0‑10V vs 1‑10V Dimming Module: Wrong Choice Ruins Your Brightness Control
Installed smart lights but get choppy dimming? Lights still bright even at minimum setting? Or flickering issues? You have probably picked the wrong dimming module! What exactly are the differences among 0‑10V, 1‑10V and PWM?
1. Why Do We Need Dimming Modules?
Regular switches: Lights only have ON / OFF status
Dimming module: Supports stepless brightness adjustment from 0%‑100%
Benefits of dimming:
- Movie night: Dim lights for immersive atmosphere
- Dinner time: Warm light at 60% for coziness
- Bedtime: Gradually dim down to 10% for natural sleep
2. Core Differences: 0‑10V vs 1‑10V
| Comparison Item | 0‑10V | 1‑10V |
|---|---|---|
| Voltage Range | 0V‑10V | 1V‑10V |
| Minimum Brightness | Full light‑off | ~10% minimum brightness |
| Dimming Curve | Linear | Logarithmic (human‑eye friendly) |
| Application Scenario | Scenarios requiring complete light‑off | General lighting dimming |
| Fixture Compatibility | Requires special LED drivers | Supported by most LED drivers |
Pick 0‑10V if full light‑off is required. Pick 1‑10V for brightness adjustment only (more widely used).
3. Module Selection Guide to Avoid Pitfalls
1‑10V Dimming Module (Most Common)
| Model | Channels | Application Scenario |
|---|---|---|
| MTN647091 | 1‑channel | Single‑zone dimming / Bedroom |
| MTN646991 | 3‑channel | Living‑room / Dining‑room zoning dimming |
| MTN6720‑0004 | 4‑channel | Multi‑zone centralized control |
| MTN6720‑0008 | 8‑channel | Commercial spaces / Large‑size residences |
0‑10V Dimming Module
| Model | Channels | Power Rating | Application Scenario |
|---|---|---|---|
| MTN6710‑0102S | 2‑channel | 350W per channel | Scenarios requiring complete light‑off |
| MTN6810‑0102 | 2‑channel | 350W per channel | Expansion module |
4. Dimming Module Wiring Tips
1‑10V Wiring: Dimming Module ──(+10V)──→ LED Driver Dimming Module ──(0V)────→ LED Driver Dimming Module ──(Dimming Signal)→ LED Driver
Notes:
- Use shielded cable for dimming signal wire to prevent interference
- Max cable length: 100 meters
- Confirm your LED driver supports the matching dimming protocol
5. FAQ
Q: Can 1‑10V turn lights completely off? A: No. Minimum brightness stays around 10%. Use a switching module for full cut‑off.
Q: How to fix flickering during dimming? A: Check three points:
- Whether the LED driver supports dimming
- Correct wiring connections
- Avoid overloading the module
Q: How many lights can one module drive? A: Depends on power rating. For a 350 W module with 10 W lamps, maximum 35 units. Keep 20% power margin for safety.
