Assembly Holes Dimensions
Above is the top view of the bottom shell. The specifications of the screws fixed in the customer system are M3, totaling 4. The length of the fixed screws entering the power supply body should not exceed 3.5mm.
Attention For Application
Power supply to be safe insulation, any side of the metal shell with the outside should be more than 8mm safe distance. If less than 8mm need to pad 1mm thickness above PVC sheet to strengthen the insulation.
Safe use, to avoid contact with the heat sink, resulting in electric shock.
PCB board mounting hole stud diameter not exceeding 8mm.
Need a L355mm*W240mm*H3mm aluminum plate as auxiliary heat sink.
How to make LED display brightness change automatically in different time ?
A: It is required with light sensor. Some devices can connect with sensor directly. Some devices need to add multi-functional card then can install light sensor.
How to customize video splicer, like Novastar H2?
A: At first decide how many LAN ports the screen need, then choose 16 ports or 20 ports sender card and quantity, then choose input signal that you want to use. H2 can install maximum 4 input board and 2 sending card board. If H2 device is not enough, can use H5, H9 or H15 to install more input or output boards.
How do I recognize which pitch LED display I should buy ?
A: Normally based on viewing distance. If viewing distance is 2.5 meter in meeting room, then P2.5 is best. If viewing distance is 10 meter outdoor, then P10 is the best.
What is the best aspect ratio for LED screen ?
A: The best view ratio is 16:9 or 4:3
