Product Value Features
• Stylish and sophisticated appearance. Looks like a tablet, and the rectangular appearance makes it easy to change
dimensions.
• Light and thin product. Cabinet dimension 1152x288mm, weighs only 8.8kg/cabinet(N4W 9.2kg), with only 54mm
thickness, with more than 25% reduction in weight and over 35% reduction in thickness compared to similar products in
the market.
• Brand new smart monitoring. Monitoring card not required to monitor signal receiving cards, modules, cables, tempera-
ture, LED, etc. Abreakthrough from traditional architecture, reducing wiring and failure points.
• Supports PCs, tablets, mobile phones and other smart terminals to connect to the display for monitoring screen
operation.
• Smart Modules: Module can store ID number, production date, order information, usage duration, color coordinates,
current and other information. More convenient and practical.
• Complete front or rear maintenance. Perfect for environments where only rear maintenance is available like window
display, but also perfect for environments where only front maintenance is allowed, such as wall mounted installation at
malls.
• Complete front installation and maintenance can be adopted for wall-mounted installation, with magnetic modules,
power supply, signal receiving card, HUB, cable wirings, etc., accessible from the front, ensuring easy and fast
servicing, and zero maintenance channel requirement.
• Magnetic modules enable fast and convenient module installation and disassembly without screws.
• Cabinets can be installed both horizontally and vertically. The module can be rotated along with cabinets by 90 degrees
for assembly (rotating the module and cabinet together does not affect the viewing angle), ensuring the screen can be
installed vertically, to meet customers’ different installation requirements.
• Sub-frame enables faster installation.
• Fan-less design for cabinets and power supply, eliminating noise and reducing power consumption. More energy
savings.
• Uses crystal head sockets and reliable power plug sockets for signal and power cable connections between cabinets
and signal source, and power plug and socket, for faster and safer connections.
• Easy cabinet testing and operating status monitoring with external test button and indicators.
• High definition ensures excellent and super clear display effect. No ghost shadows or caterpillar problems, with high
grayscale, high refresh rate, and high grayscale at low brightness, highlighting exceptional display affect.
• Super large viewing angle, high contrast ratio: 160/140 no dark spots phenomenon. Uses TOP type SMD LED,
combined with light trap mask design, ensuring excellent optical effects.
• Supports Absen’s 3rd Generation Pixel-by-Pixel Correction (A3C) technology, ensuring even images. Different batches
produced within one year can be mixed and used together. Module is designed with built-in data correction memory, so
that users can directly replace modules without cumbersome setup, and can easily import and calibrate data.

Sub-frame
A floor support stand is required for floor installation, so that cabinets can be mounted onto the support
stand.
When installing, first fix 4 (2 to 4) cabinets onto the sub-frame, and then mount the sub-frame onto the steel
structure or wall, to achieve fast installation.
Note: Front or rear installation can also be used for sub-frame installation.

• Preparation before wiring
Before connecting to power supply and switching on control signal to the entire screen, please carefully
check the power supply and signal cable connections. Please carefully check the "L" line, "N" line and "PE" of
each cabinet’s AC inlet, and ensure there is no short circuit between the three lines (Use multimeter to
measure).
• Power Supply Cabling Instructions
Please calculate and select the power distribution box or socket type based on 450 w/m2 (N4W 540w/m2)
maximum power consumption. Please consult your power distribution box manufacturer to specifically match.
Cabinet’s input voltage is 100-240V/AC, and 3X1.5mm2power cable is used to connect from distribution box
to cabinet. When input voltage is 220V, each power supply can be used to supply power for maximum 16
cabinets. When the input voltage is 110V, each power supply can be used to supply power for maximum 8
cabinets.

After completing the cabinet wiring, please use a multimeter to check if there is any short circuit at the AC
input power supply (L / N / PE) and DC output terminal (VCC / GND). If there is a short circuit, please
carefully investigate the wirings. Make sure all wirings are normal, and only then connect power to operate
the unit.
