Frequently Asked Questions - CHLSC30TX Ltech

How do I install the Ltech CHLSC30TX dimmer?

Connect the DC power supply to the input terminals (V+ and V-), then connect the LED load to the output terminals. Ensure the total load does not exceed 72W. Use a suitable junction box for safety.

Can I use this dimmer with any LED strip?

This dimmer is designed for constant voltage LED strips (12V or 24V). It is not compatible with constant current LEDs or mains voltage bulbs.

What is the minimum load required?

The minimum load is approximately 1W (at 12V) to ensure smooth dimming. Below this, the dimmer may not function correctly.

Does the dimmer emit noise?

The dimmer uses PWM at a frequency above audible range (typically >1kHz), so it is silent during operation.

How do I adjust the brightness?

Turn the rotary knob clockwise to increase brightness, counterclockwise to decrease. Press the knob to switch ON/OFF.

Is the dimmer suitable for outdoor use?

No, the IP20 rating means it is only for indoor, dry locations. Keep away from moisture.

What should I do if the dimmer gets hot?

Ensure proper ventilation and that the load does not exceed the rated 72W. If overheating persists, reduce load or check connections.

Can I use multiple dimmers in parallel?

No, multiple dimmers should not be connected in parallel to control the same load. Use one dimmer per circuit.

How do I clean the dimmer?

Disconnect power, then wipe the casing with a soft, dry cloth. Do not use water or solvents.

What is the warranty period?

Ltech offers a 2-year warranty against manufacturing defects. Keep your purchase receipt.
