| 2 | AC/N (Neutral AC Input) |
| 3 | FG (Темја на рамка) |
| 4 | DC OUTPUT -V (Negative DC Output) |
| 5 | DC OUTPUT +V (Positive DC Output) |
4. Поставување и инсталација
Follow these steps for proper installation of the power supply.
- Монтирање: 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.
- Voltagд Прилагодување: Излезот волtage can be finely adjusted using the 'V ADJ' potentiometer located near the output terminals. Use a non-conductive screwdriver for adjustment. Не надминувајте го наведениот волtagд опсег.
- Конечна проверка: Before applying power, double-check all wiring connections for correctness, security, and proper insulation.
5. Упатства за работа
Once the power supply is correctly installed and wired, it is ready for operation.
- Вклучување: 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.
- Излез 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.
- Вчитај врска: Connect your DC load device to the output terminals, ensuring correct polarity.
- Следење: 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 vs. input voltage.
- Дертирачка крива: Shows the maximum permissible load at different ambient temperatures. For temperatures above 50°C, the output power must be derated to prevent overheating.
- Статични карактеристики: Illustrates how the output load capacity is maintained across the input voltagд опсег.
6. Одржување
The LRS-35-24 power supply is designed for long-term reliability with minimal maintenance. However, periodic checks can help ensure optimal performance.
- Чистење: 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.
- Проверки за поврзување: Periodically inspect all input and output wiring connections to ensure they remain secure. Loose connections can cause intermittent operation or overheating.

Овој дел нуди решенија за вообичаени проблеми со кои може да се соочите.
| Проблем | Можна причина | Решение |
|---|---|---|
| Нема излез волtage / LED диодата е исклучена | Нема влезно напојување со наизменична струја Лабави приклучоци за жици Внатрешна грешка | Проверете го изворот на наизменична струја и прекинувачот. Проверете дали сите влезни и излезни жици се безбедни. If power is present and connections are good, the unit may be faulty. Contact support. |
| Излез волtage варира или е неточно | Состојба на преоптоварување 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 | Недоволна вентилација Состојба на преоптоварување Висока температура на околината | 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. |
| Audible noise from unit | Normal operation (slight hum) Overload or fault condition | A slight hum can be normal. If noise is loud or unusual, check for overload. Disconnect power and contact support if noise persists and is concerning. |
