IOTA DLS SERIES Owner's Manual

The DLS series power converter/battery charger from
IOTA Engineering converts nominal A.C. voltage to D.C. As
a power supply, its tightly controlled regulation allows the
user to operate any appropriate nominal D.C. load up to
the converter's rated output current. 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 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.
WARRANTY
The DLS series power converter/battery charger is war-
ranted 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 complete
