DLS-54-13 Battery Charger
  INPUT VOLTAGE
  108-132 VAC

  INPUT FREQUENCY
  50-60 Hz

  OUTPUT VOLTAGE
  54.4 VDC

  OUTPUT AMPERAGE
  13 Amps



The DLS-54-13 Power Converter/Battery Charger from IOTA Engineering converts nominal 108-132 AC voltage to 54.4 DC voltage for 48V battery charging.

As a battery charger, the unit will maintain the battery, delivering its full-rated current when the battery capacity falls sufficiently low. The voltage is set to deliver its maximum current for the necessary period of time to minimize undue stress to the battery caused by heating of its cells. This helps to ensure the longest possible life of the battery. Over time, as the battery nears its full capacity, the DLS-54-13 will automatically drop the current, providing a float-charge to the battery to prevent self-discharge of the cells.




Model Features DLS-54-13
The DLS-54-13 provides AC/DC conversion up to 13 amps and features a Dual Voltage Jack, allowing the user to manually select between a normal 54.4V charge or a stepped-up charge for faster charging.


DLS-54-13/IQ4
The DLS-54-13/IQ4 features an internal IQ4 Smart Charge Controller which automatically provides four-stage battery charging for safer charging and longer life for your system's battery.
