FOUR PWM FREQUENCY SETTINGS: Match the dimmer switches for led lights to your load, 8KHZ(10A), 4KHZ(15A), 2KHZ(20A), 800HZ(30A). Maximum current changes with frequency, do not exceed the rating for theselected mode
SMOOTH 0-100% KNOB DIMMING: Fine-tune a compatible single-color LED strip from low light to full Ibrightness. PWM LED dimmer switch provides gradual responsive adjustment for cabinet, display, workbench, RV and prottected vehicle-interior lighting
HIGHER-FREQUENCY CONTROL: Choosing a higher PWM frequency can help reduce flickering in compatible devices. For example, when using a camera device, choosing the high-frequency 8KHZ (10A) grade will significantly reduce the occurrence of stripes on the camera. The final effect may vary depending on the LED light strip, power supply, frame rate, etc
FOR DC 5-24V SINGLE-COLOR LED: Works with 2 pin, constant-voltage COB/SMD single-color 5050,2835 and 5630 LED strips. Input voltage must match the LED strip voltage; this controller does not step voltage uppor down
CHECK COMPATIBILITY BEFORE ORDERING: Not for 120VAC, RGB, RGBW, CCT, addressable LED, 0-10V systems, fans or motors. This DC 5-24V PWM LED dimmer switch is 88 x 52 x 30 mm. The metal housing is intended for dry, protected locations and is not waterproof. Power supply and LED strip are not included

Is this a 120V household wall dimmer?
No. It is a low-voltage DC PWM LED Dimmer Switch for 5V, 12V or 24V single-color LED systems. Not suitable for multi-color mixed LED lamps, 120V AC, RGB, RGBW, CCT, or addressable LED.
Does it convert 24V to 12V?
No. The input must be equal to the output.Output voltage follows input voltage. Use a power supply that matches the LED strip.
Does 30A apply at every frequency?
No. The rated limits are 30A at 800Hz, 20A at 2kHz, 15A at 4kHz and 10A at 8kHz. Select the correct frequency according to your LED load and application before use.
How should the LED dimmer be connected?
Connect DC power to INPUT terminals and single-color LED to OUTPUT terminals. Match positive and negative polarity. Cut power before wiring, fasten screws and test under low load first.
Is this LED dimmer waterproof, and can it be used outdoors?
No. The DC 5-24V PWM LED Dimmer is intended for dry, protected locations and should not be exposed directly to rain, moisture or water. For outdoor, boat or vehicle applications, install it inside a dry, ventilated and weather-protected enclosure.
