Frequently Asked Questions - CHLSC50 Ltech

What is the maximum LED load for the CHLSC50?

The maximum LED load is 150W. For incandescent loads, it is 250W.

Does this dimmer work with 3-way switches?

No, the CHLSC50 is a single-pole dimmer and cannot be used with 3-way switching.

How do I select leading or trailing edge mode?

The mode is selected via a small switch inside the dimmer (refer to the manual). Leading edge is for incandescent/halogen, trailing edge for LEDs.

Can I use this dimmer with a ceiling fan?

No, this dimmer is designed for lighting only. Using it with a fan can damage both the dimmer and the fan motor.

What should I do if the lights flicker?

Flickering may be due to incompatible bulbs (check they are dimmable) or insufficient load. Ensure the total LED load is at least 5W. Also, try adjusting the dimming mode switch.

Is the CHLSC50 compatible with low-voltage LED strips?

The CHLSC50 is a universal dimmer for mains voltage (120-230V). For low-voltage LED strips, you need a trailing-edge dimmer with an external driver or an LED strip specific dimmer.

How do I install the dimmer?

Turn off the circuit breaker. Connect the live wire to the 'L' terminal and the load wire to the 'Load' terminal. Neutral is required for some models (check your unit). Secure the dimmer in the wall box.

What is the minimum brightness level?

The minimum brightness depends on the bulbs used. Typically, LEDs dim down to about 5-10% of full brightness.

Can I use this dimmer outdoors?

The CHLSC50 has an IP20 rating, which is not suitable for outdoor use. Use it only indoors in dry locations.

Does the dimmer have a warranty?

Yes, Ltech provides a 2-year warranty against manufacturing defects.
