5.1. Setting Voltage жана Current

The MDC01 features digital control technology for precise adjustment of voltage жана ток.

1. Coarse and Fine Adjustment: Voltage and Current adjusting knobs allow for both coarse and fine adjustments. Press the respective knob once to toggle between coarse (adjusting whole numbers) and fine (adjusting decimal places) adjustment modes. Rotate the knob to change the value.
2. Setting Voltage: Көлөмдү айландырууtage adjusting knob to set the desired output voltage. The 4-digit LED display will show the set value.
3. Учурдагы чектөөнү коюу: Rotate the Current adjusting knob to set the maximum output current (current limit). This protects your load from excessive current. The 4-digit LED display will show the set value.

5.2. Constant Voltage (CV) and Constant Current (CC) Mode

Кубат булагы автоматтык түрдө туруктуу volt ортосунда которулатtage (CV) and Constant Current (CC) modes depending on the load and the set current limit.

• Constant Voltage (CV): When the load resistance is high, the output current is below the set current limit. The power supply maintains the set output voltage, and the CV indicator will be illuminated.
• Туруктуу ток (CC): When the load resistance is low, causing the current to reach the set current limit, the power supply automatically switches to CC mode. It will then maintain the set current, and the output voltage will drop. The CC indicator will be illuminated. This protects the load from overcurrent.

5.3. Маалыматты кармоо функциясы

The MDC01 includes a data hold function to temporarily store a set of voltage жана учурдагы маанилер.

• To activate Data Hold: Press both the Voltage and Current adjusting knobs simultaneously for 3 seconds. The display will indicate that the values are held.
• To release Data Hold: Press both knobs simultaneously again for 3 seconds.

5.4. Чыгууну башкаруу

Use the 'Output' button on the front panel to enable or disable the power output to your load. This allows you to set voltage and current parameters without immediately applying power to your circuit.

6. Техникалык тейлөө

Туура техникалык тейлөө электр менен камсыздооңуздун узак мөөнөттүү жана ишенимдүү иштешин камсыз кылат.

• Тазалоо: Тазалоодон мурун электр кубатын электр тармагынан ажыратыңыз. Сыртын сүртүү үчүн жумшак, кургак чүпүрөктү колдонуңуз. Абразивдүү тазалоочу каражаттарды же эриткичтерди колдонбоңуз.
• Вентиляция: Regularly check that the cooling fan and ventilation openings are free from dust and obstructions. A built-in fan reduces operational noise and prolongs product life.
• Сактагычты алмаштыруу: If the unit fails to power on, the fuse may need replacement. The fuse box is located on the rear panel. Disconnect the power cord, open the fuse box, and replace the fuse with one of the same type and rating (5A, 110V AC).

  • Check if the rear power switch is ON.
  • Verify the AC power cord is securely connected to both the unit and the wall outlet.
  • Check the fuse in the rear fuse box and replace if blown (refer to Maintenance section).
• No Output Voltage/Current:
  • Ensure the front panel 'Output' button is pressed (indicator light ON).
  • тtage and current limit settings are not set to zero.
  • Check for short circuits in your load. The power supply may be in CC mode with very low voltage output if a short is present.
  • Ensure the load is correctly connected to the output terminals.
• Туура эмес окуулар:
  • Compare readings with a calibrated multimeter. Small discrepancies may occur due to display resolution.
  • Ensure proper connection of test leads to the load and power supply.
• Ашыкча ысып кетүү:
  • Ensure the cooling fan and vents are not obstructed.
  • Reduce the load or operating time if the unit frequently triggers thermal protection.
