PRODUCT DESCRIPTION
IOTA DLS Series Power Converter/Battery Chargers con-vert 220-240 volts nominal A.C. to volts D.C. As a power supply, its tightly controlled regulation allows the user to operate a D.C. load up to the converter’s rated output cur-rent. As a battery charger, the converter 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 that minimizes 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 converter will float-charge the battery to prevent self-discharge of its cells.
PROTECTION FEATURES
The IOTA Power Converters/Battery Chargers are de-signed with high quality components to help ensure years of continuous use. The unit is protected by multiple protection features for a long, trouble-free life.
- Reverse Battery Polarity Protection. 2) Brown-Out In-put 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.
INSTALLATION GUIDELINES
MOUNTING LOCATION
The IOTA Power Converter/Battery Charger 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. Provide at least 4″ around the
fan of the DLS to allow for proper air intake.
DO NOT mount the unit in a zero clearance compartment. DO NOT mount the DLS in
the same compartment with flammable items such as gasoline or batteries. There
are no components within the DLS unit that, during normal operation, produce
arcs or sparks. However, all electronic devices have some potential for
generating sparks in the event of failure which can result in explosion or
fire. DO NOT mount the DLS in an area that has the potential of dust, debris,
or other foreign materials to enter in through the DLS vents. DO NOT place the
DLS directly above the battery; the gases from the battery can corrode and
damage the DLS.
240 VOLT A.C. INPUT
Plug the unit A.C. input cord into an appropriate 220-240 volt 3-wire grounded
source. Refer to Illustration 2 for specifica-tions of the cord provided with
your DLS unit. See the Technical Specifications Chart on page 4 for maximum
current draw and required input voltages.
DO NOT USE EXTENSION CORDS – Using an improper exten-sion cord could result in
a risk of fire and electric shock, and may result in property damage, personal
injury or death.
DO NOT OPERATE THE DLS WITH A DAMAGED CORD OR PLUG. Have the cord or plug
replaced immediately by qualified service personnel.
To minimize the possibility of arcing at the battery, connect the IOTA power
cord to the AC input BEFORE connecting the battery. Note: occasionally a small
spark or arc may occur at the power outlet as the unit is plugged in. This is
a common occurrence due to the internal capacitors drawing power.
BATTERY CONNECTION
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. Recommended wire gauge and torque are as follows: 4-6 AWG at 45 in.
-lbs, 8 AWG at 40 in. -lbs. Refer to Illustration 1. Recreational vehicle
applica-tions require a type III circuit breaker be installed within 18″ of
the battery, connecting the battery positive to the line side of the breaker,
and the IOTA unit to the load side. Connect “Chassis Bonding Lug” on the IOTA
unit to vehicle chassis or other ground-ing source. Refer to Illustration 1.
REVERSE POLARITY FUSES
The IOTA Battery Charger/Power Supply is protected against reverse polarity on
the DC output. If a battery or the unit 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. Apply 5
inch-pound maximum torque. DO NOT OVERTIGHTEN. Note: some DLS models require
only one fuse. For these units, a small fiberglass spacer may be used in the
empty fuse slot to aid with tightening.
CHARGE CONTROL
TWO-STEP VOLTAGE JACK
The two-step voltage jack allows switching from a long-term float voltage to a
‘high-stage’ voltage. When the included dual voltage plug is inserted in the
jack*, the voltage rises to a bulk voltage for occasional fast charg-ing. When
the plug is removed, the voltage drops to the float voltage to reduce battery
water loss (voltages vary depending on the output ratings of the DLS).
WARNING: To avoid battery damage, remove the Dual Voltage Plug when quick-
charging is complete. NOTE: If the unit is equipped with an internal IQ4 smart
charger, two-step charging is not needed and the Dual Voltage Jack is
disabled.
THE IQ4 LED INDICATOR
(ONLY ON IOTA MODELS WITH INTERNAL IQ4)
IOTA Models with an internal IQ4 smart-charger give the user the benefit of
automatic Bulk, Absorption, and Float stage charging. This increases the
charging capacity of the IOTA charger, de-creases charge times and insures
proper and safe battery charg-ing without over-charging. The LED on the fan
end of the unit will indicate which charging phase the IOTA unit is currently
in. When the unit is first activated, the LED will flash as it reads the
number of cells in the battery. The unit will then proceed directly to the
Bulk charging or Float charging phase depending on the charge status of the
battery. Current DLS models utilize a three-color LED while earlier models
feature a single-color green LED. Refer-ence the appropriate LED CODE TABLES
below for the LED codes pertaining to your particular unit. Units that do not
have an internal IQ4 smart-charger can easily install an external IQ4 that
plugs into the available Dual Voltage Jack. Contact Customer Service for more
information.
Three-color LED Flashing code sequence intervals are 0.5 SEC on / 0.5 SEC off.
