The LZ-4/FL is a passive device and allows to distribute the power supply. Additionally is equipped with filter, which eliminates interferences from switching adaptors and overvoltage limiter.
The housing of the LZ-4/FL has been prepared for mounting with screws to a wall or with a tie to a mast (tie, screws - not included).
For more devices than 4, the devices can be connected in parallel on the same terminal. Due to built-in filter, the maximal current using to power the devices must be below 6A.
