Features of 4-LED Single Color 3-LED High Voltage LED Module
1. Direct AC110V or AC220V Operation
The YS-MP3336/YS-MP3337 3-LED High Voltage LED Module is available in versions for AC110V and AC220V input. The direct mains design removes the need for a conventional low-voltage transformer for the module itself, which can simplify the power architecture of larger signage systems. Direct AC operation is a common advantage highlighted for high-voltage signage modules.
2. Constant-Currrent High-Voltage Design
The built-in electrical design uses constant-current control to help regulate the LED operating current under the rated input conditions. This supports more stable operation across connected modules and is particularly useful for long signage installations.
3. Single-Module Cutting
The supplied specification identifies the module as single-module cuttable, providing flexibility when adapting the lighting arrangement to different sign dimensions and graphic shapes.
4. Designed for Even Sign Illumination
The wide optical distribution allows the three LED light sources to cover a larger area inside the sign cavity. With the correct module spacing, the lighting layout can provide a more balanced appearance across translucent acrylic or other sign-face materials.

Single Color 3-LED High Voltage LED Module Wiring Diagram & Installation Guide

Installation Precautions
1. This module directly uses the mains (AC 220V), no need to buy a power supply, and the installation is convenient and simple
2. After installation, when the voltage is turned on, it is forbidden to touch the module with metal or hands
3. It is best to use terminal wiring when connecting to electricity, and double-ended power supply is prohibited for wiring.
4. Waterproof treatment and anti-leakage treatment should be done at the outlets at both ends of the module
5. Leakage switch or controller switch must be used (with short circuit protection, overload protection)
6. The installation surface should be flat, clean and dry
7. When wiring and installing, live operation is prohibited
8. During transportation, avoid rain and mechanical vibration

Recommended Applications for Single Color 3-LED High Voltage LED Module
1. Single-Sided Advertising Light Box
The YS-MP3336/YS-MP3337 High Voltage LED Module is designed for rear-mounted illumination of single-sided advertising light boxes. The 160° optical distribution allows the light to spread broadly across the face of the cabinet.
2. Airport and Metro Advertising Displays
The product can be incorporated into suitably constructed advertising light boxes used in airports, metro stations and other transportation facilities, where signs may remain illuminated for extended periods.
3. Outdoor Advertising Boxes
With IP65 protection, the module can be incorporated into appropriately sealed outdoor light boxes and advertising signs. The overall cabinet and electrical connections should also be designed for the local outdoor conditions.
4. Retail Store Advertising Signs
