4. Opsætning

Follow these steps to set up your VOLTCRAFT VLP-1303 USB power supply.

Figur 3: Side view of the VLP-1303 USB with extended feet. The power supply can be tilted for better viewing and access to controls by extending its front feet, ensuring stability during operation.

1. Udpakning: Carefully remove the power supply from its packaging. Retain the packaging for future transport or storage.
2. Placering: Place the unit on a stable, flat, and non-conductive surface. Ensure there is sufficient space around the unit for proper air circulation, especially around the rear cooling fins. You may extend the front feet for a tilted viewvinkel.
3. Strømtilslutning: Connect the supplied AC power cord to the power input socket on the rear panel of the power supply and then to a suitable grounded wall outlet.
4. Første gang tændt: Flip the main power switch on the front panel to the 'ON' position. The digital display should illuminate.

5. Betjeningsvejledning

This section details the operation of the main output and the USB ports.

5.1 Main Output (0-30V, 0.01-3A)

1. Indstilling Voltage: Drej på VOLT knob to adjust the desired output voltage. The 10-turn potentiometer allows for very fine adjustments. Observe the voltage reading on the digital display.
2. Indstilling af strømgrænse: Drej på AMPERE knob to set the maximum current limit. This protects your connected device from drawing excessive current. The 'C-LIMIT' indicator will light up when the current limit is reached.
3. Tilslutningsbelastning: Connect your device to the main output terminals. Ensure correct polarity (red for positive, blue for negative). The yellow terminal is for ground.
4. Overvoltage-beskyttelse (OVP): The OVP function protects your load from excessive voltage. Adjust the OVP level using the OVP ADJ control. If the output voltage exceeds this set level, the power supply will shut down the output.

5.2 USB Test and Development Port (USB-B1)

This port is designed for testing USB devices and simulating various USB power conditions.

• Voltage Justering: Voltage of USB-B1 can be continuously adjusted from 3.9V to 6.2V. A detent at 5.1V assists in setting standard USB voltage.
• Current Limiter: A freely adjustable current limiter allows you to simulate a USB port providing less than 500mA, useful for testing device behavior under low current conditions.
• Undervoltage/Overvoltage: Specific undervoltage og overvoltage settings can be configured for this port to test device resilience.

5.3 Quick Charge 2.0 Port (USB-B2)

The USB-B2 port provides Quick Charge 2.0 functionality, independent of the main output and the USB-B1 test port. Use this for fast charging compatible devices.

6. Vedligeholdelse

Proper maintenance ensures the longevity and reliable operation of your power supply.

• Rensning: Disconnect the power supply from the mains before cleaning. Use a dry, soft cloth to wipe the casing. Do not use abrasive cleaners, solvents, or harsh chemicals.
• Ventilation: Periodically check that the ventilation openings and cooling fins on the rear are free from dust and debris. Use compressed air if necessary to clear blockages.
• Opbevaring: When not in use for extended periods, store the power supply in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
• Udskiftning af sikring: If the unit does not power on, check the fuse located in the fuse holder on the rear panel. Replace it only with a fuse of the same type and rating (e.g., T 1.6A / 250V).
