About this item
- 【Compatible Strips】CH21RF 2in1 LED Controller is suitable for PWM without IC single Color and CCT LED strips. With a maximum PWM dimming frequency of 20 kHz, it effectively reduces noise and fickering during operation. Working voltage: DC12V/DC24V. The choice of power supply depends on the LED strip. If your LED light is DC12V, please use DC12V power supply. Output: 7.5A/Channel(Total output Max:12A/20kHz 15A/2kHz).
- 【3 Types of Control】The CH21RF controller requires a compatible RF remote and a Tuya gateway to function(both sold separately) . Supports 2.4GHz RF remotes (e.g., RC01RFB, RC02RFB, WR02RF). With Tuya GW01W Wi-Fi Gateway, use Tuya/Smart Life App for remote control: timer, scenes, tap-to-run, countdowns, music mode. Voice control via Alexa & Google Home is also supported through the gateway for turning lights on/off, adjusting brightness, or changing colors.
- 【Auto-transmitting Synchronization function】One controller can transmit the signal from the remote control to the another controller within 99ft(30 meters). As long as there is a LED strip controller within 99ft(30 meters), the remote control distance can be limitless.Auto-Synchronization Function.Different controllers can work synchronously when they are started at different times, controlled by the same remote control at the same dynamic mode and with the same speed.
- 【Smart Timer & Memory Protection】Schedule up to 5 daily timers to automatically turn lights on/off at fixed times. Built-in power-off memory instantly saves custom colors, brightness, and effects – restoring them automatically after power loss. Control lights up to 30m away (open areas) and group up to 5 controller zones for seamless whole-home lighting synchronization.
- 【Switching Output Mode】The controller supports switchable output modes between single color/dual color and PWM high-frequency/low-frequency. Default mode is CCT mode. Short-press the "SET" button to toggle color modes: the pilot lamp flickers white for single-color mode or yellow for CCT mode. To switch PWM frequency, press and hold "SET" for >15 seconds: the blue indicator flickers slowly for low frequency (2kHz), or the green indicator for high frequency (20kHz).

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
