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
