Input Voltage Selection The power supply is set up for 230V AC input as shipped from the factory. For 115V AC applications, set the recessed 115/230 input select switch located on the rear of the power supply into the proper position. Positions are identified on the switch. Use a small screwdriver to slide the switch into position. No adjustment is necessary for either 50 or 60 Hz input. Applications Land mobile radio base stations Communications systems Security systems Automotive & marine systems OEM applications Test equipment Electronic displays 12 Volt lighting systems GPS receivers DC computers . Package Contents Power Supply AC Power Cord, 4 ft. . Installation Instructions Unplug the power supply from the mains supply outlet. Select the correct input voltage (See Input Voltage Selection). Connect the power cable’s positive (red) wire to the positive terminal and connect the negative (black) wire to the negative terminal on the back of the power supply. Plug the AC power cable into the power socket on the back of the radio. Plug the power supply into the main AC wall outlet. . Turning the power supply on Turn the power supply on by pressing the power switch to the ‘ON’ Position. Turning the power supply off Before you turn the power supply off, turn the radio off as described in the user documentation for the radio. Then turn the power supply off by pressing the power switch to the ‘OFF’ Position. Cooling The SPS-30DM power supply is cooled by convection and forced air cooling (normal airflow around the power supply in combination with a temperature controlled fan to improve cooling at higher levels of use). The fan is temperature activated and the speed is controlled by a sensor. When the temperature rises, the fan speed increases. Warranty The Powerwerx support policy is simple: we want you to be happy! If you have a problem, please feel free to contact us and we will do our best to get you up and running as soon as possible. Powerwerx power supplies have a three-year limited warranty. SPS-30DM : Variable 30 Amp Desktop DC Power Supply
