 55’ dalla fine carica, durata della fase di carica
equalizzata ogni ora 5’ (ripetuta per 48 ore), calcolo
per la determinazione taglia caricabatterie adatto:
16A per ogni 100 Ah di batteria (Es.batteria 500 Ah:
16Ax5 = 80A).
Charge at decreasing current with intervention of the
final charge at 2.42 V/cell, final charge with timed
control 7h / 8h, 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 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).
