Direct mains-voltage dimming: Controls AC loads such as incandescent, halogen, dimmable LED lamps, LED drivers, fluorescent ballasts, and motorized effects directly from 110V / 120V / 220V / 230V / 240V AC — no low-voltage DC driver required.
DMX512 control: Complies with standard DMX512 / DMX512(1990); addressable from DMX start address 001–512 via DIP switch, digital display, buttons, or RDM.
RDM ready (optional): Remote Device Management support allows the console to discover the dimmer, read status, change dimming curve, set min/max level, and configure address remotely.
Phase-cut dimming technology:
Leading-edge / forward-phase (TRIAC / thyristor) — best for incandescent and halogen loads.
Trailing-edge / reverse-phase (transistor / MOSFET / IGBT) — better for dimmable LED lamps and electronic transformers.
Some models support sine-wave dimming for flicker-free, noise-free theatrical-grade performance.
Smooth 0–100% dimming: 8-bit (256 levels), 12-bit (4096 levels), or 16-bit (65536 levels) resolution depending on model; selectable dimming curves: linear, square, S-curve, logarithmic.
Multi-channel dimmer pack: 1CH / 2CH / 3CH / 4CH / 6CH / 12CH / 24CH versions; each channel independently addressable and can be set as dimmer or relay/switch.
High load capacity: Common ratings are 5A–10A per channel, 500W–1000W+ per channel at 230V, and 3kW–4kW per channel for rack-type stage dimmers.
Built-in programs / standalone mode: Auto run, chase, fade, strobe, sound-active, and manual mode for testing or architectural scenes without a DMX console.
Flexible interfaces: XLR 3-pin / 5-pin, RJ45, or terminal-block DMX IN/OUT; mains input/output via screw terminals, Edison, Schuko, or IEC sockets depending on market.
Soft-start / inrush control: Reduces lamp strike current and extends lamp/LED-driver life; configurable minimum level (e.g., 1%–40%) prevents LED dropout at low values.
Signal-loss behavior configurable: Hold last level, fade to 0%, snap to full, or switch to standalone program on DMX loss.
Protection functions: Per-channel fuse/breaker, over-current, over-temperature with auto-recovery, short-circuit, surge protection, and galvanic isolation between DMX side and mains side.
Installation formats:
Dimmer pack — portable stage/DJ unit
Dimmer rack / rack-mounted dimmer — theatre and broadcast
DIN-rail dimmer — smart building / architectural lighting
Wall-mount / panel dimmer — hotel, KTV, bar, residence
Analog interface options: Many high-voltage DMX dimmers also offer 0–10V / 1–10V output, acting as DMX-to-analog converter for DALI/0-10V drivers.
Standards & safety: CE / RoHS / FCC / EN 61347/ EN 55015/ EN 61547/ UL options; flame-retardant enclosure, isolated terminals, IP20 indoor or higher IP rated outdoor versions.
A DMX512 high voltage dimmer lets a lighting console smoothly dim mains-powered loads (incandescent, halogen, dimmable LED, fluorescent) by converting DMX512 data into phase-cut or 0–10V control — replacing traditional rotary dimmers in stage, architectural, and commercial lighting systems.
