In the field of LED lighting, Triac (Thyristor) dimming technology is highly favored for its wide compatibility and smooth dimming effects. For customers using DC24V or DC12V LED strips, choosing a high-performance Triac constant voltage power supply is crucial. This article will detail the features, advantages, and applications of Triac constant voltage power supplies, helping you find the perfect power supply and LED strip combination.
What is a Triac Constant Voltage Power Supply?
A Triac constant voltage power supply is a dimming power supply designed specifically for LED strips. It supports Triac dimming and provides a constant DC output voltage (such as DC24V or DC12V). It seamlessly integrates with common Triac dimmers to achieve smooth brightness adjustment for LED strips while ensuring stable voltage output, avoiding flickering or voltage fluctuations.
Why Choose a Triac Constant Voltage Power Supply?
1. Compatibility with Existing Dimming Systems
Many buildings and homes already have Triac dimmers installed for traditional lighting (e.g., incandescent or halogen lights). A Triac constant voltage power supply allows customers to upgrade to LED lighting without replacing their existing dimming systems.
2. Cost-Effectiveness
Triac constant voltage power supplies are generally more affordable than dedicated LED controllers, making them a budget-friendly choice for both small and large projects. They simplify installation by directly replacing traditional power supplies, reducing additional wiring and setup costs.
3. Smooth Dimming Experience
High-quality Triac constant voltage power supplies offer flicker-free dimming, providing a smooth and comfortable lighting experience. They support a wide dimming range (0-100%), ensuring precise control over brightness levels.
4. Ideal for Constant Voltage LED Strips
Most LED strips (especially DC12V and DC24V) are designed for constant voltage operation. Triac constant voltage power supplies ensure stable and uniform brightness, avoiding issues like flickering or uneven lighting.

How to Choose the Right Triac Constant Voltage Power Supply?
1. Determine LED Strip Voltage: Choose a power supply that matches the voltage of your LED strip (e.g., DC24V or DC12V).
2. Calculate Total Power: Ensure the power supply’s maximum output power exceeds the total power of your LED strip.
3. Select Dimming Method: Choose a compatible dimming interface (Triac, 0-10V, etc.) based on your dimmer type.
4. Consider Installation Environment: Select an appropriate waterproof rating (e.g., IP42) and heat dissipation design.
