| 5 | DC OUTPUT +V (Positive DC Output) |
4. الإعداد والتثبيت
Follow these steps for proper installation of the power supply.
- التركيب: 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).
- مدخل الأسلاك (تيار متردد):
- 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.
- مخرج الأسلاك (تيار مستمر):
- 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.
- المجلدtagالتعديل ه: الناتج المجلدtage can be finely adjusted using the 'V ADJ' potentiometer located near the output terminals. Use a non-conductive screwdriver for adjustment. لا تتجاوز الحجم المحددtagالنطاق ه.
- التحقق النهائي: Before applying power, double-check all wiring connections for correctness, security, and proper insulation.
5. تعليمات التشغيل
Once the power supply is correctly installed and wired, it is ready for operation.
- تشغيل الطاقة: 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.
- حجم الإخراجtage: The power supply will provide a stable 24V DC output. If adjustment is needed, refer to the "Voltage Adjustment" step in the Setup section.
- اتصال التحميل: Connect your DC load device to the output terminals, ensuring correct polarity.
- يراقب: 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 مقابل حجم الإدخالtage.
- منحنى تخفيض التصنيف: Shows the maximum permissible load at different ambient temperatures. For temperatures above 50°C, the output power must be derated to prevent overheating.
