3.2 การเชื่อมต่อทางไฟฟ้า

Connect the driver according to the wiring diagram. Ensure correct polarity for DC output and proper AC input connections.

• อินพุตไฟฟ้ากระแสสลับ: Connect the AC Live (L), Neutral (N), and Ground (FG) wires to the corresponding terminals on the driver.
• เอาต์พุต DC: Connect the LED fixture to the V+ (positive) and V- (negative) output terminals.
• Dimming (B-Type): For dimmable models (HLG-240H-24B), connect the DIM+ and DIM- wires to your dimming control system.

4. คู่มือการใช้งาน

The HLG-240H-24B operates in both Constant Voltage (CV) and Constant Current (CC) modes, providing flexibility for various LED applications. The dimming function allows for adjustable light output.

4.1 Driving Methods of LED Module

This series is capable of operating in either Constant Current mode (direct drive) or Constant Voltage mode (using additional DC/DC drivers). The highest voltage at the output depends on the configuration of the end system. For compatibility issues, consult MEAN WELL.

Figure 4: Top part shows the internal block diagram of the HLG-240H series LED driver, illustrating the flow from EMI filter to output. The bottom part displays a graph of typical output current normalized by rated current, indicating Constant Voltage area, Constant Current area, and Overload Protection.

4.2 Dimming Operation (B-Type)

The HLG-240H-24B (B-Type) supports 3-in-1 dimming functions: 1-10VDC, 10V PWM signal, or resistance. Output constant current level can be adjusted by applying one of these methodologies between DIM+ and DIM-.

• Applying Additive 1-10VDC: Connect a 1-10VDC signal between DIM+ and DIM-.
• Applying Additive 10V PWM Signal: Connect a 10V PWM signal (frequency range 100Hz ~ 3KHz) between DIM+ and DIM-.
• Applying Additive Resistance: Connect a variable resistance between DIM+ and DIM-.

Note: Dimming source current from power supply is 100µA (typ.). Connecting DIM- to -V is not recommended.

Each method is accompanied by a graph showing the relationship between the dimming input and the output current percentage.

5. การบำรุงรักษา

The HLG-240H-24B LED driver is designed for long-term reliability with minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.

• การทำความสะอาด: Keep the driver free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
