Safety Information

WARNING:

• High voltage may be present. Risk of electric shock.
• Do not open the casing. Refer servicing to qualified personnel.
• Ensure proper grounding.
• Do not operate in wet or damp conditions.

CAUTION:

• Avoid exposing the unit to extreme temperatures or humidity.
• Do not overload the power supply beyond its rated capacity.

IMPORTANT:

• Read all instructions before operating the equipment.
• Keep this manual for future reference.

Specifications

The SPPS-D Series DC Power Supply offers various output configurations. Key specifications include:

CV/CC Operation: The power supply operates in Constant Voltage (CV) mode. If the load resistance decreases and the output current increases to the set current value, the power supply automatically switches to Constant Current (CC) mode. In CC mode, the current remains at the set value, and the voltage is proportionally reduced. To restore CV output, increase the load resistance or the current set value.

Operation Instructions

Main Unit Diagram:

[Diagram: Front panel of the NICE-POWER DC Power Supply showing a digital display, control knobs for voltage and current, output terminals (positive and negative), and buttons for mode selection (CV/CC), output on/off, and possibly a lock function. The display shows numerical values for voltage and current.]

Basic Operation:

1. Connect the power cord to a grounded AC outlet.
2. Set the desired output voltage and current using the control knobs.
3. Connect the load to the output terminals. Ensure correct polarity.
4. Press the output switch to enable power output. The display will show the actual output voltage and current.
5. To disable output, press the output switch again.

CV/CC Mode Transition:

The power supply automatically transitions between Constant Voltage (CV) and Constant Current (CC) modes based on the load conditions. The display typically indicates the current operating mode.

Product Usage

This DC power supply is suitable for various applications, including:

• Laboratory testing and research
• Educational purposes
• Electronic circuit development and debugging
• Powering electronic devices requiring stable DC voltage and current

Ensure the power supply is used within its specified voltage and current limits.

Troubleshooting

Problem: No output voltage.

Possible Cause: Output switch is off, or overload protection is active.

Solution: Ensure the output switch is on. Check for short circuits in the load and reset if necessary.

Problem: Output voltage is unstable.

Possible Cause: Load is fluctuating, or power supply is operating near its limits.

Solution: Ensure the load is within the power supply's specifications. Check for loose connections.

Problem: Unit overheats.

Possible Cause: Overload, poor ventilation, or internal fault.

Solution: Reduce the load. Ensure adequate ventilation. Contact support if the issue persists.
