Front Panel Controls:
- Simba Chinja: Inoshandura iyo unit on / off.
- Output A/C Displays: Digital readouts for Voltage (V) and Current (A).
- Voltage Adjustment Knobs: Fine and coarse adjustment for output voltage.
- Current Adjustment Knobs: Fine and coarse adjustment for output current limit.
- Zviteshi zvekubuda: Red (+) and Black (-) terminals for connecting loads.
- Output B-USB Section: Controls and USB ports for dedicated USB power output.
- OVP (Overvoltage Protection) Adjustment: Sets the overvoltage protection limit.
4. Setup
4.1 Kuburitsa uye Kuongorora
- Carefully remove the power supply from its packaging.
- Inspect the device for any signs of physical damage. If damage is found, do not operate the unit and contact your supplier.
- Ensure all accessories (e.g., power cord, test leads) are present.
4.2 Kuiswa
- Place the power supply on a stable, level surface.
- Ensure adequate ventilation around the unit. Do not block the air vents on the sides and rear.
- Keep the device away from direct sunlight, heat sources, and excessive dust or moisture.
4.3 Simba Connection
- Ensure the power switch on the front panel is in the "OFF" position.
- Connect the provided AC power cord to the power input socket on the rear panel.
- Plug the other end of the power cord into a suitable grounded AC power outlet (230V AC, 50Hz).
5. Operating Instructions
5.1 Basic Operation (Output A and C)
- Power On: Flip the power switch to the "ON" position. The displays will illuminate.
- Pre-setting Voltage uye Zvazvino:
- Before connecting your load, turn the voltage adjustment knobs (coarse and fine) to set the desired output voltage.
- Adjust the current adjustment knobs (coarse and fine) to set the maximum current limit. This acts as a protection mechanism for your circuit.
- Kubatanidza Mutoro: Connect the positive (+) terminal of your load to the red output terminal and the negative (-) terminal of your load to the black output terminal.
- Monitoring: The displays will show the actual output voltage and current being supplied to your load.
- Kupfuuratage Dziviriro (OVP): The OVP function protects the connected load from excessive voltage. Adjust the OVP knob to set the maximum permissible voltage. Kana zvinobuda voltage exceeds this limit, the power supply will shut down the output.
Figure 3: Connecting Test Leads
This image demonstrates how to connect test leads to the output terminals of the power supply. Red leads connect to positive terminals, and blue/black leads connect to negative terminals.
5.2 USB Output Operation (Output B-USB)
The central Output B-USB section provides dedicated USB power outputs.
- Connect your USB device to one of the USB ports (USB-B1 or USB-B2).
- Use the "MODE" and "SHOW VALUE" controls to select the desired USB output voltage (e.g., 5V, 9V, 12V) and monitor its status.
Figure 4: Adjusting Controls
A hand is shown adjusting one of the control knobs on the front panel, illustrating the user interaction with the device's settings.
5.3 Output Modes (Parallel, Series, Independent)
The VLP-2403 offers flexible output configurations for Outputs A and C:
- Independent Mode (IND): Outputs A and C operate as two separate, isolated power supplies.
- Series Mode (SER): Outputs A and C are connected in series to provide a higher voltage (up to 80V). Ensure proper wiring and voltage zvirongwa.
- Parallel Mode (PAR): Outputs A and C are connected in parallel to provide a higher current (up to 6A). Ensure proper wiring and current settings.
Refer to the front panel "MODE" switch in the Output B-USB section to select the desired configuration for Outputs A and C.
6. Kuchengeta
6.1 Kuchenesa
- Disconnect the power supply from the mains before cleaning.
