Iota Engineering DLS-30 Regulated Battery Charger 12 Volt 30 Amp

Product description

The DLS-30 Power Converter/Battery Charger from IOTA Engineering converts nominal 120 AC voltage to 13.4 DC voltage for both DC load operation and 12V battery charging.

As a power supply, the unit’s tightly controlled regulation allows the user to operate a nominal 12VDC load up to 30 amps.

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-30 will automatically drop the current, providing a float-charge to the battery to prevent self-discharge of the cells.

Tight line-load regulation ensures that the output voltage holds steady from no load to full load. This keeps pumps, motors, and lights working at the correct voltage even during brown out situations.

During times of heavy load demands, the automatic circuitry will activate the fan before thermal stress can occur on any internal components. Reliability and durability is built into all DLS models. In the event the batteries or the DLS unit is wired incorrectly, the DLS converter/power supply is protected from damage. External fuses can be quickly and easily replaced.
