6.1 יקערדיק אָפּעראַציע

Once properly installed and connected, the ELG-75-C700 will provide a constant current output to the connected LED load. Ensure the LED load's voltage requirements fall within the power supply's constant current region (53~107V for C700 model).

6.2 Output Current Adjustment (A-Type)

For A-Type models, the constant current level can be adjusted via an internal potentiometer. This allows fine-tuning of the output current within the specified adjustment range (350~700mA for C700 A-Type).

6.3 Dimming Operation (B-Type)

B-Type models feature a 3-in-1 dimming function, allowing adjustment of the output current via 0~10VDC, PWM signal, or resistance. The dimming wires are typically DIM+ (Blue) and DIM- (White).

• 0~10VDC Dimming: Connect a 0~10VDC dimmer to the DIM+ and DIM- terminals. 0V typically corresponds to 0% output, and 10V to 100% output.
• PWM Signal Dimming: Connect a PWM signal source to the DIM+ and DIM- terminals. The frequency range for PWM dimming is typically 100Hz ~ 3KHz.
• Resistance Dimming: Connect a variable resistor (potentiometer) between DIM+ and DIM-. The resistance value will determine the output current level.

Caution: Do not connect "DIM-" to "-V" (output negative terminal).
