12V 20A Programmable Chargers
1220 - 12 Volts 20 Amp 300 Watts Programmable Battery Charger
Nickel-zinc or lead-acid (flooded, sealed, and traction) batteries may be charged accordingly to battery manufacturer specifications. Up to five charging phases may be enabled to charge the battery with constant current, constant voltage or floating charge. For each of the charging phases a lot of parameters may be set as: max current and voltage, max. Charging time for that phase etc. Each charging phase (except the first one) may be conditionally executed after a defined number of AH put into the battery or after a defined number of completed 1st charging phases.
The fully automatic equalization charging phase is achievable with standard parameter set-up and may be executed after every completed charging or after pre-defined number of charging or charged AHs. programmable automatic to-up cycle prevents self discharge during non-operational periods - charger starts charging after a pre-defined number of day or when the battery voltage is lower than the parameter value. The charger is fully re-programmable without opening the box. The software for the PC and IF adapter is all what you need.

The max current at 14.7V = 20.4 Amps and time limit (phase 1) is 8-12 hours on standard profile.
Note 1: time out, charge finished charge after time limit in phase 2 or 3.
The max and min. charge currents time limits may vary with charger application i.e. size and chemistry of the battery.
THE LED INDICATION
Phase 1 and phase 2 : Yellow LED blinks fast
Phase 3: Yellow LED blinks slow
After time limit reached, the green LED turns on (it means that the battery is fully charge).
