Depending on the number of fixtures the LED modules will function at half (2 LED's), one third (3
LED's) the luminous intensity. Moreover, due to different forward voltages the current will not split
in equal part.
Risk for an output voltage that exceeds the max for the LED.
A power supply that is switched on has max output on the secundary side
(eg. 49V). The LED in eg. a Reo 3030 is 7W works at 350mA and 20,1V.
49V is far too high for the Reo 3030 >>
LED will be damaged.
Question:
How many Reo (7W) luminaires can be connected
to power supply 300 90 914?
7W x 4 = 28W >>> max power of 300 90 914 = 35W >>> OK
4 x 20,1V = 80,4V >>> max voltage of 300 90 914 = 72V >>> NOT OK
Answer:
3 x Reo (7W) luminaires can be connected to power supply 300 90 914
Therefore: always consult the matrix on FOLD-OUT!
CONNECTION
Electrical devices are sensitive for excessive voltage peaks.
Especially outdoor power lines are subject to direct and indirect lightning discharges. Also in industrial or semi-industrial area’s the
powerlines can be subject to high switching spikes. Therefore Deltalight strongly advices to use proper power line surge protection.
Our AC surge protectors are to be installed on the primary side of led power supplies and the DC types on the secondary side.
Both as close as possible to the device they have to protect.
