Accumulator chargers NB

NB
	Up to 150 W 12 V or 24 V version Input – power cord Output – crocodile clips Protection IP20

Accumulator chargers NB series are intended for charging of 12 V or 24 V lead-acid accumulators. Charging is running according to IU characteristics. At the beginning the accumulator is charged with a constant current. When the voltage on the accumulator reaches the value of 14,4 V (or 28,8 V), charging then continues in mode with constant voltage. When the charging current decreases to approximately 2/5 of maximum charging current, the signalization LED switches from red to green which signalizes that the accumulator is charged.

The version .1 of charger has IUUo charging characteristics. When the charging current decreases to approximately 2/5 of maximum charging current, the output voltage of the charger will lower to 13,8 V (or 27,6 V). This allows the charger to be permanently connected to the accumulator without it being overcharged. This version is suitable for keeping the accumulator in constantly charged state.

NBA
	Up to 100 W 24 V or 36 V model Input – power cord Output – cable Sturdy aluminium cover Protection IP65

 

Accumulator charger model NBA is designed to charge lead-acid accumulators with nominal voltage of 24 V or 36 V. Charging is according to IUUo characteristics with the option of temperature compensation of output voltage. Chargers NBA is manufactured with higher mechanical endurance, which allows them to be mounted directly into a vehicle.
