| 3 | FG (Frame Ground) |
| 4 | DC OUTPUT -V (Negative DC Output) |
| 5 | DC OUTPUT +V (Positive DC Output) |
4. Postavljanje i instalacija
Follow these steps for proper installation of the power supply.
- Montaža: Mount the power supply in a well-ventilated area. Ensure sufficient clearance around the unit for proper air convection. The unit can be mounted horizontally or vertically, but consider the airflow direction for optimal cooling. Refer to the mechanical specifications for mounting hole dimensions (Figure 3.3).
- Wiring Input (AC):
- Connect the AC Live wire to the 'L' terminal (Pin 1).
- Connect the AC Neutral wire to the 'N' terminal (Pin 2).
- Connect the Frame Ground wire to the 'FG' terminal (Pin 3). This connection is critical for safety.
- Ensure all input wires are securely fastened and have appropriate gauge for the current draw.
- Wiring Output (DC):
- Connect the positive (+) load wire to the '+V' terminal (Pin 5).
- Connect the negative (-) load wire to the '-V' terminal (Pin 4).
- Verify correct polarity before connecting to the load device.
- Ensure all output wires are securely fastened and have appropriate gauge for the current draw.
- Voltage Podešavanje: Izlazni voltage can be finely adjusted using the 'V ADJ' potentiometer located near the output terminals. Use a non-conductive screwdriver for adjustment. Nemojte prekoračiti navedeni volumentage range.
- Konačna provjera: Before applying power, double-check all wiring connections for correctness, security, and proper insulation.
5. Uputstvo za upotrebu
Once the power supply is correctly installed and wired, it is ready for operation.
- Uključeno: Apply AC power to the input terminals. The green LED indicator on the unit will illuminate, indicating that the power supply is active and providing output voltage.
- Output Voltage: The power supply will provide a stable 24V DC output. If adjustment is needed, refer to the "Voltage Adjustment" step in the Setup section.
- Učitavanje veze: Connect your DC load device to the output terminals, ensuring correct polarity.
- Nadgledanje: Observe the LED indicator. If it is off, check the input power and connections.
5.1 Derating Curve and Static Characteristics
The performance of the power supply can be affected by ambient temperature and input voltage. Refer to the following curves for optimal operation.
Figure 5.1: Derating curve showing load percentage vs. ambient temperature, and static characteristics showing load percentage u odnosu na ulazni volumentage.
- Kriva smanjenja snage: Shows the maximum permissible load at different ambient temperatures. For temperatures above 50°C, the output power must be derated to prevent overheating.
- Statičke karakteristike: Illustrates how the output load capacity is maintained across the input voltage range.
6. Održavanje
The LRS-35-24 power supply is designed for long-term reliability with minimal maintenance. However, periodic checks can help ensure optimal performance.
- čišćenje: Ensure the ventilation holes are free from dust and debris. Use a soft, dry brush or compressed air to clean the unit if necessary. Do not use liquid cleaners.
- Provjere veze: Periodically inspect all input and output wiring connections to ensure they remain secure. Loose connections can cause intermittent operation or overheating.

- Vizuelni pregled: Look for any signs of physical damage, discoloration, or unusual odors. If any issues are observed, disconnect power immediately and consult a qualified technician.
7. Otkrivanje problema
Ovaj odjeljak pruža rješenja za uobičajene probleme s kojima se možete susresti.
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Nema izlaznog voltage / LED off | Nema ulaznog naizmjeničnog napajanja Labave veze ožičenja Unutrašnja greška | Provjerite izvor naizmjeničnog napajanja i osigurač. Provjerite jesu li svi ulazni i izlazni spojevi ožičenja sigurni. If power is present and connections are good, the unit may be faulty. Contact support. |
| izlaz voltage fluctuates or is incorrect | Stanje preopterećenja Faulty load Voltage adjustment potentiometer disturbed | Reduce the load to within specifications. Disconnect the load and test the power supply independently. Carefully adjust the 'V ADJ' potentiometer to the desired voltage. |
| Unit is excessively hot | Nedovoljna ventilacija Stanje preopterećenja Visoka temperatura okoline | Ensure adequate airflow around the unit. Clear any obstructions. Reduce the load. Check the derating curve (Figure 5.1). Relocate the unit to a cooler environment if possible. |
