Iota Engineering DLS-240-27-40 Battery Charger Without IQ4, 240 Volt AC Input, 24 Volt 40 Amp

Product description

The DLS-240-27-40 features a dual voltage jack which allows switching from a long-term float voltage of 27.2VDC to a higher voltage rapid charge by simply inserting the dual voltage plug (included) into the jack. The charger can accept input voltages between 220 volts AC and 240 volts AC.

NOTE: This model is not available with a built-in IQ4 smart charger. However, it is compatible with the external IQ4 that plugs in to the DLS-240-30 charger. There is no difference in performance between a built-in vs external IQ4.

For charging 24 volt DC batteries or battery banks from a 240 volt AC power source.
