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 for any specific 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 overvoltage feature will operate. Overload of the output will cause the over current feature to operate. In either case, the cause must be 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 power supplies are UUCUL listed. They are manufactured in accordance with ISO 9001 quality assurance standards. These power supplies convert 90~264 Volt 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 component failure should operation in excessive environmental temperatures occur.

DuraComm LPX series power supplies are compatible with all LPH radio hoods. DuraComm LPX series power supplies may be configured for battery back up & charging applications with the addition of the LPBC-25. See www.duracomm.com for more 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 proper voltage.

Press the ON/OFF switch to the ON position and observe that the indicator light illuminates. If the indicator light fails to light, recheck the equipment 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 voltage from no load to full load. Slightly above the rated output load, the current 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 device must accept any interference received, including interference that may cause undesired operation.

LIMITED WARRANTY

DuraComm warrants to the initial end user, each power supply manufactured by DuraComm to be free from defects in material and workmanship when in normal use and service for a period of three years from the date of purchase from an authorized DuraComm dealer.

Should a product manufactured by DuraComm fail or malfunction due to manufacturing defect, or faulty component, DuraComm, at its option, will repair or replace the faulty product or parts thereof, which, after examination by DuraComm, prove to be defective or not operational according to specifications in effect at the time of sale to the initial end user. The product that is replaced or repaired under the provisions of this warranty will be warranted for the remainder of the original warranty period, only, and will not extend into a new three year warranty period.

The limited warranty does not extend to any DuraComm product which has been subject to misuse, accidental damage, neglect, incorrect wiring not associated with manufacture, improper charging voltages, or any product which has had the serial number removed, altered, defaced, or changed in any way.

DuraComm reserves the right to change, alter, or improve the specifications of its products at any time, and by so doing, incurs no obligation to install or retrofit any such changes or improvements in 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.
