3. Installation og opsætning

The HLG-240H-24B driver is designed for easy installation. Follow these steps for proper setup:

3.1 Mekanisk installation

Mount the driver securely in a location that allows for adequate airflow and is protected from excessive heat or direct sunlight. Refer to the mechanical specifications for dimensions and mounting hole details.

3.2 Elektriske forbindelser

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

• AC-indgang: Connect the AC Live (L), Neutral (N), and Ground (FG) wires to the corresponding terminals on the driver.
• DC-udgang: 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. Betjeningsvejledning

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.

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. Vedligeholdelse

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.

• Rensning: Keep the driver free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• Tilslutningstjek: Kontrollér regelmæssigt alle elektriske forbindelser for at sikre, at de er sikre og fri for korrosion.
• Miljøovervågning: Sørg for, at driftsmiljøet holder sig inden for de angivne temperatur- og fugtighedsgrænser.
• Ventilation: Kontroller, at ventilationsåbningerne ikke er blokerede.

• LEDs Flickering or Dim:
  • Check output connections for loose wires or incorrect polarity.
  • Verify dimming signal (if applicable) is stable and within range.
  • Ensure the driver is not overheating; check ventilation.
• Overophedning af føreren:
  • Sørg for tilstrækkelig luftgennemstrømning omkring enheden.
  • Kontroller, at omgivelsestemperaturen er inden for det angivne driftsområde.
  • Check if the load exceeds the driver's maximum power rating.
• Beskyttelsesfunktioner: The HLG-240H series includes built-in protections:
  • Overstrømsbeskyttelse: Recovers automatically after fault condition is removed.
  • Kortslutningsbeskyttelse: Hikketilstand, gendannes automatisk efter at fejltilstanden er fjernet.
