TD - Power Supply SC DALI & Switch Dim PRE (CC) - IP20 User Manual - 25W / 350-1050mA Item no.: NT-825-351 1. Product Description The TD-Power Supply SC DALI & Switch Dim PRE is a dimmable constant current LED driver for ceiling and furniture installation.
4. Dimensions Dimensions without strain-relief 6. Installation and wiring Wiring type and cross section The wiring can be in stranded wires with ferrules or solid with a cross section of 0.2–1.5 mm². Strip 8.5–9.5 mm of insulation from the cables to ensure perfect operation of the push-wire terminals.

Wiring guidellines - The cables should be run separately from the mains connections and mains cables to ensure good EMC conditions. - The LED wiring should be kept as short as possible to ensure good EMC. The max. secondary cable length is 2 m (4 m circuit), this applies for LED output as well as for I-select 2.
7. Electrical values Operating window Make sure that the LED Driver is operated within the given window under all operating conditions. Special attention needs to be paid at dimming and DC emergency operation as the forward voltage of the connected LED modules varies with the dimming level, due to the implemented amplitude dimming technology.

1) Valid at 100 % dimming level. 2) Depending on the selected output current. 3) Depending on the DALI traffic at the interface. 4) The table only lists a number of possible operating points but does not cover each single point. The output current can be set within the total value range in 1-mA-steps. 5) Not compatible with I-select (generation 1).
Dimming characteristic 8. Interface / Communication Control Input (DA/N, DA/L) Digital DALI signal or switchDIM can be wired on the same terminals (DA/N and DA/L). The control input is non-polar for digital control signals (DALI, DSI). The control signal is not SELV. Control cable has to be installed in accordance to the requirements of low voltage installations.

9. Functions Adjustable current The output current of the LED Driver can be adjusted in a certain range. For adjustment there are three options available. Option 1: DALI Adjustment is done by masterCONFIGURATOR (see masterCONFIGURATOR documentation). Option 2: I-select 2 By inserting a suitable resistor into the I-select 2 interface, the current value can be adjusted.

Short-circuit behaviour In case of a short-circuit at the LED output the LED output is switched off. After restart of the LED Driver the output will be activated again. The restart can either be done via mains reset or via interface (DALI, DSI, switchDIM, ready2mains).

switchDIM and corridorFUNCTION are very simple tools for controlling gears with conventional pushbuttons or motion sensors. To ensure correct operation a sinusoidal mains voltage with a frequency of 50 Hz or 60 Hz is required at the control input. Special attention must be paid to achieving clear zero crossings. Serious mains faults may impair the operation of switchDIM and corridorFUNCTION.

The voltage-dependent input current of Driver incl. LED module is depending on the used load. The voltage-dependent no-load current of Driver (without or defect LED module) is for: AC: < 17.2 mA DC: < 1.9 mA Software / programming With appropriate software and an interface different functions can be activated and various parameters can be configured in the LED Driver.
SIGNAL DA | L NT-825-351 | NT-845-514 Der Ausgangsstrom kann mittels Einsteckwiderständen, Programmiergerät oder DALI eingestellt werden. Wird kein Widerstand oder Drahtbrücke zwischen den I-SELECT Anschlüssen gesetzt, so gilt der am Gerät niedrigste Ausgangsstrom. Wird eine Drahtbrücke am I-SELECT Anschluss gesetzt, so gilt der am Gerät höchste Ausgangsstrom. Für Einstellwerte dazwischen werden Einsteckwiderstände benötigt.
