Familiarize yourself with the components of your Eventek DPS-305 power supply.

4.1 Tauler frontal

The front panel features a large 4-digit LED display for voltage, current, and power readings. It includes control knobs for voltage and current adjustment, memory buttons (M1, M2, M3), an Over Current Protection (OCP) button, an Output On/Off button, a 5V/3.6A USB output port, and main output terminals (positive, negative, and ground).

4.2 Encoder Adjustment Knobs

El voltage and current adjustment knobs are precision encoder types. Pressing a knob allows you to select a specific digit on the display, which can then be adjusted by rotating the knob. This enables fine-tuning of output parameters.

4.3 High Precision Display

The backlit 4-digit LED display provides accurate readings for voltage (up to 0.01V) and current (up to 0.001A). It also automatically calculates and displays the output power in watts.

4.4 Memory Storage Function

The M1, M2, and M3 buttons allow you to save and quickly recall three sets of frequently used voltage and current settings, streamlining repetitive tasks.

4.5 USB Quick Charge Interface

A dedicated 5V/3.6A USB output port is available on the front panel for convenient charging of mobile phones or other USB-powered devices.

4.6 Característiques de seguretat

The power supply incorporates multiple safety features, including overheat protection, voltage overload protection, and short circuit protection. In the event of a short circuit, a buzzer alarm will sound, and the output will automatically stop to protect the unit and the connected load.

5. Configuració

1. Col·locació: Place the power supply on a stable, level surface with adequate ventilation. Ensure no objects obstruct the air vents on the sides and rear of the unit.

3. Encesa inicial: Flip the power switch located on the rear of the unit to the "ON" position. The display will illuminate.
4. Cables de sortida: Connect the banana plug test leads to the output terminals on the front panel. The red lead connects to the positive (+) terminal, and the black lead connects to the negative (-) terminal. The green terminal is for ground.

6. Instruccions de funcionament

6.1 Configuració Voltage i Actual

1. Turn Off Output: Ensure the output is off by pressing the SORTIDA button. The output indicator will be off.
2. Ajust Voltage:
   • Premeu el botó VOLTAGE knob to select the digit you wish to adjust (the selected digit will blink).

   • Repeat until the desired voltage s'estableix.
3. Ajusta el corrent:
   • Premeu el botó ACTUAL knob to select the digit you wish to adjust.
   • Gira el ACTUAL botó per canviar el valor del dígit seleccionat.
   • Repeat until the desired current limit is set.
4. Habilita la sortida: Una vegada voltage and current limits are set, connect your load to the output terminals. Press the SORTIDA button to enable the output. The output indicator will light up.

6.2 Using Memory Functions (M1, M2, M3)

1. Desar la configuració:
   • Establiu el volum desitjattage i el corrent utilitzant els botons respectius.
   • Premeu i manteniu premut un dels botons de memòria (M1, M2, o M3) for approximately 3 seconds until a beep sounds or the display indicates saving. The current settings are now stored.
2. Recalling Settings:
   • Briefly press the desired memory button (M1, M2, o M3). The stored voltage and current values will be loaded onto the display.
   • Remember to press the SORTIDA button to enable the output with the recalled settings.

6.3 Protecció contra sobreintensitat (OCP)

The OCP function protects the connected load from excessive current. When OCP is enabled and the output current exceeds the set limit, the power supply will automatically cut off the output and sound an alarm.

• Enable/Disable OCP: Premeu el botó OCP button to toggle the Over Current Protection function on or off. An indicator on the display will show its status.
• Adjust OCP Limit: The OCP limit is typically set by the current limit knob. Ensure your current limit is set appropriately for your application.
