220VAC DLS SERIES POWER CONVERTER/CHARGER
OWNER’S MANUAL
The DLS series power converter/battery charger from
IOTA Engineering converts 220 volts AC to volts DC. As
a power supply, its tightly controlled regulation allows the
user to operate a 12 volt nominal load up to the converter’s
rated output current (refer to specification chart for input/
output ratings). 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 pos-
sible 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 DLS series power converter/battery charger is de-
signed 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 addi-
tion, 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.
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. For
