The DLS-27-15 battery charger/power converter from IOTA Engineering converts nomi-
nal 120V A.C. voltage to 27.2V 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 DLS-27-15 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.

APPLICATION
Charging for 24V Battery Systems and Operation
of 24VDC systems and accessories.
FEATURES
Switch-mode technology
Current limit, thermal and overload
protection
Lower operating temperature
Clean and steady DC Output operates
your loads the way they were intended,
avoiding potential damage to systems
from errant DC voltage.
Built-in protection features guard
the unit against erratic line voltage
that can occur from shore power or
generator supplies.
Reverse Polarity Protection to protect
against damage from incorrect battery
hook-up, using readily available fuse
types that are easy to replace.
Proportional fan control for
whisper-quiet operation.
ADDITIONAL FEATURES INCLUDE...
Compatible with IOTA IQ
Smart Charger for automatic
four-stage charging.
Charging Jack option for normal
and high-stage battery charging
applications.
Covered by IOTA with a full
two-year warranty.
