5. Įdiegimas (sąranka)
Follow these steps for proper installation of the EDR-120-24 power supply.
5.1 Montavimas
- The EDR-120-24 is designed for DIN rail mounting on TS-35/7.5 or TS-35/15 rails.
- 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.
- 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 Laidai
All connections are made via screw terminal blocks. Refer to the Terminal Pin Assignment tables in Section 4.
- 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 voltage diapazonas yra 90-264VAC arba 127-370VDC.
- Output Wiring (TB2): Connect your load to the DC OUTPUT +V and -V terminals.
- Laido tipas: Use copper wire only, rated for a minimum of 75℃.
- Sukimo momentas: Ensure terminal screws are tightened to the specified torque (Input: 6.5 Lb-in, Output: 5.5 Lb-in) to prevent loose connections.

6. Operacija
Once installed and wired correctly, the EDR-120-24 is ready for operation.
- Maitinimas: Apply the specified AC or DC input voltage.
- DC OK Indicator: A green LED labeled "DC OK" will illuminate when the output voltage yra priimtino diapazono ribose.
- Išėjimas ttage reguliavimas: Išėjimo tūristage 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 arba prieš laikrodžio rodyklę, kad sumažintumėte.
7. Priežiūra
The EDR-120-24 is designed for long-term reliability with minimal maintenance. However, periodic checks are recommended.
- Valymas: 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.
- Ryšio patikrinimai: Periodically inspect all wiring connections for tightness and signs of corrosion. Re-tighten screws if necessary after disconnecting power.
- Aplinkos stebėjimas: Užtikrinkite, kad darbo aplinka neviršytų nurodytų temperatūros ir drėgmės ribų.
8. Problemų sprendimas
If the power supply is not functioning as expected, consider the following common issues:
- No Output / DC OK LED Off:
- Check input power connections and voltage.
- Verify that the input fuse (if external) is intact.
- Check for short circuits or overloads on the output. Disconnect the load and re-test.
- Ensure the ambient temperature is within the operating range.
- Operacija su pertraukomis:
- Patikrinkite, ar nėra laisvų laidų jungčių.
- Verify that the load current does not exceed the rated output current (5A). Overload protection may be activating.
- Ensure adequate ventilation to prevent over-temperature shutdown.
- Neteisingas išvesties garsumastage:
- Adjust the "+V ADJ" potentiometer.
- Patikrinkite įvesties tūrįtage yra stabilus ir nurodytame diapazone.
If problems persist after checking these points, contact qualified service personnel or the manufacturer.
