4. Setup

Follow these steps to set up your Jesverty SPS-1352 power supply:

1. Unpacking: Carefully remove the power supply from its packaging. Inspect for any signs of damage.
2. Placement: Place the unit on a stable, flat surface with adequate clearance around all sides for proper ventilation. Ensure it is away from direct sunlight, heat sources, and moisture.
3. Power Connection:
   • Ensure the power ON/OFF switch on the front panel is in the "OFF" position.
   • Connect the provided AC power cord to the AC Input Socket on the rear panel of the power supply.
   • Plug the other end of the AC power cord into a suitable grounded wall outlet.
4. Connecting Load:
   • Before connecting any device, ensure the power supply is OFF and the device to be powered is also OFF.
   • Connect your device to the appropriate output terminal (Anderson, Cigarette Plug, or Rear Terminal) ensuring correct polarity (positive to positive, negative to negative).
   • Verify that the current draw of your connected device does not exceed the maximum rating of the chosen output terminal or the overall power supply.

5. Operating Instructions

Once the power supply is set up and your devices are connected, follow these steps for operation:

1. Power On: Flip the Power ON/OFF switch to the "ON" position. The digital meter will illuminate, displaying the current voltage and amperage.
2. Voltage Selection:
   • For a fixed 13.8V output, ensure the 13.8V Fixed/Adjustable switch is in the "13.8V" position.
   • For adjustable voltage (9-15V), set the switch to the "ADJ" position. Then, rotate the Voltage Adjust knob to set the desired output voltage. Observe the digital meter for the precise voltage reading.
3. Connecting Devices:
   • Anderson Connectors: Use for high-current devices up to 45A. Ensure secure connection.
   • Cigarette Plug Terminal: Suitable for devices up to 10A.
   • Rear Output Terminal: Provides the full 50A capacity. Ensure proper wiring with appropriate gauge wire.
   • USB-C Ports: For charging USB-powered devices (5V/2A).
4. Noise Offset Adjustment: If experiencing interference, particularly with radio communications equipment, slowly rotate the Noise Offset knob to find the optimal setting that minimizes noise.
5. Monitoring: Continuously monitor the digital meter for voltage and amperage readings to ensure your devices are operating within their specified limits and the power supply is not overloaded.
6. Power Off: When finished, turn off all connected devices first, then flip the Power ON/OFF switch on the power supply to the "OFF" position. Disconnect the power cord from the wall outlet if the unit will not be used for an extended period.
