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 individual applications are subject to
great variation, DuraComm makes no representation or warranty as to the merchantability, suitability or
fitness of these units foranyspecific application.
Precision regulated power supplies operate internally from voltages in excess of 13.8 volts. In rare
cases, voltage spikes or transients on the AC power line, or over heating, may cause a component failure
in the power supply. If this failure results in over voltage at the output terminals, the electronic over
voltage feature will operate. Overload of the output will cause the over current feature to operate. In
either case, the cause mustbe determined and corrected.
Failures require investigation as to the cause and/ or repair of the unit. THIS UNIT DOES NOT
HAVE ANY USER SERVICEABLE PARTS. SERVICE AND REPAIR MUST BE REFERRED TO QUALIFIED
PERSONNEL.
DESCRIPTION: The DuraComm LPX Series of powersupplies are UUCUL listed.They are manufactured in
accordance with ISO 9001 qualityassurance standards.These powersupplies convert90~264Volt
50/60 Hz AC input to low noise and ripple, regulated 13.8 volt DC output.
DuraComm 's power supplies are protected against inadvertent shorts and overloads by an
electronic output current limiting circuit.This current limiting circuit reduces the output limiting to a very
low and safe value until the overload is removed from the power supply. As soon as the overload is
removed, the output will be automatically restored.
Additionally the power supplies incorporate an over temperature feature to protect against
undesired componentfailure should operation in excessive environmental temperatures occur.
DuraComm LPX series powersupplies are compatible with all LPH radio hoods.
DuraComm LPX series power supplies may be configured for battery back up & charging applications
with theaddition of the LPBC-25. See www.duracomm.com formore information.
OPERATION: Connect your 12 volt DC device to the red (positive) and black (negative) output terminals.
Be certain you connect positive to positive (red) and negative to negative (black). Insert the AC plug into
an AC outlet of the propervoltage.
Press the ON/OFF switch to the ON position and observe that the indicator light illuminates. If the
indicator light fails to light, rechecktheequipment installation, hook-up polarity, and the AC outlet.
PRECAUTIONS: DO NOT block any openings in the case or operate the unit in a hot, enclosed
environment or compartment. Be sure adequate ventilation is provided since heat build-up will shorten
component life. NOTE: Most audio and radio equipment draws much less average current than the peak
demand.
If the unit stops working, check the 12 volt connections for tightness. If the unit fails again or
repeatedly, have the unit checked by a qualified technician. HAZARDOUS VOLTAGES EXIST INSIDE THE
UNIT . THERE ARE NO USER SERVICEABLE PARTS INSIDE. DO NOT EXPOSE THE UNIT TO RAIN OR MOISTURE.
Warning: The DuraComm series of desk top power supplies are accurately regulated to maintain output
voltagefrom no load to full load. Slightlyabove the rated output load, thecurrent limiting circuit begins
to act, reducing the output voltage to prevent unit overload damage.

NOTE: This device complies with part 15 of the FCC rules. Operation is subject to the
following 2 conditions; 1) This device may not cause harmful interference, and 2) This devi ce
must accept any interference received, including interference that may cause undesired
operation.

any time, and by so doing, incurs no obligation to install or retrofit any such changes or
improvementsin or on products manufactured prior to inclusion of such changes.
DuraComm requires any product needing in or out of warranty service to be returned to
DuraComm. All requests for warranty service must be accompanied by proof of purchase,
such as bill of sale with purchase date identified. DuraComm is not responsible for any
expenses or payments incurred for the removal of the product from its place of use,
transportation or shipping expenses to the place of repair, or return expenses of a repaired or
replacement product to its place of use .
The implied warranties that the law imposes on the sale of this product are expressly LIMITED,
in duration, to the three (3) year time period specified herein. DuraComm will not be liable for
damages, consequential or otherwise, resulting from the use and operation of thi sproduct, or

Notes 1. All parameters NOT specially mentioned are measured at 230VAC i, nput, rated load and 25 of ambient
temperature.
2. Peak current or peak power up to 3 seconds is provided .
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a
0.1 uf & 4 7uf parallel capacitor .
4. Tolerance: includes set up tolerance, line regulation and load regulation.
5. Line regulation is measured from low line to high line at rated load.
6. Load regulation is measured from 0% to 100% rated load.
7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may
lead to increase of the set up time.
8. Derating may be needed under low input voltages. Please check the derating curve for mo re detai ls.
9. The power supply is considered as an independent unit, but the final equipment still needs to re-confirm
that the whole svstem complies with the EMC directives.
