5. Kurulum (Setup)

Follow these steps for proper installation of the EDR-120-24 power supply.

5.1 Montaj

  1. The EDR-120-24 is designed for DIN rail mounting on TS-35/7.5 or TS-35/15 rails.
  2. Ensure sufficient clearance for air circulation. A minimum of 5mm left and right, 40mm above, and 20mm below the power supply is recommended for optimal cooling.
  3. To mount, hook the top edge of the power supply onto the DIN rail, then push the bottom edge firmly until it clicks into place.

5.2 Kablolama

All connections are made via screw terminal blocks. Refer to the Terminal Pin Assignment tables in Section 4.

  1. Input Wiring (TB1): Connect the AC mains (L, N) or DC input (+, -) to the corresponding terminals. Ensure the Frame Ground (FG) terminal is properly connected to earth ground. The input voltagAralık 90-264VAC veya 127-370VDC'dir.
  2. Output Wiring (TB2): Connect your load to the DC OUTPUT +V and -V terminals.
  3. Tel Tipi: Use copper wire only, rated for a minimum of 75℃.
  4. Tork: Ensure terminal screws are tightened to the specified torque (Input: 6.5 Lb-in, Output: 5.5 Lb-in) to prevent loose connections.

6. Operasyon

Once installed and wired correctly, the EDR-120-24 is ready for operation.

  • Güç Açık: Apply the specified AC or DC input voltage.
  • DC OK Göstergesi: Çıkış ses seviyesi uygun olduğunda "DC OK" yazılı yeşil bir LED yanacaktır.tage kabul edilebilir aralıktadır.
  • Çıkış Hacmitage Ayarlama: çıkış hacmitage can be finely adjusted using the "+V ADJ" potentiometer located on the front panel. Use a small screwdriver to turn the potentiometer clockwise to increase voltage or counter-clockwise to decrease it.

7. Bakım

The EDR-120-24 is designed for long-term reliability with minimal maintenance. However, periodic checks are recommended.

  • Temizlik: Keep the unit clean and free from dust and debris, especially around ventilation openings, to ensure proper air convection cooling. Use a soft, dry cloth for cleaning.
  • Bağlantı Kontrolleri: Periodically inspect all wiring connections for tightness and signs of corrosion. Re-tighten screws if necessary after disconnecting power.
