TD - Power Supply LP DALI & Switch Dim PRE (CC) - IP20
User Manual - 75W / 900 -1.800mA
1. Product Description
The TD-Power Supply LP DALI & Switch Dim PRE is a dimmable constant current LED driver for
ceiling installation. Power supply and dimmer are in one housing. It can be controlled by means
of a DALI signal as well as with commerciallly available push-buttons (push, touch or switch dim
function). The output current is adjustable from 900 - 1.800mA.
Suitable for emergency escape lighting systems acc. to EN50172

Page 2: Installation And Wiring
4. Dimensions Dimensions 6. Installation and wiring Wiring type and cross section Solid wire with a cross section of 0.5 – 1.5 mm². Strip 8 – 9 mm of insulation from the cables to ensure perfect operation of terminals. LED module/LED-driver/supply Loose wiring Loosen wire through twisting and pulling or using a 1 mm diameter release tool... - Page 3 Wiring guidlines - 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.

Page 7: Interface / Communications
8. Interface / communications 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. - Page 8 9. Functiones 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.
- Page 9 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).
- Page 10 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.
- Page 11 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: < 32.7 mA DC: < 2.8 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-875-901 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.
