Product Information
The Ltech LT-840-PWM10V is a high-performance signal converter designed to bridge the gap between professional DMX512 control systems and LED fixtures requiring a 10V PWM dimming signal. This robust 4-channel driver reliably translates DMX data into a smooth, flicker-free 0-100% dimming curve, making it an essential component for any dynamic light show control system. Whether you're managing temporary stage lighting or integrating multi-zone architectural displays, the LT-840-PWM10V ensures your DMX console has precise control over your 10V PWM-compatible LED strip lights. Its wide DC12-24V input range provides flexibility for various low-voltage lighting setups, delivering consistent performance for demanding applications.

Application Scenarios
How to Control & Use This Controller
- Power Input: Connect a DC12V-24V power supply to the V+ and V- input terminals. Ensure the voltage of your power supply matches the voltage required by your LED lights.
- DMX Signal Input: Wire your DMX512 master controller to the DMX signal input terminals. Ensure proper connection for DMX+, DMX-, and GND.
- PWM Output: Connect the four PWM output channels to the signal input of your 10V PWM-compatible LED lights or drivers. Observe correct polarity for all connections.
- DMX Address Configuration: Set the DMX start address on the converter, typically using DIP switches. This address determines which DMX channels from the console will control the four outputs. Consult the user manual for the specific switch settings.
- System Test: Once all connections are secure, power on the system. Use your DMX console to send commands to the configured addresses and verify that all four channels dim smoothly from 0% to 100%.
- This device is a signal converter, not a power source. You must use a separate LED power supply to power your lights.
- Always double-check that the input voltage from your power supply matches the requirements of your LED fixtures.
- Ensure all wiring is secure and correctly polarized before applying power to prevent damage to the converter and your lights.

Frequently Asked Questions
Q: What is the primary function of the LT-840-PWM10V?
A:It converts a standard DMX512 digital signal into four channels of 10V PWM (Pulse Width Modulation) analog signal. This allows you to control 10V PWM LED lights using a professional DMX console.
Q: What is the difference between this model and the LT-840-PWM5V?
A:The key difference is the output signal voltage. This LT-840-PWM10V outputs a 10V PWM signal, whereas the LT-840-PWM5V outputs a 5V PWM signal. Always choose the model that matches the signal requirement of your LED fixtures.
Q: Can this device power my LED strips directly?
A:No, this is a signal converter, not a power supply. It only provides the dimming control signal. You must connect your LED strips to a separate DC12V-24V LED power supply.
Q: Is this converter suitable for a professional light show control system?
A:Absolutely. It's designed for professional applications like stage productions and large-scale architectural lighting where reliable and precise DMX signal conversion is essential.
Q: How do I set the DMX address for this unit?
A:DMX address assignment is typically done via DIP switches located on the device. Please refer to the included user manual for detailed instructions on setting the correct starting address for the four channels.
Q: Can I use this as a replacement for a faulty DMX lighting driver?
A:Yes, it can be a key part of a replacement lighting driver solution. If your old DMX-integrated driver failed, you can pair this converter with a new, standard 10V PWM dimmable driver and power supply to restore full DMX control to your fixture.
