6. Postavljanje i instalacija
6.1 Spajanje ožičenja
Before connecting, ensure all power is off. Connect your DC power supply to the 'IN' terminals and your single-color LED strip to the 'OUT' terminals. Observe correct polarity (+ to + and - to -) for both input and output. The device features screw terminals for secure connections.
Image 4: Wiring diagram and DIP switch settings. This image illustrates how to connect the power supply and LED strip, and how to configure the DIP switches for PWM frequency and dimming curve.
6.2 PWM Frequency Setting
The dimmer allows selection of four PWM frequencies using DIP switches 1 and 2. Higher PWM frequencies can reduce visible flicker, which is beneficial for video recording, but may increase power noise. Refer to the table below and Image 4 for settings:
| DIP prekidač 1 | DIP prekidač 2 | Učestalost PWM-a |
|---|---|---|
| ISKLJUČENO | ISKLJUČENO | 250 Hz |
| ON | ISKLJUČENO | 500 Hz |
| ISKLJUČENO | ON | 2,000 Hz |
| ON | ON | 8,000 Hz |
6.3 Dimming Curve Setting
DIP switch 3 controls the dimming curve. A linear curve provides a direct proportional change in brightness, while a logarithmic curve offers a more natural perception of brightness change to the human eye, especially at lower dimming levels. Refer to Image 4 for settings:
| DIP prekidač 3 | Krivulja zatamnjenja |
|---|---|
| ISKLJUČENO | Linearno |
| ON | Logaritamski |
7. Upute za rad
7.1 Uključivanje/isključivanje i podešavanje svjetline
Once wired and configured, apply power to the dimmer. Rotate the knob clockwise to turn on the LED strip and increase brightness. Rotate counter-clockwise to decrease brightness and turn off the LED strip. The digital display will show the current dimming percentage.
7.2 Match Key Function
The 'MATCH' button is typically used for pairing the dimmer with a compatible wireless remote control (sold separately). Consult the remote control's manual for specific pairing instructions, which usually involve pressing the 'MATCH' button on the dimmer and a corresponding button on the remote within a short timeframe.
8. Održavanje
- Keep the dimmer clean and free from dust. Use a soft, dry cloth for cleaning.
- Ensure adequate airflow around the unit to prevent heat buildup, especially when operating at high loads.
- Do not attempt to open or modify the dimmer, as this will void the warranty and could lead to malfunction or injury.
9. Rješavanje problema
- Nema napajanja/LED diode isključene: Check all wiring connections, especially power input polarity. Ensure the power supply is functioning and providing the correct voltage. Verify the rotary knob is turned ON.
- LEDs Not Dimming: Confirm the LED strip is a single-color, dimmable type. Check wiring to the LED output terminals. Ensure the dimmer is receiving power.
- LEDs Flickering: Try adjusting the PWM frequency using DIP switches 1 and 2. A higher frequency (e.g., 8,000Hz) can often reduce visible flicker. Ensure stable power supply.
- Dimmer Gets Warm: It is normal for the dimmer to get warm during operation, especially under high load. However, if it becomes excessively hot, reduce the load or ensure better ventilation.
