New Low-Drop Version!

The linear PowerLine constant current power supplies are charachterized by higher operating ranges and actually PWM capability (Pulse-Width Modulation). We were often asked why we a 1400mA version instead of a 1500mA version. Modern power supplies are running very stable of course but there can still be little fluctuation and if you run a 1500mA version that jitters upwards it could cause damadge to the LEDs.

If you do not know exactly what the sence of those power supllies is pleas eread the following lines:

Even high power LED application can only guaranty 100% of the LEDs lifetime if the illuminants get a constant curent supply. You have the possibility to use a constant current power supply with a step-down converter (product example) that come sin a very small housing but is not able to be used in a RGB application.

The other possibility is to use a linear constant current power supply. It is a little bigger than a step-down converter because of its necessary cooling element but it is not too big as the beside mentioned gallery foto shows.

SLIM verions: The PowerLine constant current power supplies are available without cooling elements, too.

Converting and quality are on highest levels. Connecting is vey easy too because the clamps are clearly defined by inscriptions. Please read below the further features of this powerful little helper.

Techical data:

- Drop voltage: 1V
- Input: 30V DC (max.)
- Output: 1400mA constant

- Input short circuit protection
- Output short circuit protection
- Cooling element electrical isolated!
- Autom. current reduktion if too much heat!
- Operating Temp: ~50°C over ambient temp.
- Max. input voltage: 7V over LED voltage

- 2 mounting eyes
- Dimesnions (W/H/D): 33 x 21 x 63 mm

Example 1:
You are going to connect five white Luxeon K2 LEDs with 3,85 forward voltage each (mostly mentioned as Vf in common datasheets). The input voltage can change from 20,25V (3,85 + 3,85 + 3,85 + 3,85 + 3,85 + 1,0) till 27,25V (20,25 + 7). A 24V power supply would be the best in that case. A 12V power supply would be too small.

Example 2:
You are goint to connect two blue Luxeon K2 LED (3,85V). The input voltage can change from 8,7V (3,85 + 3,85 + 1,0) till 15,7V (8,7 + 7). In that case a 12V power supply would be better perfect. A 24V version would be too big.
