IOTA DLS Series User manual

220VAC DLS SERIES POWER CONVERTER/CHARGER
OWNER’S MANUAL
TheDLSseriespowerconverter/batterychargerfromIOTA
Engineeringconverts 220 volts nominal A.C. to 13.6 volts
D.C. As a power supply, its tightly controlled regulation
allows the user to operate any 12 volt nominal D.C. load
up to the converter’s rated output current. As a battery
charger, the converter will maintain the battery, deliver-
ing its full-rated current when the battery capacity falls
sufficiently low. The voltage is set to deliver its maxi-
mum current for the necessary period of time that mini-
mizes 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
TheDLSseriespowerconverter/batterychargerisdesigned
withhigh quality components to help ensure years of con-
tinuous use. The DLS series is protected by multiple pro-
tection 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-Tem-
perature Protection. In addition, it is designed with a
unique “proportional” fan control circuit. Fan speed is
directly proportional to the converter’s internal ambi-
ent temperature. This enables the fan to turn on and
off very slowly, minimizing unwanted fan-starting noise.
The DLS series power converter/battery charger is war-
ranted from defects in materials or workmanship for two
yearsfromdateofretailpurchase,andlimitstheremedies
to repair or replacement. This warranty is valid only in the
continentalUnited States and Canada. For complete war-
ranty details, contact Customer Service or visit

thefan-endoftheunit)allowsswitchingfrom along-termfloat
voltageof13.6vdcupto14.2vdc.Whentheincludeddualvolt-
age plug is inserted in the jack, the voltage rises to 14.2vdc
for occasional fast charging. When the plug is removed, the

ING: To avoid battery damage, remove the Dual Voltage
Plug when quick-charging is complete.
There are no components within the DLS unit that, in their normal operation, produce arcs or sparks. However, all
electronicdeviceshave some potentialfor generating sparksin the event offailure. Therefore, neverinstall this device
in the same compartment with flammable items such as gasoline or batteries.
INSTALLATION GUIDELINES
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.
Connectthe positive(red)andnegative(black)terminallugs to
battery or load. Always use the proper size wire based on the
amperageoftheconverterandthebattery.Whenconnectingto
abattery,abreakershouldbeinstalledwithin18”ofthebattery,
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.
220 VOLT A.C. INPUT
The 220VAC DLS provides a three prong AC cord termi-
nal for connection to the AC power source. The cord is
not provided. Consult your local supplier for the AC cord
that meets the requirements of your individual applica-
tion. Refer to the chart for maximum current draw and
requiredinputvoltages.

CHARGE CONTROLLER OPTIONS
IQ SMART CHARGER
DLS power converters/chargers are designed to accom-
modate the IQ smart charge controller. The microproces-
sor-controlledchargerturnstheDLScharger into an “auto-
matic” 3-stage “smart charger,” giving the user the benefit
of Bulk, Absorption, and Float stage charging. This in-
creases the charging capacity of the DLS charger, de-
creases charge times and insures proper and safe battery
charging without over-charging. The IQ controller inserts
into the dual voltage jack on the DLS.
ChargeController Optionsare designedforDLS unitsthat DONOT havethe IQSMART CONTROLFEATUREinternally
integrated.For units that feature an internal IQ controller, the Dual Voltage Jack is disabled.
