Product Information
The Ltech LT-484S is a professional-grade dimming signal converter designed to bridge the gap between modern digital lighting control systems and traditional analog or PWM drivers. This versatile device expertly translates incoming DALI or PUSH DIM signals into four channels of clean, stable 0-10V, 5V PWM, or 10V PWM output. It's the ideal solution for retrofitting commercial spaces or integrating various fixture types into a unified control scheme.
By accepting a universal 100-240Vac input, the LT-484S simplifies installation, connecting directly to mains power. Its 4-channel output provides the flexibility to manage multiple lighting zones from a single compact unit, enabling precise, flicker-free dimming from a subtle 0.1% to full brightness. Whether you're upgrading an office with a sophisticated DALI system or using a simple momentary switch for PUSH DIM control, the LT-484S ensures seamless compatibility and reliable performance.

Application Scenarios
How to Control & Use This Controller
- Ensure mains power is off before beginning installation.
- Connect the 100-240Vac line (L) and neutral (N) wires to the AC input terminals.
- For DALI control, connect the DALI bus wires to the DA1 and DA2 input terminals. Polarity is not critical for DALI.
- For PUSH DIM control, connect a normally open momentary switch to the PUSH terminals.
- Connect the 4-channel signal outputs (CH1-CH4) to the corresponding signal inputs on your 0-10V or PWM dimmable LED drivers.
- The default output is 0-10V. To select 5V or 10V PWM output, consult the detailed product manual for configuration instructions.
- Once all wiring is secure, restore power and test the dimming functionality using your DALI controller or PUSH DIM switch.
- This device is a signal converter, not a power supply. It does not provide power to LED lights directly.
- Always ensure the output signal type (0-10V, 5V PWM, 10V PWM) matches the input requirements of your connected LED drivers.

Frequently Asked Questions
Q: What is the main purpose of the LT-484S converter?
A:It translates modern digital DALI signals or simple PUSH DIM inputs into analog 0-10V or PWM signals, allowing new control systems to work with older or different types of LED drivers.
Q: Can I control four different groups of lights independently?
A:Yes, this unit features four independent output channels, enabling you to control four separate lighting zones or fixtures from a single converter.
Q: Does this converter power my LED strips?
A:No, it is a low-current signal converter. You must connect its outputs to the signal inputs of compatible dimmable LED drivers, which in turn power your LED strips or fixtures.
Q: What is the difference between the DALI and PUSH DIM inputs?
A:DALI is a digital protocol used in complex, addressable lighting networks for precise control. PUSH DIM is a much simpler method that uses a standard momentary (push-to-make) switch for basic dimming.
Q: How do I choose between 0-10V, 5V PWM, and 10V PWM output?
A:The choice depends entirely on the input requirements of your LED drivers. Check your driver's specifications and configure the LT-484S to match. The default setting is 0-10V.
Q: What power source does the LT-484S itself need?
A:The converter connects directly to your building's main electrical supply, accepting a universal voltage of 100-240Vac.
Q: Where can I learn more about DALI and 0-10V dimming?
A:For an in-depth explanation of these technologies, please read our articles on 'What Is DALI Dimming?' and 'Things You Need to Know About 0-10V Dimmer & Dimming'.
