BC-331-DIN 0/1-10V DIN Rail Dimming Driver Overview
The BC-331-DIN is a 0/1-10V to PWM dimming driver built on a DIN rail housing. It solves a problem that comes up constantly in retrofits: 0/1-10V is the standard control signal left behind by fluorescent dimming systems, while LED strips need PWM. This driver converts one to the other, so a building’s existing 0/1-10V wiring can drive modern constant voltage LED without replacing the control infrastructure.
It can dim fluorescent and LED fixtures at the same time, which is exactly what you need during a staged retrofit where old and new luminaires share a circuit. One channel delivers up to 18A, or roughly 216W at 12V and 432W at 24V, and the input automatically adapts anywhere across DC12V to DC24V.
The DIN rail form factor is the point of this particular model. Where the standard BC-331 units are loose modules, the DIN version clips straight onto a rail inside a distribution board or control cabinet — which is why it suits large-scale projects where many channels are wired into one enclosure.

Which BC-331 Do You Need?
The BC-331 series covers the same 0/1-10V to PWM conversion in several housings and current ratings. Choose by how much current the channel has to carry, then by where the unit will live.
| Model | Rating | Best For |
|---|---|---|
| BC‑331‑DIN (this model) | 18A, DIN rail | Distribution boards and control cabinets on large projects |
| BC‑331‑16A | 16A | Higher current runs in a standard housing |
| BC‑331‑10A | 10A | Mid size single colour runs |
| BC‑331‑6A | 6A | Smaller runs and tighter budgets |
| BC‑331‑WP | Waterproof | Damp or outdoor locations |
| BC‑331‑CC | Constant current | Constant current LED loads, not constant voltage strip |
Size the driver to roughly 1.2 times the LED load current, then pick the housing — DIN rail for cabinet installs, WP for wet areas, standard for everything else. If the load is constant current rather than constant voltage, use the CC version.
Installation Notes
This driver must be used with a DC constant voltage power supply, and the supply voltage must match the driver’s input range. Mount it in a well ventilated spot, keep wiring correct and firm to avoid short circuits, and never connect cables with the power on. Multiple units can be run together, or you can add power repeaters to extend how much lighting one control channel can drive.
