TCI Professionale DALI 38

Product information "TCI Professionale DALI 38"

Direct current dimmable electronic drivers with DIP-SWITCH #127490, #127492

Features of Professionale DALI 38

  • Multipower driver supplied with dip-switch for the selection of the output current.
  • IP20 independent driver, for indoor use (PROFESSIONALE DALI).
  • Class II protection against electric shock for direct or indirect contact (PROFESSIONALE DALI).
  • Driver for built-in use (PROFESSIONALE DALI BI).
  • It can be used for lighting equipment in protection class I and II (PROFESSIONALE DALI BI).
  • Active Power Factor Corrector.
  • Current regulation ±5 % including temperature variations.
  • Input and output terminal blocks on opposite sides (wire cross-section up to 1,5 mm2 / AWG15).
  • Clamping screws on primary and secondary circuits for cables with diameter: min. 2 mm - max. 9 mm
  • Driver can be secured with slot for screws.
  • Protections:
    • against overheating and short circuits;
    • against mains voltage spikes;
    • against overloads.
  • Thermal protection = C.5.a.

Operation Mode

  • Features DALI dimming (0/1 - 100 %):
    • memory function for sets or light groups;
    • recall of stored functions;
    • compatible with standard DALI interfaces.
  • DALI dimming is the default setting ((3) DALI 2.0 ready)
  • Light regulation 0/1 - 100 % by means of PUSH SWITCH function (mains voltage):
    • a short push to turn on and off;
    • a longer push to increase or decrease light intensity;
    • regulation automatically stops at minimum and maximum values;
    • for another on, regulation or off command, release the push button and give the desired command again;
    • dimming level memory at mains restore;
    • keep enabled the SWITCH for at least 10 seconds to reset the dimming level to 30%;
    • keep enabled the SWITCH for at least 60 seconds to enable
Amplitude dimming - linear dimming - flicker freeCharacteristics of this constant current driver:

 Beside of a DALI-Interface, which also can be used for Push dimming (see following picture), this EVG is designed for amplitude dimming. It creates totally flickerfree light (none PWM). The dimming sector is between 1% -100%.


BILEVEL N function:

  • keep pressed for 100% level;
  • FADE OFF time is 30 seconds, light level 10%;
  • PROLONG time is 30 minutes, then OFF.
