OWON SP6103 Single Channel DC Power Supply User Manual

1. Introduction

The OWON SP6103 is a high-performance single-channel linear DC power supply designed for various applications requiring stable and precise power. This unit provides a maximum output of 60V and 10A, with a total power output of 300W. It features a 3.7-inch TFT LCD for clear display of parameters, low ripple and noise, and essential protection functions such as over-voltage (OVP) and over-current (OCP) protection. The SP6103 supports both Constant Voltage (CV) and Constant Current (CC) output modes and includes an RS232 port for remote control via SCPI commands.

2. Safety Instructions

To ensure safe operation and prolong the lifespan of your OWON SP6103 power supply, please read and adhere to the following safety guidelines:

• Power Source: Connect the unit only to a power source that matches the voltage and frequency specified on the product label. Ensure the power cord is properly grounded.
• Ventilation: Do not block the ventilation openings on the sides and rear of the unit. Adequate airflow is essential to prevent overheating.
• Environment: Operate the power supply in a dry, well-ventilated indoor environment. Avoid exposure to moisture, dust, direct sunlight, or extreme temperatures.
• Load Connection: Always connect the load to the output terminals before turning on the output. Ensure correct polarity.
• Output Terminals: Do not touch the output terminals when the output is active. High voltage and current can cause electric shock.
• Maintenance: Refer all servicing to qualified personnel. Do not attempt to open or repair the unit yourself.
• Cleaning: Disconnect the power cord before cleaning. Use a soft, dry cloth. Do not use liquid cleaners or aerosols.

4. Setup

Follow these steps to set up your OWON SP6103 power supply:

1. Unpacking: Carefully remove the power supply from its packaging. Inspect the unit for any signs of damage during transit.
2. Placement: Place the unit on a stable, level surface, ensuring adequate space around the ventilation openings for proper airflow.
3. Power Connection: Connect the provided AC power cord to the power input on the rear panel of the SP6103, then plug the other end into a grounded AC outlet.
4. Initial Power On: Flip the main power switch on the front panel to the 'ON' position. The display should illuminate.
5. Load Connection: Before activating the output, connect your load to the output terminals. Connect the positive (+) terminal of your load to the red (+) terminal of the power supply, and the negative (-) terminal of your load to the black (-) terminal of the power supply. If grounding is required, connect to the green (Ground) terminal.

5. Operating Instructions

5.1 Setting Voltage and Current

To set the desired output voltage and current:

1. Ensure the output is OFF (the 'On/Off' button LED is off).
2. Use the navigation buttons (Left/Right) to select the parameter you wish to adjust (Voltage or Current). The selected parameter will be highlighted.
3. Rotate the Knob to adjust the value. Press the OK button to confirm the value or move to the next digit for fine adjustment.
4. Repeat for both voltage and current limits.

5.2 Activating Output

After setting the desired voltage and current limits, press the On/Off button to activate the output. The LED on the button will illuminate, and the actual output voltage and current will be displayed.

5.3 Constant Voltage (CV) / Constant Current (CC) Mode

The SP6103 automatically operates in either Constant Voltage (CV) or Constant Current (CC) mode depending on the load. If the load resistance is high, the unit will operate in CV mode, maintaining the set voltage. If the load resistance is low, causing the current to reach the set limit, the unit will switch to CC mode, maintaining the set current and reducing the output voltage.

5.4 Over-Voltage Protection (OVP) and Over-Current Protection (OCP)

The SP6103 includes OVP and OCP features to protect the connected load and the power supply itself.

• Setting OVP/OCP: Access the OVP/OCP settings through the System menu or dedicated display area. Use the navigation buttons and knob to set the desired protection thresholds.
• Triggering Protection: If the output voltage or current exceeds the set OVP or OCP limits, the output will automatically shut down, and an indicator will appear on the display.
• Resetting Protection: To clear a protection trigger, turn off the output, resolve the condition that caused the trigger, and then turn the output back on.

5.5 Memory Functions

The Memory button allows you to save and recall frequently used voltage and current settings. Consult the on-screen prompts for saving to and recalling from memory slots.

5.6 Keylock Function

Press the Keylock button to disable the front panel controls, preventing accidental changes to the output settings during operation. Press it again to unlock.

5.7 RS232 Communication

The SP6103 features an RS232 port for remote control and data logging. It supports Standard Commands for Programmable Instruments (SCPI). Refer to the detailed programming manual (if available from the manufacturer) for specific SCPI commands and communication protocols.

6. Maintenance

The OWON SP6103 requires minimal maintenance to ensure optimal performance:

• Cleaning: Regularly clean the exterior of the unit with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents. Ensure the unit is powered off and unplugged before cleaning.
• Ventilation: Periodically check that the ventilation openings are free from dust and debris. Use compressed air to gently clear any blockages if necessary.
• Storage: When not in use for extended periods, store the power supply in a cool, dry place, away from direct sunlight and extreme temperatures.
