GVDA DC Power Supply GD-G1203

The GVDA GD-G1203 is a versatile and precise DC-regulated power supply designed for laboratory and industrial applications. It offers adjustable voltage and current outputs, making it suitable for various testing and development tasks.

Specifications:

• Input Voltage: 220V AC
• Output Voltage: 0-120V DC
• Output Current: 0-3A DC
• Display: High-precision LED digital display showing voltage, current, and power simultaneously
• Protection Features: Overload protection, temperature-controlled fan for efficient cooling
• Additional Features: USB charging socket (5V 2A), continuously adjustable output, voltage and current presets

Precautions for Use:

1. Voltage Adjustment:
   • Gradually adjust the “Coarse” knob to approach the desired voltage, then fine-tune with the “Fine” knob for precise output. For example, to achieve a 12V output, set the “Coarse” adjustment slightly above 12V and fine-tune to exactly 12V.
2. Setting Voltage Before Load Connection:
   • Set the required voltage before connecting the load to ensure stability and prevent incorrect output.
3. Adjustments During Operation:
   • Disconnect the load before changing the “Coarse” adjustment. Set the new voltage, then reconnect the load.
4. Short Circuit or Overload Protection:
   • In case of a short circuit or overload, disconnect the load. Press the “Recovery” button or restart the power supply to resume normal operation. Ensure the issue is resolved before reconnecting the load.
5. Series Connection Guidelines:
   • When connecting power supply units in series, ensure the output current matches the lowest nominal current of the connected units.
6. Display Monitoring:
   • Use the built-in measurement display to monitor output voltage or current in different A/V states. The default setting displays voltage.
7. Output Connections:
   • Each channel has two output connectors:
     • Red (+): Positive output
     • Black (-): Negative output
     • The “Ground” symbol indicates a connection to the enclosure and serves as a safety wire.
8. Series Connection Restrictions:
   • Two voltages can be connected in series, but simultaneous use is prohibited. Avoid prolonged short circuits at the output terminals to prevent damage.

Package Includes:

• 1 x GD-G1203 DC Power Supply Unit
• 1 x Power Cable
• 1 x Pair of Crocodile Clip Leads

The GD-G1203 ensures stable, safe, and accurate power delivery for various applications, making it a reliable choice for professionals and enthusiasts alike.
