5. Návod k obsluze

This section details the operation of the MATRIX MPS-3005H-3, including setting voltage and current, and utilizing its various output modes.

5.1 Nastavení Voltage a proud

1. Ensure the output switches for CH1 and CH2 are in the OFF position.
2. Use the respective voltage adjustment knobs for CH1 and CH2 to set the desired output voltage. Rotate clockwise to increase, counter-clockwise to decrease.
3. Use the respective current adjustment knobs for CH1 and CH2 to set the desired output current limit.
4. Press the output switch for the desired channel (CH1 or CH2) to enable the output. The corresponding indicator light will illuminate.

Figure 5.1: The coded switch knobs allow for quick and easy push-in adjustments, facilitating both fine and coarse tuning of voltage a aktuální.

5.2 Převtage Protection (OVP) and Overcurrent Protection (OCP) Setting

To set OVP and OCP limits:

1. Dlouze stiskněte objtage adjustment knob (for OVP) or current adjustment knob (for OCP) for the desired channel. The display will show "OFF" or the current setting.
2. Rotate the knob to set the desired OVP or OCP value.
3. Short press the knob to exit the setting mode.

5.3 Series and Parallel Modes

The power supply supports series and parallel operation for increased voltage nebo proudový výstup.

1. Sériový režim: Press the multifunction button on the left side of the front panel until "SE" (Series) is displayed. In this mode, connect the positive terminal of CH1 to the negative terminal of CH2 using a short lead. The total voltage bude součet objemových objemů CH1 a CH2tages, while the current remains the current of the master channel.
2. Paralelní režim: Press the multifunction button until "PA" (Parallel) is displayed. In this mode, connect the positive terminals of CH1 and CH2 together, and the negative terminals of CH1 and CH2 together. The total current will be the sum of CH1 and CH2 currents, while the voltage remains the voltage of the master channel.

5.4 Fixed 5V/3A Output (CH3)

The CH3 output provides a fixed 5V/3A supply, suitable for powering standard 5V devices. This output is always active when the unit is powered on and does not have independent controls.

6. Údržba

Správná údržba zajistí dlouhou životnost a spolehlivý provoz vašeho zdroje napájení.

• Čištění: K čištění vnější strany jednotky používejte měkký, suchý hadřík. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
• Větrání: Regularly check that the air vents and the intelligent temperature control fan are free from dust and obstructions.
• Skladování: When not in use for extended periods, store the power supply in a cool, dry environment, away from direct sunlight and excessive dust.
