TCI DC JOLLY US 32 |1-10 V & PUSH | 126421 | 151421

Product information "TCI DC JOLLY US 32 |1-10 V & PUSH | 126421 | 151421"

LED driver DC Jolly up to 32W dimmable via push button or 1-10V

Suitable for 68mm ceiling holes for e.g. ceiling installation of LED spots.

  • TCI DC Jolly: Universally dimmable over 1-10V
  • Touch dimmer input of the DC Jolly
    On/Off by briefly pressing the button, changing the brightness with the button held down.
  • Easily adjustable constant current or voltage via dip-switches.
    Thus a universally applicable multi-current or multi-voltage converter. 
  • Flicker (output ripple) <= 3%
  • available in different versions (PWM, Hybrid, AM)

The Jolly US 32 can be used for to 32 watts power. Current versions offer PWM, Hybrid (AM+PWM) and AM-only regulation/dimming.

TCI 126421 (up to 32W) is the technologically improved successor of #125421. (Previous models in short description see below). Its innovation is the combination of PWM and AM control. This so-called hybrid control ensures absolutely flicker-free light in the range of 100% - 25% by linear control. Only in the range below 25% to 1% is there a switchover to the familiar PWM control. Thus the advantages of both methods are used.

By removing a jumper (JP3) it is possible to switch back to "PWM-only" (incl. activation of constant voltage operation). (see 125421).
In addition, further setting options for the currents have been added.

TCI 151421 (up to 32W) is a pure linear controller. The LED current can be dimmed linearly (AM) from 100% to 1%. Perfectly suitable for Dim2Warm.

Attention: No constant voltage operation adjustable as well as no operation with synchronization lines (Master-Slave) possible.

Please also read this technical article about PWM/AM/Hybrid dimming modes.

As a proven multi-current converter - universally applicable. Also available as Built-In version (TCI 126450, TCI 151450)

History ( predecessor ) of the approved LED driver DC Jolly 1-10V & PUSH 

TCI 122420 with up to 25 Watt. constant current, or -voltage. Everything adjustable via dip switches. The LED current is regulated without exception via pulse width modulation (PWM) ( discontinued - successor 126421) 

TCI 122421/123421 with up to 32 Watt. Almost identical to the 122420 with slightly higher power and wider setting ranges for the constant currents and constant voltage outputs ( discontinued - successor 126421) 

TCI 125421 with up to 32 Watt. Almost identical to the 123421 but with considerably more setting ranges for the constant currents ( discontinued - successor 126421)
