Overview

The connection for most conventional LED light is common anode; only quite a small number is common cathode. In order to suit LED lights with common cathode, we particularly developed this special power repeater. Its major function is to convert from common anode to common cathode, the input signal is PWM common anode signal, and the output is common cathode.

Features

  • 3 channels RGB output, 5A/CH, total 15A.
  • Accepts PWM control.
  • Input common anode signal, output common cathode, aims at driving low power common cathode LED lights, common cathode load can be expanded unlimitedly.
  • Parallel connection, unlimited numbers of units can be connected together.
  • The synchrony is not limited by whatever units connected there.
  • The in-phase cable length from controller to power repeater is maximum 500 meters.

FAQ

What does the Ltech LT-3637 do?

The LT-3637 is a LED power repeater designed to convert a PWM common anode input signal into a common cathode output. It is intended for applications where the lighting load uses common cathode operation and a standard common anode signal needs to be adapted.

Is the LT-3637 a dimming repeater or a standalone LED controller?

This model is a power repeater that works with PWM dimming signals rather than serving as a full standalone controller. Its main role is signal conversion and load expansion for compatible LED systems that require common cathode output.

What are the main electrical specs of the LT-3637?

The LT-3637 supports an input range of DC12V to DC24V. It delivers up to 180W at 12V or 360W at 24V, with a maximum load current of 5A per channel across 3 channels (15A total). These specs make it suitable for higher-load LED applications that need PWM-based signal repeating with common cathode output.

What types of LED applications is the LT-3637 best suited for?

This repeater is best suited for LED lighting setups where the load uses common cathode operation but the control side provides a PWM common anode signal. It can be a practical choice in commercial or specialty lighting systems that need that specific signal conversion.

Can the LT-3637 be used in demanding indoor or industrial environments?

The LT-3637 is specified for operation from -30°C to 55°C, which supports use across a wide temperature range. That makes it a reasonable option for indoor technical spaces and other controlled environments where temperature tolerance matters.

What warranty comes with the Ltech LT-3637?

The LT-3637 includes a 5-year warranty. For B2B buyers, that can be an important indicator of long-term support and suitability for ongoing commercial use.
