The **WLS28-2X850S** is a high-quality industrial LED strip light manufactured by **Banner Engineering**. It is designed for harsh industrial environments, providing bright, even illumination with low power consumption. ### Technical Specifications Overview | Feature | Specification | | :--- | :--- | | **Operating Voltage** | 12 V DC to 30 V DC | | **Luminous Length** | 850 mm | | **Current Draw** | Max 1.38 A at 12V DC / 0.55 A at 30V DC | | **Light Color** | Cool White (standard) | | **Housing Material** | Anodized Aluminum | | **IP Rating** | IP50 (Standard) | | **Connection** | 4-pin M12 Quick Disconnect or Integral Cable | --- ### Key Electronic Components and Features #### 1. Internal Constant Current Driver The WLS28-2 series features built-in control circuitry. Unlike simple LED strips that require external resistors or drivers, this unit has an **integrated constant current driver**. * **Benefit:** Ensures consistent brightness regardless of fluctuations in the input voltage (within the 12-30V range). * **Protection:** Protects the LEDs from overcurrent and thermal damage. #### 2. LED Array Configuration * **High-Intensity LEDs:** Uses Surface Mount Device (SMD) LEDs optimized for high lumen output and thermal management. * **Diffusion:** The electronic assembly is housed behind a clear or diffuse polycarbonate window to eliminate hot spots and provide uniform light distribution. #### 3. Dimming and Control The device supports **Pulse Width Modulation (PWM)** for dimming. * By applying a PWM signal to the control line, the intensity of the light can be adjusted from 0% to 100%. * This is typically handled by an external PLC (Programmable Logic Controller) or a manual dimmer switch. #### 4. Wiring and Pinout (M12 Connector) If using the standard 4-pin M12/Euro-style connector, the electronic interface is as follows: | Pin | Wire Color | Function | | :--- | :--- | :--- | | 1 | Brown | +12 to 30V DC | | 2 | White | Not Used / Optional Dimming | | 3 | Blue | DC Common (Ground) | | 4 | Black | Not Used | --- ### Protection Circuitry The internal electronics include several safety layers: * **Reverse Polarity Protection:** Prevents damage if the positive and negative wires are swapped. * **Transient Voltage Suppression:** Protects the LEDs from voltage spikes common in industrial power grids. * **Thermal Management:** The aluminum housing acts as a heat sink, drawing heat away from the PCB to extend the lifespan of the LEDs (rated for 50,000+ hours).
