IOTA DLS2740
Battery Charger / Power Converter

The DLS 27-40 features a Two-Step Voltage Jack which allows switching from a long-term float voltage to an increased rapid charge by simply inserting the dual voltage plug (included) into the jack.

The DLS 27-40 is also available with an IQ smart-controller already integrated into the unit which converts the charger into a 3-stage "smart" charger, increasing the performance of your DLS 27-40.

27V thru 48V DLS Power Converters/Battery Chargers provide quality service and protection for a wide range of voltage applications. Each features the Dual Voltage Jack for easy two-step charging, external and internal IQ controller option compatibility, and are backed by our standard Two-Year Warranty.

Using state-of-the-art, switch-mode technology, the DLS Power Supply series is engineered with the user and variable environmental conditions in mind. Extra care has been given to insure many years of service-free operation, even when subjected to extremely harsh conditions. Batteries are charged quickly and efficiently without over charging and pumps, motors, and fans operate perfectly for prolonged life.

IOTA Engineering uses advanced switch mode technology to bring to market highly sophisticated electronic converter/power supplies at appealing affordability.

Exceptionally clean DC output insures pumps, motors, fans, and lights work perfectly. This means longer life for any connected load; virtually no AC ripple to cause static or premature failure of radio or television equipment.

The DLS series converter/charger quickly and efficiently charges batteries from the full rated output of the DLS. The DLS then maintains the batteries, only putting into the battery what is required by load or self discharge, cutting back to milliamps as the battery requires.

Low and transient AC line voltage is a major cause of converter/power supply failure. The DLS series converter/power supply is protected against low line voltage, as well as spikes coming from the AC power source or from improperly adjusted generators.

The DLS series converter/power supply meets F.C.C. criteria, minimizing radio and television equipment interference, especially on the lower frequency bands.

The DLS series converter/power supply can be used with or without a battery. When used as a converter/power supply, the DLS model will only supply what is required by the load. When not in use it is essentially off, reducing electricity usage.

Even in its subcompact size, the DLS series converter/power supply, at full load, has an operating temperature half that of some switch mode electronic models. This means substantially longer life and safer operation.

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.

Proportional Fan Circuitry provides an extra measure of protection. 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 quic

 


PROTECTION FEATURES

The DLS series power converter/battery charger is designed with high quality components to help ensure years of continuous use. The DLS series is protected by multiple protection features for a long, trouble-free life. 1) Reverse Battery Polarity Protection. 2) Brown-Out Input Protection. 3) Over-Current Protection - cycle by cycle peak limiting as well as rated current limiting to maximize the life of the converter. 4) Over-Temperature Protection. In addition, it is designed with a unique “proportional” fan control circuit. Fan speed is directly proportional to the converter’s internal ambient temperature. This enables the fan to turn on and off very slowly, minimizing unwanted fan-starting noise.

WARRANTY

The DLS series power converter/battery charger is warranted from defects in materials or workmanship for two years from date of retail purchase, and limits the remedies to repair or replacement. This warranty is valid only in the continental United States and Canada.

INSTALLATION GUIDELINES

There are no components within the DLS unit that, in their normal operation, produce arcs or sparks. However, all electronic devices have some potential for generating sparks in the event of failure. Therefore, never install this device in the same compartment with flammable items such as gasoline or batteries.

MOUNTING LOCATION
The DLS battery charger/power supply can be mounted in any position within an enclosed or interior compartment. Provide sufficient air space to allow unrestricted airflow in and around the unit.

DLS INSTALLATION
Disconnect the positive side of the battery before installation. Connect the positive (red) and negative (black) terminal lugs to battery or load. Always use the proper size wire based on the amperage of the converter and the battery. When connecting to a battery, a breaker should be installed within 18” of the battery, connecting the battery positive to the line side of the breaker, and the DLS to the load side. Connect “Chassis Bonding Lug” on the DLS to vehicle chassis or other grounding source.

120 VOLT A.C. INPUT
Plug the DLS A.C. input cord into a 120 volt 3 wire grounded source. See chart for maximum current draw and required input voltages.

REVERSE POLARITY FUSES
The DLS Battery Charger/Power Supply is protected against reverse polarity on the DC output. If a battery or the DLS is hooked up incorrectly, the fuses will blow and can be easily replaced. Always use the same size and style fuse that came with the converter. To change the fuses, use a screwdriver to loosen the screws and remove the fuses. Always replace the fuses with the same type and rating. After inserting the new fuses, tighten the screws firmly. DO NOT OVERTIGHTEN.

CHARGE CONTROLLER OPTIONS

Charge Controller Options are designed for DLS units that DO NOT have the IQ SMART CONTROL FEATURE internally integrated. It is not necessary to utilize the Dual Voltage Jack or External IQ Controller for IQ-integrated DLS units.

Dual Voltage PlugTWO-STEP VOLTAGE JACK
The two-step voltage jack (located on the top of the DLS on the fan-end of the unit) allows switching from a long-term float voltage of 13.6vdc up to 14.2vdc. When the included dual voltage plug is inserted in the jack, the voltage rises to 14.2vdc for occasional fast charging. When the plug is removed, the voltage drops to 13.6vdc to reduce battery water loss. WARNING: To avoid battery damage, remove the Dual Voltage Plug when quick-charging is complete.

IQ ControllerIQ SMART CHARGER
DLS power converters/chargers are designed to accommodate the IQ smart charge controller. The microprocessor- controlled charger turns the DLS charger into an “automatic” 3-stage “smart charger,” giving the user the benefit of Bulk, Absorption, and Float stage charging. This increases the charging capacity of the DLS charger, decreases charge times and insures proper and safe battery charging without over-charging. The IQ controller inserts into the dual voltage jack on the DLS.
