DALI IP66 Außentreiber: Tridonic, Helvar und Osram Auswahl für wetterfeste Leuchtensteuerung

Tridonic basicDIM IP66 Treiber – Hauptspezifikationen

Tridonic LCI 25W 150–700mA one4all sc IP66:
  Output power:     25W

  IP rating:        IP66
  IK rating:        IK08
  Operating temp:   -40°C to +50°C (cold start: -40°C)
  Dimensions:       165 × 43 × 30mm
  Mounting:         Internal to luminaire or weatherproof enclosure

Tridonic LCI 75W 150–1400mA one4all sc IP66:
  Output power:     75W
  Output current:   150–1400mA (constant current, adjustable)
  Dimming:          DALI-2
  IP rating:        IP66
  IK rating:        IK08
  Operating temp:   -40°C to +50°C
  Dimensions:       230 × 50 × 37mm

DALI-2 device type:  Type 8 (colour control, Tw + xy)
                     Type 6 (standard dimming only)
Both types support DALI-2 bus power (no external supply needed
  for the DALI interface — bus powered from gateway)

Spezifikation der DALI-Busverkabelung im Außenbereich

Cable: NYM-J 3×1.5mm² or NYFAZ 3×1.5mm² (230V + DALI in same cable)
  — unshielded, standard installation cable
  — DALI bus is 2 of the 3 cores (polarity-free)
  — 3rd core: protective earth for luminaire body bonding

Max bus length:     300m (IEC 62386 specification)
Max devices:        64 DALI devices per segment (not 64 per gateway)
Topology:           Daisy-chain or star — both permitted
                    T-junctions permitted (unlike KNX TP)

Outdoor routing options:
  Option A: In rigid PVC conduit (EN50086-2-2) above ground
    — UV-resistant grey conduit, IP67 junction boxes
    — Suitable for wall-mounted luminaires, pole conduit runs

  Option B: In buried ducting (HDPE corrugated duct)
    — Min 500mm depth for footpaths, 700mm under driveways
    — Draw-wire installed for future cable replacement
    — Separate ducts for mains and DALI (or use SWA)

  Option C: Steel wire armoured (SWA) cable, direct buried
    — NYBY 3×1.5mm² or 5×1.5mm² (230V + DALI + earth)
    — No conduit required, buried at 600mm depth
    — Armour bonded to earth at distribution board end only

Überspannungsschutz für Außen-DALI

At distribution board (gateway end):
  Mains supply:    Type 2 SPD on 230V feed to DALI gateway
                   (e.g. Phoenix Contact VARISTOR 1+0 type 2)
  DALI bus:        TVS diode pair across DALI+ and DALI−
                   Clamping voltage: 18V (DALI bus = 16V nominal)
                   (e.g. Littelfuse SMBJ15A bidirectional TVS)
  Earth bonding:   DALI bus 0V (DALI−) bonded to PE at one point
                   (gateway end only — avoid earth loops in long runs)

At each outdoor junction box (intermediate points):
  Weatherproof box: IP67 minimum (Hensel Mi series or equivalent)
  DALI bus joints:  Wago 221 push-in connectors (rated to IP20 in box)
  Earth continuity: Luminaire body → green/yellow to PE bar in box

At luminaire:
  Luminaire body:  Bonded to protective earth (third core of cable)
  Driver earth:    Driver PE terminal connected to luminaire body
  DALI bus:        Direct to driver DALI terminals — no further protection
                   (driver internal TVS provides local protection)
