New Low-Drop Version!

The linear PowerLine constant current power supplies are charachterized by higher operating ranges and actually PWM capability (Pulse-Width Modulation). 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: 700mA 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: 13V over LED voltage

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

Example 1:
You are going to connect three white Luxeon LEDs with 3,7 forward voltage each (mostly mentioned as Vf in common datasheets). The input voltage can change from 12,1V (3,7 + 3,7 + 3,7 + 1,0) till 25,1V (12,1 + 13,0). A 24V power supply would be the best in that case.

Example 2:
You are goint to connect two red Luxeon LEDs (2,95V). The input voltage can change from 6,80V (2,95 + 2,95 + 1,0) till 19,80V (6,80 + 13,0). In that case a 12V power supply would be the best.

If you have any questions please send us an email.
