2. Безбедносне информације

Молимо вас да прочитате и разумете сва безбедносна упутства пре коришћења уређаја како бисте спречили повреде или оштећења.

  • електрична безбедност: Always connect the power supply to a grounded outlet. Do not operate in wet conditions. Ensure the power cord is undamaged.
  • вентилација: Ensure adequate ventilation around the unit. Do not block the cooling fan or vents.
  • Заштита од преоптерећења: The unit features short-circuit protection and overload protection (Constant Current/Constant Voltage mode) to safeguard the device and connected circuits. A buzzer provides audible feedback during protection events.
  • Управљање температуром: Active temperature management helps maintain optimal operating conditions.
  • Унутрашње компоненте: Do not attempt to open or service the unit. Refer all servicing to qualified personnel.

4. Подешавање

  1. Распакивање: Пажљиво извадите напајање и сву додатну опрему из паковања. Проверите да ли има знакова оштећења.
  2. Пласман: Place the unit on a stable, level surface, ensuring sufficient space for ventilation, especially around the rear cooling fan.
  3. Прикључак за напајање: Connect the provided power cord to the power input on the rear of the unit, then plug it into a grounded 230V AC outlet.
  4. Веза тестног кабла: Connect the 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.

5. Упутство за употребу

5.1. Укључивање/искључивање

To power on the unit, flip the power switch located on the rear panel to the 'ON' position. The digital display will illuminate. To power off, flip the switch to the 'OFF' position.

5.2. Подешавање јачине звукаtagе и струја

The YIHUA 3005D-III uses digital encoder knobs for precise adjustment of voltage and current. These eliminate the need for separate coarse and fine adjustment dials.

  • Волtagе Подешавање: Користите дугме „Јачина звука“TAGE' дугме за подешавање жељене јачине звукаtage. Turning the knob slowly adjusts in small increments (1 unit per click), while turning it quickly allows for larger increments.
  • Тренутно подешавање: Use the 'CURRENT' knob to set the desired output current limit. Similar to voltage, slow turns provide fine adjustment, and quick turns provide coarse adjustment.

5.3. Константна запреминаtage (CV) and Constant Current (CC) Modes

Напајање се аутоматски пребацује између константне јачине звукаtage (CV) and Constant Current (CC) modes based on the load characteristics.

  • Цонстант Волtagе (CV) режим: Indicated by a green LED. In this mode, the output voltage remains constant at the set value, and the current varies according to the load.
  • Режим константне струје (CC): Indicated by a red LED. In this mode, the output current remains constant at the set limit, and the voltage varies according to the load. This mode activates when the load resistance is too low for the set voltage, causing the current to reach its preset limit.

6. Одржавање

  • Чишћење: Искључите напајање из мреже пре чишћења. Користите меку, суву крпу за брисање спољашњости. Не користите абразивна средства за чишћење или раствараче.
  • вентилација: Periodically check that the cooling fan and vents are free from dust and obstructions.
  • Складиштење: Када се уређај не користи дуже време, чувајте га на сувом и месту без прашине.
