WARNING: The individual user should take care to determine prior to use or installation
whether this device is suitable, adequate, or safe for the use intended. Since applications
are subject to great variation, DuraComm makes no representation or warranty as to the

DESCRIPTION:The LP-18BC desktop power supply is UL & CUL recognized and
manufactured to ISO 9001 quality assurance standards. These power supplies convert AC
or DC input into low noise and ripple, regulated 13.8 volt DC output. The LP-18BC has
a built in battery back up and charging circuit with diode isolation for seamless transfer to
battery if input power is disrupted. Once input power is restored the LP-18BC will
automatically recharge the battery with 1.5 amps of trickle charging.
The LP-18BC contains a low voltage cutoff circuit which provides for low voltage
disconnect when the battery reaches 11.0 volts to prevent battery & load damage.
Note: Diagram reflects LP-18BC with Battery & Load
INSTALLATION
1. LOAD- Connect your 12 volt DC device using UL wiring to the LP-18BC
terminal output marked V (-) and V (+). Be certain to connect Positive (+) to
Positive (red) and Negative (-) to Negative (black).
2. BATTERY- Connect your 12 volt DC battery using UL wiring to the LP-18BC
terminal marked B (+) and B (-). Be certain to connect Positive (+) to Positive
(red) and Negative (-) to Negative (black).
Note: It is not recommended to connect 2 or more batteries as this will delay
charging time and if one battery fails it may cause other to malfunction.
OPERATION:Insert Power cord into an outlet of the proper voltage.
Press the ON/OFF (- / O) switch to the “ON” (-) position and observe if indicator
light on front of unit illuminates. If the indicator fails to light, re-check the
equipment installation.
