6. Operating Instructions

6.1. 4-Digit Display & Power Calculation

The bright 4-digit LED display provides real-time readings of Voltage (V), Current (A), and Power (W). The display resolution is highly precise, up to 0.01V, 0.001A, and 0.1W, allowing for accurate monitoring of your output.

6.2. Auto C.V. and C.C. Mode

The Jesverty SPS series automatically switches between Constant Voltage (C.V.) and Constant Current (C.C.) modes based on the load. This ensures stable output even when the load changes. The C.V. and C.C. indicators (4 and 5) will show the active mode.

• Constant Voltage (C.V.) Mode: The output voltage remains constant at the set value, while the current varies according to the load.
• Constant Current (C.C.) Mode: The output current remains constant at the set value, while the voltage varies according to the load.

Note: The voltage and current settings you establish define the crossover point at which the mode automatically switches.

6.3. Voltage and Current Adjustment

Use the coarse and fine adjustment knobs for precise control:

• Coarse Adjustment (6, 7): Use the 'V-COARSE' and 'A-COARSE' knobs for large adjustments of voltage and current.
• Fine Adjustment (8, 9): Use the 'V-FINE' and 'A-FINE' knobs for precise, small adjustments. This allows for setting exact voltage and current limits.

6.4. USB Charging Function

The integrated 5V/2A USB port (10) allows for convenient charging of compatible USB-powered devices. This port features a fast charging protocol recognition chip.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your power supply.

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure the cooling fan (15) and ventilation openings are free from dust and obstructions. The fan is temperature-regulated and will operate as needed to prevent overheating.
• Fuse Replacement: If the unit does not power on, check the fuse located in the Fuse Box (17) at the rear. Disconnect the power cord before attempting to replace the fuse. A spare fuse is typically located inside the fuse box holder. Replace with a fuse of the same type and rating.
