Power Wiring
- Please follow the PSU selection guidelines below in order to
select the correct Power Supply.
- Use at least 18 AWG (0.75mm2) for DC Power In connection.
- It is highly recommended to connect all 4 terminals of the
Power In screw terminal block.
Important
Maintain correct polarity when connecting the Power Supply.
Failure to do so may cause damage to the Unit.
PSU selection guidelines
The PSU must be selected while considering the maximal num-
ber of serried LEDs per channel in the application, output cable
type/length and the power rating needed to drive the LEDs at
the desired current.
Below is a table that illustrates the relationship between the
variables
PSU selection table for High-Power LED xtures
The calculations were made assuming the following conditions:
- All 4 channels are equally loaded.
- 15% power was added to the nominal ratings as a minimal com-
pensation reserve for system eciency and drop voltage on the
output line.
The values presented in the tables of this section are general
guidelines only, and as such should be used with caution. Always
check the specications of the LED xtures used as a load and
conrm whether the conditions stated above satisfy the needed
requirements.
PSU selection table for COB LED xtures
The calculations were made assuming the following conditions:
- All 4 channels are equally loaded.
- 15% power was added to the nominal ratings as a minimal com-
pensation reserve for system eciency and drop voltage on the
output line.
- Red color means that the specied COB chain cannot be used
(due to high Vf).

guidelines only, and as such should be used with caution. Always
check the specications of the LED xtures used as a load and
conrm whether the conditions stated above satisfy the needed
requirements.
