ISO - 8U Eight Output Isolated Power Supply With USBUser's ManualIMPORTANT SAFETY INSTRUCTION – READ FIRSTThis symbol, whenever it appears alerts you to the presenceof uninsulated dangerous voltage inside the enclosure-voltage that may be sufficient to constitute a risk of shock.This symbol, whenever it appears, alerts you to importantoperating and maintenance instructions in theaccompanying literature. Please read the manual.Read Instructions: Retain safety and operating instructions for future reference. Heed all warnings printed here and on the equipment. Follow the operating instructions printed in this user manual.Do not open: There are no user serviceable parts inside. Refer any service work to qualified technical personnel only.Environment: Protect from excessive dirt, dust, heat, and vibration when operating and storing. Avoid tobacco ash, drink spillage and smoke, especially that associated with smoke machines.Handling: Protect the controls from damage during transit. Use adequate padding if you need to ship the unit. To avoid injury to yourself or damage to the equipment, take care when lifting, moving or carrying the unit.Servicing: Refer servicing to qualified technical personnel.Installation: Install the unit in accordance with the instructions printed in the user manual.INTRODUCTIONThank you for purchasing Applied Research and Technology’s ISO-8U. Two high power outputs can provide 250mA. All other outputs are capable of providing up to 100mA. There is one variable voltage output to simulate worn batteries.Each output is individually current limited and short circuit protected. An Output status indicator goes out when there is a fault (i.e., short, current protection or temp overload).A USB type A jack can provide high power charging up to 10Watts. The charging port will remain active as long as the unit is powered by the external supply.The unit comes with a wide variety of cables to connect your pedals including battery clip adapters, large and small diameter power plugs, and “Y” for expanding the number of devices you can connect and even a polarity reversing cable. FEATURES∙Eight Isolated DC Outputs∙One Adjustable Output∙Each Output Has a switchable voltage∙USB Power jack for high-speed charging∙Comes with multiple adaptor cords∙Runs off a Universal power supply∙Tie wrap slots for clean wire routing∙Perfect for powering guitar pedals, and pedal boards1Designed and developed in the USA INSTALLATION and OPERATION2Status LED’sThese LEDs remain lit as long as there are no electrical faults with the cabling or the pedal you are supplying power too. If a particular fault seen at one of the outputs, the LED dim or turn off and the voltage at that output will diminish. The cable connection on the output with the fault will have to be removed and reconnected for the output to be reset.SAG VoltageTo enable this function on voltage output1 the dip switch will need to be set to 4-9v. Then the user can vary the voltage from the pot on the unit face.3APPLICATIONSThe ART ISO-8U is designed so that it can be mounted on a pedal base using Velcro. The front and sides are recessed to protect the cables and controls.The bottom edge of the ISO-8U has slots that allow you to use cable ties to control the routing of the power cables. Once you loosely insert the wire ties through the slots you can run the power cables through the remaining loops. Once all of the cables are in place, you can tighten down the wire ties.45Cable Choices Qty Cable Description6 - 24-inch straight barrel 5.1mm to 5.1mm barrel 2 - 24-inch Rt. Angle 5.1mm to 5.1mm barrel1 - Battery clip to 5.1mm barrel1 - Polarity reversal 5.1mm to 5.1mm barrel1 - “Y” cable (5.1mm) barrel1 - 3.5mm barrel to 5.1mm barrelPowering your PedalsThe first step in using the ART ISO-8U to power your device, would be to make sure that pedal device you want to use can be powered by a dc supply. The range on the ART ISO-8U is 9 or 12vdc or combining to outputs to achieve 18 or 24vdc, remember that there is a max current draw on each output. Then verifying the polarity of the pedal device, you are wanting to power. Generally, 9V battery powered devices will draw less that 100mA.The ART ISO-8U uses the negative center pin configuration.This will determine if you need to use the polarityreversal cable or one of the standard cables. Thiswill allow you to use a pedal that has a positivecenter pin. Before you connect the cable from the unit, make sure you set the dipswitch to the appropriate voltage (9v or 12v).If you have a pedal device that does not have a power jack and is powered by a 9V battery, then you can use the cable that has the battery tab connector.There is a limitation on current loading, as this unit is not meant to run all of the outputs at their maximum current draw.6WARRANTY INFORMATIONLimited WarrantyApplied Research and Technology will provide warranty and service for this unit in accordance with the following warrants: Applied Research and Technology, (A R T) warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials for a period of three years from the date of purchase.
